Greenhouse use. 1.5HP 15GPM Berkeley submersible pump 200' down installed last year. No control box or Amtrol tank, just turn on/off through breaker switch and water goes directly to garden hose.(I know, not optimal set up...lol) Currently has a 100 PSI relief valve installed on manifold at top off well casing.
We water our plants by standard hose, lengths run 250-300'. When watering with 1 hose only, the pressure will build up over 100PSI, so we usually run a second line into a holding tank and keep PSI around 90. Watering the plants with 1 hose at 90 PSI ,the pressure out of the 250-300' hose is really good for our needs, but we would like to know if we could go higher on the PSI and not have to run a second line to lower pressure below 100 PSI.
First question, I assume running at 90 PSI is ok? Secondly, how high on the PSI can we actually go to not do damage to the pump? If we can run higher PSI, I would set relief valve higher, or get a new one.
Last question, when a relief valve is triggered, can it still be used? I ask because the valve was working last year, but I recently had PSI go over 100 and the valve did not open.
Any input appreciated, thanks.
edit: pump manual states this:
Shut off head: feet-403, PSI 174. Is this relevant to my questions?
