Hi guys, hope everyone is keeping busy.
Just want some clarification on what pressure the safety valves should blow off at? Currently it is going off between 125-130psi and settles back down at 120psi. Should it be going off at 120psi and dropping down to 110psi? What tolerance am I allowed.
Kind regards
Luke Crowther

The pressure should not go more than 10% above set point with a good fire and the steam blower on, ie worst case conditions.  Quite a worrying time the first time it is done!!
