Quick plumbing question


When running your pipes and making a mid-run 90 turn from vertical to horizontal, should you do this with a 90 or with a T and put an 8" capped piece sticking up, to dampen any possible water hammer? Or should you only do this at the fixtures?

Quick plumbing question


Water hammer arrestors or air chambers should be as close to the valve as possible. IMO- you gain nothing install air chambers in random spots
