BurCam Pressure Issue

Having a pressure issue here, if any one has ideas.

First, nothing was wrong.
Then we had a power outage.
Now, the pump will cycle on in spurts continuously while you have tap on, giving very little pressure.

BurCam Model 506121S

Using it as a pump from a PolyTank, we don't have a well.

Any Ideas??

Your pump is a 1/2 HP shallow well jet. If it is near the level of the plastic tank it should pump about 12 GPM at 30 PSI.

It seem like you have lost prime. You may have some air in the suction pipe.

Is there a check valve or foot valve in the tank?

Is there any high spot in the pipe between the plastic tank and the pump? If there is, it probably has an air bubble. That kind of bubble will restrict the flow from the suction to the pump.

The usual practice is to have the inlet pipe from the suction point always slope upward a little bit so any bubble will travel from inlet to pump.

If there isn't much lift you might be able to pull the bubble out with a wet-dry shop-vacuum.

Hmmmmm

Well, pump is over 4 feet below the tank, so I can't see it being a problem there.

We replaced the switching mechanism, and have checked the foot valve, and all seem to be ok and it still is not working right.....

Do you have any other ideas maybe??

If the pump is 4 ft below the tank then there can be an air bubble in the pipe, especially if there is a check/foot valve.

Lines running down hill can be among the hardest setups to prime because it is hard to get the air out of the suction pipe.

If the pump is below the tank, and the suction pipe doesn't have to go over any high spots, then that is one case where it is often best to remove the foot valve and put a check valve at the pump. If the check valve is on the discharge side then you must move the pressure switch sensor line of the pressure switch to the tank side of the pressure tank.

If the pump is below the source, then you should be able to prime it by merely opening a valve at the discharge of the pump to let water run through. If you can't prime it that way then you have a bubble in the suction line.
