Is your boiler heating your domestic hot water if so i would turn water off to water maker and see if your boiler pressure stays down below 20 psi. If so water maker is bad. The other thing that could cause this problem would be the boiler pump is out.

If the water heater is leaking you have a rusted tank and it needs to be replaced. Turn off the water till it can be replaced. No fix for a rusted tank has to be replaced.

SOURCE: central heating circulating pump
The vent pipe should be in front of the pump so that the pump pushes towards the vent pipe NOT sucks from it. I hope this vent pipe is part of the heating system and not of the hot water
Pumps like to push not pull and therefore it is better if the pump is located further down - say at the bottom of the cylinder or lower.
With an indirect cylinder, the hot water & heating are separate circuits and are not and must not be interconnected. You will need a separate pump for the hot water which should be taken from the hot pipe coming out of the cylinder. You may get vacuation in the cylinder - then you will need an Essex or similar valve to replace the hot water outlet connection
By the way - The pressure at any hot tap is directly related to the height difference between the tap and the header tank in the loft [thus a shower downstairs feels stronger than one upstairs]

first off ensure water is getting to boiler, next, No pilot = pressure switch. On my baxi solo 40 pf pressure switch is replaced 8-10 times a year cures your problems,,,,,,,, momentarily , and have had all your other parts,but with no effect to speak of,.......sorry............ solution = [ change boiler ].sounds like gas pressure or lack of water to system or **** boiler like mine .........good luck.
