Can anyone gime a contact number or web site for an inline sea-water pressure relief valve made by a company called Grimes in the southeast somewhere?

Thanks Nathan !!

Your welcome.

I just saw stainless marine's new strainer with high pressure relief valve built in...looks pretty slick.

Link to their new strainer

Stainless Marine does an excellent job and their strainer has a higher reserve capacity than most. Important with any stepped bottom or high flying boat! Imco will also build any size strainer and include a poppet valve when requested. Possibly any high flow check valve with a cracking pressure of 2 psi will work and not load the impeller excessively.

Check with Mikehtmsr24 on the board. He has some kind of water bypass from Grimes.
