Help, need new pump?

I dont know much so please keep that in mind when I describe this.

I have a cabin on a lake. The water system is designed to pump water from the lake (about 380 feet away and 80 feet below, give or take) to 3 pressure tanks in my pumphouse where it is pressurized and fed into my home. Over the winter I had the main line in freeze and shatter. We replaced 140 feet of the line, the electrician said when the line broke the pump ran until the overloads popped and while he could get it going he said as soon as we put a load on it it would probably go. Sure enough it did, once the line was fixed we fired it up, air started to come out of hose bib next to pump house then the 50 amp breaker running the pump blew. My electrician said the pump was rated at 24 amps, 240v about 7.5 hp??? After it blew he tested amp draw which was about 160 amps which he said means it is in what he called a locked position. He said the pump should be replaced. It sits about 25 feet deep in the lake.

My questions:

What should I expect this to cost me? (guess best case worse case?)

What is a good pump?

I'm not sure why the Pump is that large, but you certainly don't need one that big. How about a 1/2hp Submersible Pump. That is all you really need.

bob...

I guess the pump is 5 hp. It feeds a pump house that is set up to ultimately feed 4 home sites.

Is this pump only for irrigation or is it to supply potable water?

How much water do you need for 4 houses?

A 5 HP 40 GPM Goulds 40GS50 is about $2000 at the site at the link.

That is probably more pump than you need.

If you are using it for household purposes, that is far more than you need. If you are irrigating with it, then you should plan on allocating time for irrigation one or two houses at a time so you don't need such a big pump.

You can get by with a 2 HP pump for potable and sanitary water for four households; maybe a 3 HP pump for irrigation with control of timing.

If you are supplying potable water for 4 households from a lake you should be filtering and disinfecting the water. Since you are the owner you would probably be liable if someone got sick (think crypto or giardia or some bacterial intestinal infection).

The standard for public water supplies is the EPA Surface Water Treatment Rule which requires 99.9% removal or inactivation of giardia and 99% removal of crypto. That requires both a filter and disinfection.

If you are having someone else do the job it will probably cost you twice the discount pump cost you find at that site.
