Most I have dealt with are 1 1/4 inch.

Can you elaborate on that please?
I'm no expert, but I know that sometimes, wrong pressure in tank and bad pressure switch can cause pump to cycle, as can a buildup of air in the system.
Before doing anything else, I'd highly recommend finding the lowest valve in the system. If lucky, it'll be a 1" or larger, quarter turn valve. Fill the system up, then open the valve to quickly dump the system. Oftentimes, air can enter a line and slowly build up. By venting(?) the system, you can not only get excessive air out of the line, but also any buildup of sediment that might be hanging in a low spot.

I just had a problem with my pump running on, There were two problems.
The pressure shut off was set too high and---
Calcium nodules had partially blocked the jet. I had to reverse flush the jet to blow out the nodules. The foot valve if it works will block water exiting the bottom of the pipe Works fine now and did not have to pull the pipes. I did not want to have to pull those.

Can't help you on thread size, but I had the same
issue and put a foot valve in line before the
pressure tank. I actually had a hole in the pipe and
it was draining out to the water level in the well.
Deep well 180' but static level was 15-30 down.
It will stop the cycling but a bit of air accumulated
sometimes.

Wrong pressure in tank or a bad pressure switch cannot cause a pump to cycle, there has to be a leak! A waterlogged tank can
make a pump cycle more frequently, but the pressure has to go somewhere before the pump can start. If there are no visible
leaks then it's between the pump and the bottom of the well. I had a similar symptoms with a submersible, and it was a
cracked fitting where the line connected to the pitless adapter, on the outside, I dug it up by hand, 7 foot 4 inches down.
When I was very young we had that problem and the jet had rubbed on the side of the casing until it wore through. Before

Our well near St Cloud MN was set up like that on purpose, with an excess air valve on the pressure thank, to eliminate hydrogen gas from the water system. When I installed a new pump I drilled a small hole in the check valve in the top of the pump so it would work properly. If you use a captive air tank in locations like that you will get bubbles of hydrogen gas from the faucet occasionally. On our water system at the cabin (submersible pump) I drilled the valve in the pump also, and have a check valve at the pressure tank, with a bypass line around it with a valve. Then when I winterize I can blow the water out of the line from the cabin to the well.

I'm confused....what is an ejector and isn't the "foot" valve somewhere near the bottom of the well?

Vic, we're not pulling the pump, just the ejector and foot valve.[/quote]
Sounds like a jet pump set up. Pump is topside, pressure line sends water down, ejector uses pressurized water to aid lift by venture principle, foot valve is normally below the ejector. The pipes need to be pulled up out of the well to get to the ejector and foot valve.

All of these that I have seen are one inch pipe flowing down and one and one quarter inch pipe flowing up. I have seen quite a few.

Interesting design! Don't know of any around here.
Some use a single pipe jet pump to draw water from a reservoir or shallow cistern but here it's mainly deep wells with the pump hanging at the bottom of the pipe.
My house well is 420 ft, poultry house well is 500 ft, both on 1 1/4" schedule 120 PVC pipe.
The guy that drilled both wells pulls the pumps when we have problems, he gives me a better deal if I help.
Take the lines apart at the top near
the pump and blow into them with
compressed air. A coupe of good
blasts and put it back together prime
the lines with water and bammo your
off to the races.have done it many
times on my parents well, we used to
pull the pipes when I was a young boy,
then I learned the trick with the air
compressor. Proving it worked cost my
dad a case of beer, he said it's too
easy to work. 15 minutes later he was
on the losing end of the bet lol.

I actually have a similer problem but it's methane that will accumulate... we were in a major coal producing area and methane does bubble out of the water. When we moved her we could accumulate the gas and light it off a glass of water in September / October.
Now I have a degassing cistern before the pressure tank.
Still can be nasty.

A single line suction with the pump above ground is limited to 32 feet depth with a perfect vacuum. A jet pump with two lines can go over 200 feet deep. That is why they were called "deep well" when they came out. They pump from much deeper. Of course we all know that submersible pumps make it possible to pump from two times as deep as as a deep well jet pump, but in the business the two line jet is still called a deep well system.
Here in west tn. Packer type deep well jet pumps were common some are still in use.the well casing is used for the down pipe 2". A 1" pipe inside the 2"
casing is the lift pipe. The ejector is small enough to fit in the 2" casing with a foot valve on the bottom and leather cups to seal the ejector to the
casing.leaking down could be caused by foot valve,leather cups, or a hole in the casing. If you see 2 pipes going down the casing you don't have this
type.

Also if the pump cycles without any water use it is leaking back down the well. If it cycles too often when using water it is low on air in the tank. Some have a Schrader valve to add air or you can drain tank then refill to trap air in or if there is a faucet close to tank and a shutoff valve down stream of faucet close shutoff and blow air in through faucet.

Papaw8, The type of tank that you describe is very rare these days, LOL. Years ago when I used to visit my parents I would check their heating system expansion tank because it would get water logged. Every six months or so I would shut the boiler feed off, drain the water out of the tank, then turn the boiler feed back on. Finally they had the boiler replaced and a new "modern" bladder tank was part of the installation. If you have a tank that you need to add air to periodically you should look into a bladder tank. The most common one is the Well Extrol made by Amtrol. If you put in one that has a capacity of over thirty gallons you will probably notice that your pump cycles less often which will extend the life of the motor.
