Water manifold/pressure/repair options?

[Jenjones]

We recently installed a slightly stronger water pump and since then we’ve had both the hot water outlet to the galley and the hot water outlet to the swim deck shower blast off the water main manifold. What are our options to remedy this?
Currently we just have those two hot water valves closed.

In the absence of any details whatsoever, I have to assume that you had hoses come off their fittings. Put them back on, use proper solid band hose clamps, and tighten them down hard.

This is not rocket science.
