Frequently asked questions
How much does well pump repair cost?
A national average of $450, with most jobs between $300 and $600, a published floor of $150 and a ceiling of $1,500. Individual parts vary widely: a check valve, pressure switch or pressure gauge runs $150 to $200, a control box $300 to $600, a well injector $500 to $1,000, and a pressure tank replacement $800 to $1,500 or more.
Should I repair or replace my well pump?
For small parts, repair without hesitation: a $150 to $200 switch against an $1,800 average replacement is not a close call. It gets marginal above roughly $500, where a well injector at $500 to $1,000 overlaps entirely with a shallow-well jet pump replacement at $400 to $1,000. The factor the cost tables miss is that most of the labour on a submersible pump is pulling several hundred feet of pipe, and that cost is the same whether you change one part or the whole pump. On an older submersible, doing it once usually beats doing it twice.

How much does it cost to replace a well pump?
A national average of $1,800, with most jobs between $1,000 and $2,500. By type: shallow-well jet pump $400 to $1,000, deep-well jet pump $500 to $1,400, submersible $1,000 to $2,500, constant pressure $2,000 to $5,000, solar $1,500 to $6,500. The published $20,000 ceiling is a windmill system, not a conventional pump.
My pump switches on and off constantly. What is that?
That is short cycling, and it is almost always the pressure tank rather than the pump. The bladder separating water from air has failed, so there is no cushion left and the pump satisfies and loses pressure immediately. A tank bladder is published at $50 to $100 and a pressure switch at $25 to $100, so it is worth naming this symptom specifically when you call, because a contractor who hears it will bring the right parts to the first visit.
How much does sprinkler repair cost?
A national average of $250, with most jobs between $100 and $400. Head replacement runs $65 to $90, damaged wiring $60 to $100, valve replacement $70 to $300 and a broken pipe $150 to $400. The outlier is the backflow preventer at $450 to $1,700, which costs more than twice the published maximum for any other single repair.
Why does a sprinkler head cost so much to replace?
Because you are paying for the visit, not the part. A sprinkler head is a $3 to $30 part and costs $50 to $120 fitted. That is why batching matters: walk the system with the zones running, list every fault, and have them all done in one visit. Three separate call-outs for three heads costs several times what one visit does.
One zone of my sprinkler system has stopped working. What is likely wrong?
A single dead zone rules out the expensive causes, since the pump and mains supply would affect everything. Working cheapest first: the controller not signalling that zone, a failed solenoid on the zone valve ($70 to $300), damaged wiring between controller and valve ($60 to $100), a debris-fouled valve, or a broken lateral pipe ($150 to $400), which usually shows as a wet patch.
Do you cover drilling a new well?
No. The scope here is repair and service of existing wells, pumps and sprinkler systems. Drilling a new well is a different trade, with different licensing and a different cost structure entirely.
