SOURCE: my jet pump has a 20 - 40 pressure switch but

There are several causes for this to occur.
1. If it is a 20-40 switch right out of the box it may not be set correctly. I have had this happen. If it builds to 30psi and shuts right off without straining to build to 40psi adjust the Cut-Out pressure up to 40psi. There are two different adjustments on a well switch. One for Cut In / Cut Out psi and one for Cut Out psi.
2. Lack of head pressure being built by the pump can be the cause. This can be attributed to the wrong Jetting in the pump. IE: A shallow well jet/venturi on a deep well.
3. The pump may have a bad impeller, but the pump will generally really strain to build pressure and a bad impeller will be loud, like grinding at times.
4. Double check the pre-set pressure in bladder tank also.

SOURCE: 1/3 hp shallow well jet pump (mastercraft brand).

I don't think the power shortage had anything to do with the pump, I think it is the impeller or a gasket, or both. It is hard to say, a pump like that should **** dry and pull water right in.If you put your hand over the end of the pipe, it should make a mark like an octopus on your hand. I would take off the impeller, look for trouble, and replace 3 or 4 parts in there , you should have water. Hope this helps.

I have a UtiliTech 1/2 HP Jet pump #0003124. I need a manual. Can I get a larger volume impeler for this mode?l


Put a vacuum gauge on the suction, see if it goes real low after pumping a couple of gallons. If so, your point may be stopped up. A 1/2 hp pump should pump 40/50 psi, fill a 5 gal bucket in a minute or so.

Why does my pump loose pressure


Sounds like your not using enough water, and or your pipes to sprinkler is to to small, causing pump to build up to cut off head. I cant lay my hands on a performance chart for your pump, but 60 psi cut off and 20 on sounds about right. Try running another tap when your sprinkler is running, and see if this keeps your pump running

Can the pressure switch on the Utilitech 1hp convertible shallow well pump be changed from 20/40 to 30/50?


Yes, if the plumbing can handle the extra pressure. There should be a nut in the middle of a large spring inside the pressure switch. Turn that nut clockwise to increase the pressure. You may need to run some water to keep the pump cycling while you do this.

How do I tell the pump to shut off when up to pressure?


The black cover on the side is the pressure switch. Open it you will see two screws with springs on them. Don't touch the short one. The tall one will adjust the pressure. Clockwise for more, counterclockwise for less. Cover should have diagram.

I have a utilitech jet pump can only set pressure to 20-40 would like to set to at least 30-50 but cannot .The pump is less than 6 months old .any ideas other than i bought the wrong brand


Sorry Richard,
Sounds like you are correct, you bought the wrong type of pump...if your looking for pressure/output you might consider purchasing a "sprinkler pump"...they will go past 70psi and more

I have a utilitech convertable pump. It is used as a shallow well pump at the moment. It worked fine untill last week, the hot water tank went bad and we replaced the tank and all the above ground lines....


Hi mid_age_elf
Your problem is that your "water bound"...
Your water tank must have a cushion of air for the pressure switch to work properly.
Turn off your pump and drain about 1/3 of the water from your tank.
Once you have an "air cushion" the pump and switch will work properly.
You can also add air pressure using an air compressor and an air valve installed on the top of your water tank or maybe on the side or bottom of the tank.
You would put air into the tank until about 1/3 of the water is gone replaced with the air.
Once that is complete your problem will be solved.

I have a Utilitech 1hp shallow well jet pump which turns off and on rapidly while using water. I have 25 psi in the air tank. I replaced the pressure switch and still have problems.


Good you got it working. Please post again if you have more trouble on this or another item. Also be sure and check what I mentioned just in case you are operating at the margins, don't want a failure right after you got it going!
