(25)GP FILTRE À EAU TRANSPARENT 1" I/O 80 MAILLES SS

Crystal-Clear Protection for Your Pump in One Look

The GP clear bowl water filter is an inline filter with a transparent polycarbonate bowl that lets you see exactly what's in your water supply before it ever reaches your pressure washer pump. Sand, rust flakes, sediment, organic debris - this filter catches it all and puts it on full display so you know the moment your screen needs attention. No guesswork, no sudden pressure drops, no nasty surprises mid-job.

GP filters are designed for inline use in pressure washing and irrigation systems, and inline strainers are typically located at the water inlet, serving as the first line of defense in pressure washing systems. Inline strainers remove large debris before it reaches the pump - they prevent rocks, twigs, and leaves from damaging the pump. Whether you're running a residential pressure washer off a garden hose, operating a trailer-mounted commercial rig pulling from a tank, or managing a fixed wash bay fed by municipal water, this filter sits between your water source and your pump to keep contaminants out. Visual monitoring is simplified by the clear construction of the filter bowl - one glance tells you if it's time for cleaning or if you're good to go. It's the kind of cheap insurance that saves you from expensive pump rebuilds down the road.

Why You'll Love the GP Clear Bowl Water Filter

This isn't a spec dump - it's about what this water filter actually does for you on the job, day after day. Filters enhance pressure washer performance and lifespan, and here's exactly how this one delivers.

• Immediate visual feedback – The transparent bowl lets you instantly see sediment buildup, air bubbles, or discolored water before any of it causes problems. Rust-tinted water from old pipes? Silt from a well? You'll spot it in seconds. That's preemptive maintenance instead of reactive repair, and it's crucial for avoiding downtime.

• Extends pump and nozzle life – Water filters prevent damage from debris in pressure washers. Capturing grit and particles upstream protects ceramic plungers, seals, check valves, and spray tips from abrasive wear. Filters capture small particles not visible to the eye - the kind that silently grind down your pump internals and nozzle orifices until something fails. Replacing a screen is pennies compared to rebuilding a pump head.

• Keeps pressure consistent – A clean mesh screen means stable flow with no restriction. You avoid the pulsation, performance loss, and unloader cycling issues that come from a starved inlet. Your pressure stays where it should be from the first trigger pull to the last, and cleaning performance doesn't fade halfway through a long job.

• Fast, tool-free maintenance – The bowl is designed for easy removal - twist it off by hand, pull the screen, rinse it under clean water, and reassemble. The whole process takes under a minute. No wrenches, no specialty tools, no downtime worth worrying about.

• Built for tough environments – The durable materials used in construction include nylon and EPDM for weather resistance. Stainless steel mesh screens handle corrosion and pressure without deforming. The filters generally withstand pressures up to 150 PSI at standard temperatures, which covers the inlet side of the vast majority of pressure washer setups. It's compatible with typical pressure washer detergents and pre-treatment chemistries you'd commonly encounter on the job.

• Works across setups – Available in multiple connection sizes, this filter fits trailer-mounted rigs, shop wash bays, and portable cold-water pressure washers drawing from spigots, tanks, totes, or even a faucet. Whether you're pulling from a garden hose or a large bulk tank, there's a configuration that fits your line without restricting flow.

What Makes the GP Clear Bowl Water Filter Different

Most generic opaque strainers hide everything happening inside. Users forget about them, neglect cleaning, and don't realize there's a problem until their pump is cavitating, their spray pattern is weak, or their seals are already shot. The GP clear bowl water filter is built differently - and that visibility changes everything.

• Clear polycarbonate bowl for instant inspection – Being able to see contamination, trapped air, and water level in real time prevents surprise failures. If you notice air bubbles collecting in the bowl, that's an early warning of suction-side leaks or air ingress that could cause cavitation. If the bowl looks like a bucket of mud, you know to stop and clean before your pump pays the price. The transparent bowl allows for visual inspection of sediment accumulation without disassembly.

