Water pump running

[Russellvh]

Last couple of days, in N. Texas, the nights have been low 20’s but days up to 40+. Each afternoon I fill the fresh tank and we use the fresh tank for washing dishes etc. The last 2 or 3 times after filling the fresh water tank and switching to dry camp the water pump would just run continuously. Water to each sink would run but very low pressure. After a couple of hours the pump would finally stop and everything is back to full power. Until the next refill time.

Is this a problem or just normal air in line. Also, no signs of water anywhere or drips anywhere.

I would check you fill valves to ensure they are fully set to the position. These fill valves have anti-siphon check valves built in and could be back flowing. if this is the case it could explain why eventually it shuts off. The valve finally closes.

Do you disconnect your hose after filling? I have never experienced this in our coach but you could be getting air in the lines causing a partial vacuum lock preventing line pressure to build. Check all you fittings to make sure they are tight and not leaking.

Good luck please post what you find to clear this up. We all like to hear updates.

Thanks, after filling I do leave the city hose connected. I agree it’s probably air getting in the line somewhere. The pump eventually stops running and them everything seems to work fine until the next time I fill the tank.
