I have just bought a house with a 85 ft. deep well with submersible pump
It appears that there is also a underground pressure tank. I have never heard of this. can anyone shed any light on this subject? P.S. There is also
an underground sprinkler system. and we could not find any above ground
pressure tank in the house or crawl space.
Thanks in advance Merle

I had an in well pressure tank, the particular model I had has a 50% failure rate. (according to the well guy). Just had it pulled about a month and a half ago and had an above ground pressure tank installed. Fortunately for me it was still under warranty; although I did have to pay for labor for them to pull the old and install the new.

I have a 5" well 105 feet deep.

I want to make it clear I do not believe all in well tanks have such a high failure rate, it was just my model. I do not know the model of the tank they pulled.

The sprinkler system does not need a separate pressure tank. A friend of mine actually had his system installed prior to the tank so he had full pressure going to his system. That way he could run more heads at the same time.

A few years ago, there was a well pump system (sold as an energy saver, of course) that had a very small pressure tank, or no tank at all. It used a VFD (variable frequency drive) to control the speed of the pump motor in response to changes in system pressure.

A lot of hype, fast-talking salesmen, etc., the only one I've ever seen actually installed was a dismal failure. Lots of pressure surges, as well as equipment failures. This system is now a basic above-ground pressure tank with a normal pressure switch and control box.

I haven't heard anything good about in-well pressure tanks either.

If the system works, I would leave it alone until something fails, then have a viable plan to go to a normal pressure tank system.

Thanks for the input. I have found out that the pressure tank is buried in the ground. and was told by a well driller that this is common. and if it works ok fine, when it stops he suggested moving the pressure tank into the crawl space under the house. at least you can look at it and if need be replace it without tearing up the lawn. Again thanks for the inputs. This site is one of the very best I have ever belonged to.

You must live down south. My water line is buried six feet deep to prevent it from freezing in the winter. :yes:


If it is buried in the ground do they put a protective shield around it or just cover it up with dirt?