• Fine mesh element with high flow – These filters use stainless steel mesh screens commonly rated at 50 or 80 mesh. An 80 mesh stainless steel filter is commonly used for finer sediment capture, while a 50-mesh filter is generally recommended for broader sediment filtration. Both mesh sizes provide enough open area to support pumps in the typical 2–8 GPM range without starving the inlet. It's a smart balance between debris capture and flow capacity - tight enough to protect your components, open enough to keep water moving.

• Robust seals and body – The O-rings and housing are designed to handle standard pressure washer inlet pressures and temperature ranges without leaking or cracking. EPDM seals resist common detergents, and the nylon body stands up to daily use and environmental exposure without corroding like cheaper metal housings can over time.

• Service-friendly design – Maintenance is designed to be quick and efficient with easily removable screens. Replacement screens, bowls, and O-rings are widely available and inexpensive. You're not forced to replace the entire filter assembly when one element wears out - just swap what's needed and get back to work. In the field, screens and O-rings outsell full housings by a large margin because the design lets you service individual parts.

• Designed for pressure washer use – This isn't a generic plumbing part repurposed for high pressure work. The filter assembly connects via standard NPT threads of varying sizes - ½", ¾", 1", 1¼", and 1½" - specifically sized to match pump inlet plumbing on residential and commercial units. Some models also accommodate garden hose thread connections for home setups. It's oriented and sized to work in the exact spot it needs to: between your water source and your pump.

How It Works

Here's the basic filtration process from water source to pump - simple in concept, effective in execution.

1. Install on the inlet side: Mount the GP clear bowl water filter between your water source (spigot, tank, tote, or well feed) and your pressure washer pump inlet. Orient the filter upright with the bowl facing down so sediment settles naturally to the bottom. Connect using the appropriate NPT or garden hose thread fittings to match your plumbing. Pressure washer filters are placed after the pump on the outlet side for different purposes, but this inlet filter goes before the pump - that's the whole point.

2. Water passes through the mesh screen: Incoming water flows into the clear bowl, where the stainless steel screen captures grit, sand, rust flakes, organic debris, and other particles. Gravity helps - heavier sediment settles in the bottom of the bowl while the mesh catches everything else. You can watch it happen in real time through the transparent housing.

3. Clean water feeds your pump: Screened water exits through the outlet port and enters the pump inlet. With contaminants removed, you reduce the risk of cavitation, seal damage, clogged spray tips, and premature wear on check valves and plungers. Your pump gets the clean, steady flow it needs to operate at full performance.

4. Visual check and quick cleaning: Before each job, glance at the bowl. If you see debris covering the screen, discolored water, or trapped air, shut off the water supply, twist off the bowl, remove the screen, and rinse it under clean water - flushing from the bowl side outward works best to push embedded debris free. Inspect the screen for damage, reseat the O-ring, and reinstall. Full flow restored, ready to work.

Product Details

Here are the key specs for easy reference and compatibility checking.

• Materials: Clear polycarbonate bowl, reinforced nylon body, stainless steel mesh screen, and EPDM rubber O-ring seals. These filters are not suitable for purifying drinking water as their purpose is sediment filtration - they're engineered to protect equipment, not produce potable water.

• Mesh rating: Standard 50 mesh (approximately 297 microns) or optional 80 mesh (approximately 177 microns). The 50 mesh handles broader sediment filtration while the 80 mesh captures finer particles for applications where water quality is particularly poor or pump tolerances are tight. Different mesh sizes let you match the filter to your water conditions.

• Connections: NPT female ports available in ½", ¾", 1", 1¼", and 1½" sizes. Some models include garden hose thread (GHT) adapters for residential use. Standard 3/4 inch garden hose connections fit most home pressure washers directly.

• Flow and pressure: Supports flow rates up to approximately 8 GPM depending on body size and mesh configuration. Maximum working pressure is typically rated at 150 PSI at 70°F, dropping to approximately 125 PSI at elevated temperatures around 125°F. Sizing the filter body one size larger than your line can help reduce pressure drop on higher-flow rigs.

