Well pump replacement

How long should a well pump last?

A properly sized submersible pump commonly runs somewhere between eight and fifteen years. The spread is wide because the things that shorten a pump’s life are all avoidable: a waterlogged pressure tank that makes it start far more often than it should, sand and sediment wearing the impellers, a pump oversized for what the well can deliver, and voltage problems at the panel.

If your last pump did not last, the useful question is why. Replacing it without answering that buys you the same result again.

Submersible or jet

Most Northeast Florida residential wells run a submersible pump, which sits down the well and pushes water up. Jet pumps sit above ground and draw water up, and they are limited by depth. Which one your property has, and which one it should have, is decided by the depth of the well and how much water the household needs.

Sizing it properly

Getting this right means matching the pump to the depth of the well, the static water level, the yield the well can sustain, and the demand from the house, including any irrigation. An undersized pump will not keep up. An oversized one draws the well down faster than it recovers, runs dry, and destroys itself doing it.

• Well depth and static water level
• Sustainable yield of the well
• Number of fixtures and simultaneous demand
• Irrigation load, which is often what an original pump was never sized for
• Available voltage and wire size to the wellhead

What we replace at the same time

When a pump comes out, the check valve, the wiring splice and the pressure switch are all accessible and all cheap relative to the cost of pulling the pump a second time. If they are near the end of their life, replacing them now is the economical decision, and we will say so rather than leaving you to find out.

What we do and do not do on wells

We service existing wells. We do not drill new ones. Pumps, pressure tanks, the switches and wiring that go with them, water testing and inspections for a sale — that is our work, and it sits under the same licence as the septic side. We do not sell or fit water treatment equipment.

Drilling a new well is a different trade with a different licence, and we will say so rather than take the job and subcontract it. If that is what you need, call anyway and we will tell you what you are looking at before you start ringing round.
