Valve kit for low pressure

Machine Repairs

Hi all :blush:

One of my pumps has lost pressure, about 1000psi. In the past, I’ve bought a valve kit and it brings it back to like new again.

I just wondered, do the bottom set cause low pressure? I checked the top set and they were fine (last time the o rings were damaged/gone)

Yes - I can go back outside and pull the bottom ones off, but I just wanted to know if those ones, being on the low pressure side, could cause a drop?

I’d venture to say you need to be looking at HP pump seals rather than valves

When my check valves go out it cause a little loss in pressure, but I mainly get a pulsating water flow.
