8 l Lead-Free Potable Water Thermal Expansion Tank

Product Overview

The 2.1 gallon XT-8 Thermal Expansion Tank is utilized on potable water lines between the backflow preventer or pressure reducing valve and the water heater for protection against water thermal expansion in residential applications. As the system pressure increases, water enters the polypropylene-lined water chamber of the tank, expanding a diaphragm into a pre-charged air chamber to keep the system pressure below the relief valve setting. Materials include a carbon steel shell with an epoxy finished coating, and corrosion-resistant stainless steel connection with a polypropylene liner and Butyl rubber diaphragm.
  • Pre-charge is field adjustable for convenient maintenance
  • Carbon steel shell with polypropylene liner ensures long-lasting construction
  • Diaphragm style tank is ideal for thermal expansion protection in residential applications
  • Stainless steel connection resists corrosion
  • Low-lead law compliant
  • IAPMO Listed
  • Water Quality Association - Certified to NSF/ANSI 61 & 372
  • Steel shell protected with polypropylene liner

Perfect fit/replacement for the previous zurn, no problems with the install. Came pre-charged at about 40psi, so i bumped it up to 54 psi to match my house pressure. Works fine.

In general, this expansion tank met my expectations. Instructions were sufficient, and I installed this myself, as local plumbers would not give a reasonable fixed price to do the work. This was a replacement install, in horizontal position over the top of the hot water heater tank. I used a shim to support the expansion tank, to avoid the weight of the full expansion tank from stressing the connection. I had some PTFE (Teflon) tape typically sold at big box stores, but it was not suitable for the deep threads, which kept cutting through the tape as I applied it. I had a small leak each of the first few times I installed, but eventually got the tape applied sufficiently so ended up leak free. It would have been a big help if the the product included a small amount of high quality tape (wider and thicker), so this issue could be avoided. If I have to do this again, I would buy some high quality tape first. The reason I rated this product 3 star instead of higher is because I was replacing the same tank make/model. When I took the ~12 year old tank off, the black bladder had failed, disintegrated, with pieces of black "rubber" coming out as I emptied the tank. I expect a product like this to be problem free for 20+ years, so I am concerned about the product life of the new tank.

Too soon to tell, really, it's only been in service a week. The packaging was fine. Charging the tank to match the pressure of my water system went easily with a bicycle pump. Installation was problem free. Not much to it.
