@Captain Larry-DH , I too leave all the pump lines disconnected, sorry I didn't describe the whole process in detail. I have a dock water fitting on the stern that accepts city water pressure right to the water manifold. I'm pretty sure city water pressure can be near double the 60 PSI of air I put into the system and is usually at least 80 PSI so I'm pretty comfortable with the pressure I use although you are right that it well exceeds the pump pressure. Once you open any faucet there is an instant drop in the pressure on the system. At any rate it's been working fine for me with no plumbing issues but if anyone is nervous about it most compressors have an output regulator that is easily adjusted.
