Low water Pressure on pump??

Greetings,

I just un winterized my 2015 Itasca Sunova. After refilling water tank and water heater, I then cleaned out my faucets and lines of the antifreeze using city water pressure. I switched over to pump operation and have very low pressure and the pump runs continually with out stopping. I am pretty sure I have removed all the air from the lines and I have checked to see that I have the valves all in the normal operating position. I'm stumped, any advise??

Thanks in advance,

Dave

Did you use your water pump to pull in the pink stuff via a short hose at the pump? Check the valve there. You can also disconnect the discharge pump hose, cap it with your thumb to close it off and see if the pump will then develop pressure. The water pressure should build as you 'prime' the pump and get rid of air in the suction line. It will pump water fine, but not air, so you gotta get all the air out of the pump. You can't hurt the pump by closing off the discharge for a bit.

Thanks, I will try that. I did make sure that the syphon line valve was in the correct position.

When that happens to me, it is usually that I left the tank fill valve on somewhat, and the water is circulating out of and back into the tank, robbing most of the pressure.

Did you close your Water heater By-Pass valves when you De-Winterized the MH? It could be that the Outside shower is actually on with the shower head off or you left the fill valve in the fill position vice city water position.

I've had the same situation (more than once). As Danhannah says, it's usually the tank fill valve is left in the 'fill tank' position.
