Hey folks, question about water hammer arrester size. I have an outside faucet that is fed by a 3/4 in copper line directly off the main in the house. I set it up this way to bypass the softener and filter and have a high-flow outlet for filling our pool.
Well grass planting season is upon us and the timer I bought and put on this faucet is not soft close, it is a sudden slam, resulting in terrible water hammer. I happen to have on hand a 1/2" cash acme sweat-fit hammer arrester, and for some un-remembered reason I put a tee in the 3/4" line right before the pipe leaves the house. This tee has a 4" section of pipe then is capped and would be perfect for the hammer arrester, I even have a 3/4" to 1/2" adapter in my plumbing drawer.
I read something about "fixture units" and sizing these things but really just need to know if this will do the job and save myself a trip to the home despot. The model is CM500-SWA. House water presser regulator set to 65 psi (and tested). The run from the tee off the main to this faucet is about 20' with nothing else fed by it.
