Fresh water tank

[Steeljag]

Just returned from three nice nights at Salt springs in Ocala. They have full hook ups there and i was connected to their water system. I noticed i had water dripping from my pet cock valve on my low drain point. Mystery is, I've never used my fresh water tank in two years of ownership.

I'm talking a steady....steady....drip. Turned off water to camper and within minutes the drip stopped. Somehow, water from city water hook up is finding its way into my fresh water tank !

Any thoughts on what would be causing this ?

Thanks in advance for any replies !

The check valve , part of your 12V water pump is defective. The purpose of this valve is to prevent city water from being fed back into your on-board water tank.

VTX-AL thank you for the reply.

Can you tell me where that would be located ? And is it a easy fix ?

It is internal to the pump in most RV water pumps.
Some models can be rebuilt. Cheaper ones just get replaced.

if needed
an inline check valve can be bought
at any landscaping supply store for around 2.50

That is true. Just be sure the M/F fittings are in the correct direction.
