Send Over-Pressure Shore Water Over the Side with Pressure Valve ?

I have a 75 lb over pressure valve not hooked up yet.
I was thinking to put it into the shore side line with a tee so if the pressure was too high, it would release the pressure and send it overboard.
I think it used to be setup to vent into the bilge.

How many situations would you find where marina water pressure was that high?
I never have, they all seem rather low and weak pressured.

Re: should I send over pressured shore water over the side with pressure valve?

A shore side water pressure regulator/reducer should limit inlet water pressure to 35 - 45 psi, and have a built-in backflow preventer.

Oh your right, I forgot I do have a regulator, I think taco branded.

I have this overpressure valve which I dont know why it was ever put on the boat.
It used to be plumbed into the hot water heater, YET that heater also has the temp pressure relief valve some maybe it was leftover from a prior owner.
I saw the same valve at Lowes in the well water pump section and it had a pressure rating of 75lb.
So perhaps it has no value or use on the boat anymore.

You must be filthy rich if you can dump water over the side. Marinas I know charge per gallon and it is not cheap. Get a pressure regulator from an RV store.
