Sometimes it's not about how good of a job your fitters did but the unknown age and condition of the existing system piping you're tying into. There are times when a 200 psi test is all it takes to open up pinholes and create leaks. Now the owner looks at you as being responsible and you're on the hook for repairs and loss of their production or product if something gets wet.

If your guys did a good job, a 200 # test should not be a big deal. As they say choose you battles wisely.Jim AdamsSent from my Verizon, Samsung Galaxy smartphone -------- Original message --------From: John Irwin via Sprinklerforum <sprinklerforum@lists.firesprinkler.org> Date: 8/19/20 7:11 AM (GMT-07:00) To: sprinklerforum@lists.firesprinkler.org, Mark Phillips <philli...@pyebarkerfire.com> Cc: John Irwin <jir...@quickresponsefl.com> Subject: Re: Testing of existing systems I included this reference in my response.
