Pure Water System Warranty

Effective October 20, 2026

We put together every pure water system we sell, and the same setup runs on our own truck every day. Here's how we stand behind yours, whether you bought the 3-stage RO/DI system on its own or as part of the Tri-Boss kit.

Your coverage at a glance

Lifetime: the cart frame and the stainless steel membrane housing, for as long as you own the system.
1 year: the clear and blue filter housings, gauge, built-in TDS meter, fittings, valves, tubing, wheels and our assembly work.
Lifetime help: call or text us with questions for as long as you own it.
Not covered: filters, the RO membrane, DI resin, O-rings, everyday wear and damage.

Lifetime coverage: frame and membrane housing

For as long as you, the original buyer, own the system, we cover these parts against defects in materials and workmanship:

The rolling cart frame and handle
The stainless steel RO membrane housing

If either of these parts cracks, splits or fails structurally during normal use because of a defect, we'll repair or replace it.

1-year coverage: components and assembly

For 1 year from your purchase date, we cover the other parts that came installed on your system against defects in materials and workmanship. That includes the clear pre-filter housing, the blue DI housing, the pressure gauge, built-in TDS meter, brass swivel inlet, fittings, valves, internal tubing and wheels.

It also covers our assembly work. If a connection we made fails because of how we put it together, we'll make it right.

About leaks: a leak is covered only when it comes from a defective part or our assembly. Leaks from a cross-threaded or over-tightened connection, a missing, pinched or worn O-ring, thread tape, or a hose or adapter you added aren't covered. Most leaks are fixed by reseating the O-ring and snugging the housing with the filter wrench, so give us a call before you take anything apart.

Lifetime help

Separate from the warranty, you can call or text us for as long as you own the system. Setup questions, troubleshooting, making sense of your TDS readings, finding the right replacement filter: we're happy to help. The help is free. Parts, shipping and repairs outside the warranty are not.

What's not covered

Filters and other consumables. The carbon pre-filter, RO membrane and DI resin are made to be used up and replaced, so they aren't covered. Our Setup & Care Guide explains when to change each one. O-rings and washers are wear parts, too. If a filter, membrane or resin cartridge seems faulty on your very first setup, contact us right away.

Everyday wear. Scratches, scuffs, cloudy or faded plastic, stains, surface rust on hardware and worn wheels come with daily use and aren't defects.

Damage. Problems caused by any of these aren't covered:

Freezing. Frozen water cracks housings and ruins membranes, so follow the winter storage steps in our Setup & Care Guide.
Drops, tip-overs, crushing, or the system sliding around loose in a truck or trailer
Pulling or dragging the system by its hoses or fittings
Pressure spikes, water hammer, or running the system on a booster pump without checking with us first
Cross-threaded, over-tightened or under-tightened housings and fittings
Chemicals, liquids other than water, or long-term sun exposure
Modifications, add-on parts that cause the problem, or repairs not done by us
Shipping damage not reported within 48 hours of delivery

Used systems. This warranty only covers systems bought new from The Window Cleaning Shop. It doesn't transfer to a second owner.

How to make a claim

Reach out. Call or text 832-755-2755 or email welcome@thewindowcleaningshop.com.
Show us the problem. Send your order number (or the name and phone number on your pickup order), clear photos, and a quick note on what's happening and when it started. If it's a water quality issue, include your tap water and pure water TDS readings.
Try the quick fixes. A lot of problems can be solved over the phone, so we'll walk you through a few checks first.
Send or bring the part if we ask. If we need to inspect something, we'll tell you how to ship it, or you can bring it by in Richmond, TX. Please don't ship anything back without talking to us first.

What we'll do

If we confirm a covered defect, we'll repair the part or replace it with a new or equivalent one. If a repair or part swap doesn't make sense, we may replace the system with an equivalent one instead. A replacement part may look a little different from the original, but it will do the same job.

Shipping: for approved claims in the first year after purchase, we ship replacement parts free by standard ground shipping within the continental U.S. After the first year, the part is still free, but shipping is on you. You can always pick up replacement parts free in Richmond, TX. Sending a part back to us for inspection, faster shipping, and shipping outside the continental U.S. are on you.

Labor: most parts swap out with basic tools, and we'll talk you through it. Labor, installation and on-site service aren't covered.

The fine print

This warranty is for the original buyer only, and we'll need proof of purchase.
A replacement part is covered for the rest of the original warranty on that part. It doesn't start a new one.
We decide whether a claim is covered based on the photos, information and any parts you send us.
Repairing or replacing the covered part, or the system, is the only remedy under this warranty. We aren't responsible for lost jobs, lost income, downtime, labor, travel or other indirect or incidental costs, and our total responsibility for any claim is limited to what you paid for the system. Some states don't allow limits on incidental or consequential damages, so this limit may not apply to you.
Any implied warranties, including merchantability and fitness for a particular purpose, last only as long as the written warranty on that part. Some states don't allow limits on how long an implied warranty lasts, so this limit may not apply to you.
This warranty gives you specific legal rights, and you may also have other rights that vary from state to state.
We may update this warranty. The version posted on the day you bought your system is the one that applies to it.

Poles and everything else

Our 30 ft water-fed pole has its own Limited Lifetime Pole Warranty. Hoses, brushes, TDS meters and fittings sold separately come with our 1-year limited warranty against manufacturer defects.
