How does this maze of plumbing work lol

[cm2785]

Well— I installed an accumulator tank as spoken about in the other thread, and before I could get the hot water tank on I noticed the original 2006 Shurflo water pump seemed to be seeping water… so out everything had to come to get to it and in went a brand new Seaflo pump to match the accumulator tank… the funny thing is, once I got the old pump out I noticed the strainer cup was loose and it may have been the cause… it’s funny because everyone seems to line them up so they are right side up with the pump but then they are less than hand tight… I tightened mine hand tight and it’s partially upside down now but oh well.. anyway, my question is this… the plumbing that feeds the pump from the tank also ties in from the main inlet coming from the wetbay yet obviously the tank doesn’t get filled by it… is there a one way valve in that tank or line? I can’t see one…

I think I just figured it out.. maybe that line is from the fill valve in the wetbay and the other line is for city pressure and thus the water pump doesn’t see the city connection except for the outlet of the pump?

Backflow valve is in the pump head.

Flex lines to the pump from the fresh tank and from the pump to the city water hook up are to reduce noise and vibration from the pump to the rest of the RV.
