The shallow well jet pump is 10'-0" from discharge hose bibb. the suction line from the well to the pump equalizes at the same pressure as the tank. I am suspect if there is an internal check valve that is stuck open.Is there an internal check valve?

There should be a check valve or foot valve at the bottom of the line to prevent water from running out of the well pipes. If this valve is stuck open, then there will be no pressure in the line and no water coming up to the pump.

Pump will not shut off


could be worn mechanical parts in the pump, or air in the pump. Make sure there is no air leaking into the suction/inlet side of pump.

Can i use a 1" suction an 3/4" discharge


Yes, Actually the larger suction will provide better water flow to the jets and help your pump operate more efficiently.

sounds like you still might have a leak. but in the short term bleed off 5 pounds of air from your bladder tank and the pump will turn off quicker. Your pressure switch my has a weaken a bit from age which would effect it turning on and off

My water system is loosing pressure. The pump runs until it gets to the preset of 50 psi but when it stops, the pressure drops right away. if I shut off the pump, it drops to 0 psi. I checked the pressure...


There is a screened check valve that should be attached to the pick up / suction side of the pump on the very end of the plumbing in the bottom of the well. If you have shut off the water output going to the home / what ever and the pump still drops pressure to zero as soon as it shuts off the shallow well foot valve is stuck open / has failed.

Some systems use both a foot valve and an in-line check valve to prevent the symptom you currently have.

Foot valve example:

More examples:

http://www.plumbingsupply.com/images/well-footvalve.jpg

If this valve has failed... there is nothing to prevent the contents of the pressure tank from dumping back into the shallow well.
I doubt you have a shut off on the pump suction side but if you do once the pump shuts off close this valve. I would bet your pressure tank holds the pressure. If you do not have a shut off valve... just feel for a rush of water in the suction pipe AFTER the pump reaches pressure and shuts off. If your feeling water flow with the pump off and the tank at pressure / loosing pressure the foot valve is bad.

Hello, Our Flotec Shallow well Jet is installed in our basement a distance ( perhaps 50 feet or so from the well casing outside in the yard. The pump was installed as a replacement for a worn jet pump...


Hi, Tom, W/D here.
You shouldn't really need a check valve as the foot valve is in effect a check valve.
Next time that you are near the pump when it kicks on and you are using no water, let it achieve full pressure and kick off. Close the discharge valve, isolating the pump and suction line. Watch the pressure gauge. If the pressure falls, you either have a leak in the suction line, possibly a leak at the well head (sucking air), a leak in the casing riser pipe or bad foot valve.
If the pressure holds steady, open the discharge valve and note the pressure. If it falls immediately upon opening the valve, the leak would be on the house side if the pump. Look then for any sources of water usage (ice maker, drips in the tub, water from the pop-off valve at the water heater, etc.).
Best regards, and good luck.
If I can be of any further assistance, please post back.

I have a model 109163. I'm trying to pump water from a creek. The suction hose is about 6 ft below the pump and 12ft long. The output hose is running about 300 ft at a gradual incline to about 10 ft. My...


In order for the pump to **** up water, it must discharge air. Try this. Install a hose bibb (faucet) in the discharge line over top of the pump. Fill the pump housing with water, turn on the pump and open the hose bibb/faucet until full water flow is established. Almost all air should be out of the pump and suction line at this time. Now when you close the hose bibb/faucet, the pump will have plenty of pressure to fill the long discharge line.
Suction line should be 2-1/2 inch if that is the pump suction size.
What size is your discharge line?
There should be a check valve/foot valve on the end of the line in the creek to keep water in the pump once it is primed.

Pump cycles like crazy!!


Sometimes a new tank the blatter will be kinda sealed to the sides of the tank.the amount of air in the tank s/b equal to the cut in pressure of the pressure switch.(40 lb) that would be (60 lb) cut out if you messed with the little screw on the pressure switch you have a problem.there must be the 20 psi of differance between start and stop.

Installed a new jet pump for shallow well (gravity feed to pump) - used old pressure tank - after about 4 months pump began kicking on and off constantly when in use - troubleshooting guide suggested it...


The pressure tank must have a certain amount of air in it so pump doesn't cycle as you say. The new pressure tanks have a bladder that separates air from water and keeps the pump from cycling so much. Make sure your pressure switch on the pump is OK--ie doesn't have burned contacts!

Cabin pump, primed fine only goes to28psi and keeps running


Sounds like the injector nozzle is plugged. This nozzle is directly inside the influent line on single line jets and down in the well on two-line jets. I'm assuming you have it primed correctly. If this happened suddenly the it'd definitely the injector nozzle. It it was a gradual process over time then I would say it's either a badly worn nozzle or worn impeller.

Air in faucets


The tree may have damaged a pipe,which is letting air into the system. I'm suprised you haven't mentioned a leak. It's possible for air to be pulled in thru the motor seal, if suction is high. High suction usually means trouble in the well, a clogged point or a malfunctioning check. Push on pipes and the pressure line to the switch, if they leak water out, air can be drawn in.
