If you have brass shutoff valve inserted into a hose that carries salt seawater, is it subject to galvanic corrosion? Should it be bonded, or would it be OK?
Here's the situation. I have 3 air conditioner system on my boat. They are fed by a single raw water pump, with individual supply lines coming off a manifold. When it comes time to winterize it is difficult to isolate each line to ensure AF is in each system. The hoses are tough enough that clamping with a soft jaw pliers doesn't work well.
Adding in a valve for each line to be able to shut 2 loops while one remains open would seem to be solve the issue. Ideally I would use a 1/4 turn PVC ball valve with barbed fittings. The issue is I can't seem to find a combination of PVC valve and barbed fitting to match the 5/8" supply hose. There are plenty of 5/8 brass ball valves readily available, however. Hence my question - I would not want to have the brass valves rot out and leak from galvanic corrosion. I'm just not sure if they would need to be bonded for a "proper" install.