• Temperature and fluid limits: Designed for cold to warm water use, typically rated up to around 140°F (60°C). Not intended for steam, hot water pressure washers above the rated temperature, aggressive acids, or solvents. Common pressure washer detergents are generally compatible with the EPDM seals and polycarbonate bowl.

• What's included: Assembled filter body, clear polycarbonate bowl, internal stainless steel mesh screen (50 mesh standard), EPDM O-ring seal, and installation instructions. Replacement screens, bowls, and O-ring kits are available separately.

Who the GP Clear Bowl Water Filter Is For

This filter fits anyone who runs a pressure washer and wants to protect the equipment that makes them money - or saves them money at home.

• Professional pressure washing contractors – If you're doing driveways, commercial building exteriors, fleet washing, or large flatwork, your pump runs hard every day. Variable water quality from hydrants, customer spigots, or portable tanks means debris is always a risk. This filter keeps your pump and nozzle protected so you're not eating the cost of repairs between jobs.

• Facilities and fleet managers – Fixed wash bays in warehouses, trucking depots, municipal yards, and equipment shops need consistent uptime. Even municipal water can carry rust and scale from aging pipes. This filter ensures your high pressure equipment stays online without unexpected shutdowns from clogged valves or damaged seals.

• Agricultural and ranch operations – Farms and ranches commonly deal with well water, pond water, or tank water loaded with silt, rust, algae, and organic material. Whether you're cleaning machinery, barns, pens, or feed lots, this filter handles the worst your water source can throw at it and keeps your pump alive.

• Small industrial and manufacturing sites – Parts cleaning, plant sanitation, and process rinsing often rely on water from on-site sources with variable quality. Scale from old piping, particulate from storage tanks, and intermittent chemical use all make inlet filtration crucial for protecting your other components downstream.

• Homeowners with well or hard water – If you're running a mid-tier pressure washer at home and drawing from a well, cistern, or old plumbing, water that looks clean in a bucket can still carry fine particles that damage nozzle orifices and pump seals. This filter provides visible, proactive protection for your investment - easy to install, easy to maintain.

How to Choose and Set Up Your GP Clear Bowl Water Filter

Getting the right configuration and installing it properly is the difference between a filter that works silently in the background and one that creates problems of its own.

• Match the connection size to your pump: Check your pump inlet size - commonly ½", ¾", or 1" - and choose a filter body with matching NPT or garden hose thread ports. Avoid necking down the line with reducers if possible, as restricting the inlet diameter can starve your pump of water and cause cavitation.

• Size for your flow rate: Know your pressure washer's GPM rating. If your pump draws 4 GPM, for example, you want a filter body and screen with enough surface area to pass that flow without a significant pressure drop. For rigs running 5–8 GPM, step up to a larger body (1" or 1½" port). Industry guidance suggests sizing the filter body one pipe size larger when possible to increase screen area and extend the time between cleanings.

• Place it before the pump, after any bulk tanks: Install the filter so the supply line from your water source feeds the filter first, then immediately into the pump inlet. Mount it upright with the bowl facing down - this lets sediment settle into the bottom of the bowl where it's visible and out of the flow path.

• Use proper hoses and fittings: Use reinforced suction hose that maintains its internal diameter under vacuum - collapsed hose is a common cause of flow restriction. Seal threaded connections with non-hardening thread sealant compatible with plastic and polycarbonate components. Avoid over-tightening the bowl - hand-tight with a slight snug is sufficient. Wrenching down on it is a common cause of bowl cracking.

• Prime and leak-check: Before full operation, fill the supply line with water and let the bowl fill completely to push out trapped air. Check all joints for leaks. Start the pump with the wand cracked open to prevent pressure spikes, and watch the clear bowl for air bubbles that would indicate suction-side leaks or air ingress.

• Plan for service access: Mount the filter where you can easily reach the bowl without removing panels, hoses, or other plumbing. You need enough clearance below the bowl to unscrew it and pull the screen. On trailer or skid-mounted rigs, consider a dedicated mounting bracket that keeps the filter accessible and protected from shifting cargo.

