My Legal Dilemma?

Well, unless you asked the seller specific questions about the house he did nothing wrong. "Wrong" is too vague and too subjective. "Wrong" to you might not be "wrong" to someone else.

Also, unless you put your questions in writing and answered in writing, even if you asked the seller about the lack of water pressure, there is probably nothing you can do. Verbal commitments to questions/answers mean nothing.

Is this tank a municipal water tank? I can't believe the original builders would have been allowed to build close enough to the tank that the water pressure would be negatively affected. Normally, there are building codes and permits that have to be issued and followed to insure problems like this don't occur.

I guess the only thing you can do if talk to a lawyer about your problem. Most will discuss a problem for free and then decide if the case is worth pursuing. If it is most lawyers will only charge you if you were to win.

You also might want to research a higher quality pump with a good warranty. No matter what the conditions, if the manufacturer states the pump's abilities and operational guidelines and you stay within them it shouldn't be burning out so often. If so, then any problems you receive from the pump should be covered under the manufacturer's warranty. Or get a better one with a better warranty so you don't have to keep spending money over and over and getting the same results.

I hope my answer helps you out!

You need to check on statute of limitations first of all. Second, what proof do you have that the sellers not only knew there was a problem, but that IT WAS A PROBLEM? Some people don't think low water pressure is a problem, they just think it varies from house to house, etc. I know my mom's house has much lower water pressure than my house and there is no problem with the pipes, pumps, etc. Just different houses, different place.

ONE MORE THOUGHT: if you can prove that the builders were told not to build there for whatever reason, maybe you have a case against the builder instead.

The statute of limitations on most civil suits is 2 years, so you'd need to file right away. Based on the limited information you gave, it sounds like you might have a case. Try your local Yellow Pages and look for lawyers that give free initial consultations. They'll be able to tell you if you have a case and whether it's worth pursuing.
