Fresh water tank

Hi Vanleigh Owners
We are down here in south Al. right now and had the misfortune to have to cut my city water off and turn valve to fresh water tank, after the freeze, turned valve back to city water and noticed I have a good water drip coming from fresh water tank overflow, tank filling back up, looking online it could be the water pump or the main water valve connection, anybody know if these parts are repairable or do you have to replace, Thanks
By the way it is on a 2020 Vanleigh Beacon 39FBB

Hey Spud,

We have the same year and model unit you do.

I’m thinking if you had the city water connected and you’re noticing the fresh water tank filling up and overflowing it could be due to a bad check valve on the water pump which is allowing the water past and into the fresh tank. The water manifold that directs the water flow in the wet bay could also be a source for the problem. If those Anderson valves aren’t lined up they might be allowing the city water to flow into the tank.

You could easily just switch the water source on the manifold between, City, Pump and Tank Fill and back to City and monitor if the fresh tank is still being filled. If it still is getting filled, you might need to check the water pump back fill valve. You can disassemble and clean the pump components out as that can sometimes help. If that doesn’t solve the problem the water pump might need to be replaced. You probably have the same water pump I have (ShurFlo 4008) and you can purchase those for under $100 on Amazon. Not a bad idea to keep a spare either.

As for the Anderson water manifold, those can be replaced and are bit more expensive than the water pump and a bit more complicated in the hookups. I just replaced my manifold due to a broken valve knob. I posted the information in this thread.
Busted water heater bypass valve

If you do opt to replace the Anderson manifold, you’d need to call Anderson to order the replacement as they don’t list the Vanleigh version on their website. They also won’t warranty the manifold even though it says a 5 year warranty. That warranty starts the day they made it not when you purchased the finished product. At least that what the Online Sales & Marketing manager told me last fall.

Good luck in the troubleshooting.

Hi Stuart
Thank you for the comeback, I am leaning towards the Manifold as it was always very stiff to turn and now rotates easily, but while i am in there will check the pump if you can dismantle it to check backflow valve, what gets me is the fact that since i have been doing this i have probably turned that valve 3 times. Again thank you for all your help

You’re welcome Spud. My valves were stiff to turn, with the bypass being stiffer. When winterizing last fall it snapped off, the other valve turned, but I couldn’t bypass the water heater.

I believe the Anderson water manifold is about $255 according to the sales contact I was working with. For the pump here’s a link to the manual which show the diaphragm location.