Keeping Your GP Clear Bowl Water Filter Working for Years

Simple routine checks protect both the filter and your pump, extending the longevity of your entire system. A few minutes of attention prevents hours of downtime and hundreds in repair costs.

• Daily or pre-job inspections: Before starting each job, glance at the bowl. Visible sediment, discoloration (brown tint from rust, green from algae), or air pockets all tell you something. If the bowl looks dirty or the screen is visibly loaded, clean it before you start. Also monitor during long jobs - if cleaning performance fades or you notice pulsation, the screen may be clogging mid-use.

• Regular cleaning routine: Shut off intake, relieve pressure, unscrew the bowl, and remove the screen. Rinse under clean water, flushing from the bowl side outward to push embedded debris free. For fine silt, use a soft nylon brush. Inspect the O-ring for cracks or loss of elasticity, and lubricate it with a compatible lubricant if needed before reassembly. Make sure the O-ring seats properly - a misaligned seal means leaks.

• Monitor for pressure drop: If your spray pattern weakens, your wand output drops, or you notice the pump cycling the unloader more frequently, suspect a restriction at the filter. A clogged screen is the most common culprit. Catching it early prevents the low flow conditions that lead to cavitation and seal damage.

• Replace worn elements: Screens and O-rings are consumables - plan on replacing them periodically. If the mesh appears frayed, dented, torn, or permanently deformed, swap it out. A compromised screen can collapse under suction, dumping all its trapped debris directly into your pump in one shot. Replacement screens and seal kits are inexpensive and widely available.

• Cold-weather storage: After use in freezing climates, drain the bowl and supply line completely. Water left in a polycarbonate bowl will expand when it freezes, cracking the housing. Optionally remove the bowl and store it indoors during winter if your equipment lives outside.

• Protect from UV and impacts: Polycarbonate is tough but susceptible to UV damage over time - it'll yellow, haze, and become brittle with prolonged sun exposure, reducing the visibility that makes this filter valuable in the first place. If mounted in direct sunlight, consider shading it. Also protect the bowl from tool strikes, dropped equipment, and vibration on trailers - mount it securely and away from high-traffic areas on your rig.

Frequently Asked Questions

Here are the most common questions about sizing, use, and care of the GP clear bowl water filter.

Do I still need a filter if my water looks clean? Absolutely. Water that appears clear in a bucket can still carry fine particles, rust flakes, micro-sediment, and pipe scale that are invisible to the naked eye. These contaminants silently abrade pump seals, wear plunger sleeves, and clog nozzle orifices over time. A clear bowl filter is cheap insurance against repairs that cost many times more.

How often should I clean the clear bowl filter? For treated municipal water, check it weekly and clean when you see visible debris or discoloration. For dirty sources - wells, tanks, surface water, hydrants near construction - inspect and clean before each job. Anytime you notice a drop in pressure or flow at the wand, the screen is the first thing to check.

Will it restrict flow to my high-GPM pressure washer? When sized correctly and kept clean, the filter supports typical 2–8 GPM commercial units without starving the pump. The key is matching body size to your flow rate and not letting sediment load build up on the screen. Using too fine a mesh on a high-flow rig, or running an undersized body, will restrict flow - so size up when in doubt.

Can I use it with hot water? The standard GP clear bowl filter is designed for cold to warm water within its temperature rating - typically up to around 140°F (60°C). Hotter systems, steam pressure washers, or aggressive chemical applications may need specialized high-temperature filters with metal bodies and Viton seals. Always check the manufacturer's temperature rating before running hot water through a polycarbonate bowl.

What happens if I run it without cleaning? A clogged filter starves the pump of water, causing cavitation - that's when low inlet pressure causes water to vaporize inside the pump head. The result is noisy operation, overheated seals, accelerated plunger wear, clogged spray tips, inconsistent pressure, and eventually pump failure. The cost of a quick screen rinse is nothing compared to a pump rebuild. Don't skip it.
