      Exact replacement for ours. I pumped it up from the 40psi is comes precharged with to our line pressure of just over 70psi. This will help with it not being over stretched when first installed. It appears to help a bit with our washers hammer effect as well even tho we have hammer arrestors on the washer!

      Good value and exact match to our 11 year old one that came with the house.

      Ours needed to be replaced. Plumber wanted $500 to do the job. Took me about 10 minutes with basic tools. All for under $60.

      This is the second one - (preventive maintenance) got 12 years out of the first one. No leaks but the inlet was 95% clogged-no issue works as advertised.
