This is the real thing. The WX-202 is the genuine 20 gallon Pro series tank manufactured by Amtrol Inc. in West Warwick, Rhode Island. We source every unit through an Amtrol authorized wholesale distributor channel that serves the East Coast. Same factory, same SKU, same serial number range as what your local pump installer would put in. The tank ships with the official Amtrol silkscreened branding and 7-year warranty paperwork.

Amtrol's official Internet Sales Policy actually excludes online purchases from manufacturer support. That sounds bad - and it is for most online sellers - but it is not an issue when you buy from us. We back every sale through our authorized distributor channel. You call Mid Atlantic Water (not Amtrol), we help you get a replacement with our authorized distributor channel, our authorized distributor channel processes it through Amtrol on their dealer terms, and you get a replacement tank shipped on freight. You never deal with Amtrol directly. Most replacements ship in 5 to 10 business days.

Pick the WX-202 (32 in. tall, 20 gallon) over the WX-203 (47 in. tall, 32 gallon) when (a) you cannot fit a 47 in. tall tank in your basement, crawlspace, or pump house, (b) you have a smaller home with a 1-2 bath setup and a low-flow pump (5-8 GPM), or (c) you are replacing an existing 20 gallon tank and want a like-for-like swap. For most other residential setups the bigger WX-203 is the better long-term value because more drawdown means fewer pump cycles. Use the size pills above the cart to switch over and compare prices instantly.

About 8 gallons at 30/50 PSI service (the most common residential setting). That is enough for one shower, one washing machine fill, or one dishwasher cycle without the pump kicking on. If two fixtures run at once on a low-flow pump you will hear the pump cycle - that is normal for this size tank. If your household runs multiple fixtures simultaneously on a regular basis, step up to a WX-203 (about 11 gal drawdown) or a WX-250 (about 17 gal drawdown).

Amazon sellers ship the bare tank only - no tee package, no pressure switch, no gauge, no relief valve. By the time you buy those parts at the hardware store you are at $600-$700 for the tank alone. On top of that, you have no manufacturer warranty support (per Amtrol's own policy), the tank ships UPS/FedEx parcel where bladder damage is common, and the seller is non-returnable. Our $1,095 includes everything to plumb in, palletized freight, full warranty service, and 30 day returns - we handle the freight on a return.

Pre-charge equals your pump cut-in pressure minus 2 PSI - measured with NO water in the tank. Factory ships at 38 PSI which is correct for a 40/60 cut-in/cut-out switch. For 30/50 service (most common residential), drop it to 28 PSI. For 50/70 service, raise it to 48 PSI. Use a tire gauge on the air valve under the blue cap on top. Wrong pre-charge is the #1 cause of premature bladder failure - more than any manufacturing defect. Smaller tanks like the WX-202 are even more sensitive to wrong pre-charge because the drawdown margin is smaller.

A correctly sized and properly pre-charged Well-X-Trol Pro typically runs 10-15+ years. The 7-year warranty covers manufacturing defects, but realistic lifespan with annual pre-charge checks is much longer. The most common failure is the diaphragm, usually caused by repeated waterlogging from a wrong pre-charge. The pressure switch (a separate part) typically needs replacement every 5-8 years - that's normal for any switch.

Yes, as long as it doesn't freeze. The Tuf-Kote HG Blue finish is rated for indoor or outdoor use. The risk for outdoor installs is freezing - the tank will rupture if it freezes solid. Insulate the tank and tee, use heat tape, or install in a pump house. Anywhere that drops below 32 F is a no-go without freeze protection.

Yes, the tank ships factory pre-charged to 38 PSI. You should still verify with a tire gauge before plumbing it in (these tanks sit in warehouses for months and the charge can drift). If you need to adjust, a basic bicycle pump or 12V tire compressor works fine - you are only adjusting by 5-15 PSI. No shop compressor required.

Yes. The WX-202 has a standard 1 in. NPTF system connection that works with any submersible or jet pump on the market. The included pressure switch is a Square D / Pumptrol style 30/50 PSI factory set, field-adjustable to 20/40, 40/60, or 50/70. If you have an existing pressure switch you want to keep, just swap it onto the new tee. Wiring is the same.
