I seem to have a couple of weak services on the same circuit, I'm thinking ARV may need replaced or adjusted. Any guides I've found are removing the valve and hand pumping in a test block. Wondering if its possible to just break into the circuits and test pressure here. Its the kinda job ill never do again, already bought the pressure gauges to adjust main relief but reluctant to buy more kit for a one off job. Is there any reason this is normally done on a test jig?
