This Ames 4000ss repair went fairly smooth. The first time rebuild on the relief was humbling. I would recommend Watts Water Technologies make a 994 to 957 relief conversion adapter. It took 15 attempts to get the rubber part to fold just right. Thank you to Test Gauge & Backflow Supply for warning of what a pain it was going to be.

The 8" Ames 2000SE uses 6" check valves and are the same checks as the Watts Water Technologies model 774. This one required a #1 check replacement. Thanks to Test Gauge & Backflow Supply for insuring we were given the correct parts!
