You're getting a Westford house ready to list, and the basement holds a pump, a blue tank, a gauge and maybe a second pump nobody can explain. Buyers and inspectors will ask about all of it. Before listing, find out what each piece does and who is qualified to vouch for it, and change nothing until then.
One boundary up front: Jeneral Plumbing doesn't repair, replace or remove well pumps, pressure tanks, pressure switches or other well equipment. That work belongs to a well contractor, with an appropriately licensed electrician for the wiring that serves it. We can assess indoor plumbing and treatment connections. Ask the Health Department and your laboratory who may collect the sale-compliance sample. This guide shows how those pieces fit together so each question reaches the right person.
Confirm where the water comes from
Westford has both town water and private wells, according to the town's private-well information, so start with the address, not the neighborhood. A water bill from the town points to public supply. Well records, a well cap in the yard, and a pump and pressure tank in the basement point to a private well. The town's annual drinking water quality report describes the public system only; it says nothing about the water, pump or tank at a private-well property.
What the basement equipment does
On a typical private well, a pump moves water from the well into the house. It may be a submersible pump down in the well or a jet pump in the basement. A pressure tank stores water under pressure so the pump doesn't have to start every time someone opens a faucet. A pressure switch starts and stops the pump as pressure falls and rises through a set range. From there, water passes through any treatment equipment and into the home's piping.
Configurations vary, so treat that description as orientation, not a diagnosis. Photograph each label, model and serial number, and where each pipe enters and leaves. Note where the electrical disconnect is, but don't operate it.
Leave the "extra" pump alone
A second pump, an extra tank or a valve nobody remembers is a reason to investigate, not to disconnect. The equipment might be active, abandoned, bypassed or serving a purpose that isn't obvious at a glance. Unplugging a pump, closing an unfamiliar valve or cutting piping as a test can cut off water to the house, start a leak or erase evidence the well contractor needs. Ask the contractor to trace what's active first. If something turns out to be abandoned, the well contractor defines the pump and tank work and coordinates any required electrical removal with an appropriately licensed electrician. Any plumbing change left inside the house gets its own licensed scope.
Westford's water-testing rule for a sale
Massachusetts has no single statewide testing mandate for private wells, though a lender or local board of health can require testing, according to MassDEP's private-well testing guide. Westford has its own rule. The town's linked Water Supply Regulations, checked in September 2026, call for a laboratory report when a property with a drinking-water well is sold or transferred. The sample must have been collected and analyzed within one year of the closing date, with the required sampler credentials and chain of custody.
Confirm the current procedure with the Westford Health Department and your closing professionals before scheduling a sample; the town's rule controls, not this summary. Jeneral Plumbing doesn't issue that report or interpret the transaction. Water that looks and tastes fine isn't proof of safety either, which is why the EPA's private-well guidance points owners to certified laboratories. Keep every report whole, with its date, sample location and whether the sample was taken before or after any treatment.
Who answers which question
| Question | Who answers it |
|---|---|
| Is the pump, pressure tank or pressure switch working properly? | A well contractor |
| Are the pump's wiring and disconnect safe? | An appropriately licensed electrician, coordinating with the well contractor |
| Does the water meet the town's sale requirement? | A certified laboratory, with the Westford Health Department on procedure |
| Are indoor pipes, shutoffs or treatment connections leaking? | A licensed plumber |
| What must be disclosed, and what does the buyer's lender need? | Your agent, attorney and lender |
Keep each finding attached to the part that person looked at. A receipt for a filter repair doesn't vouch for the pump, and a pump invoice says nothing about water quality.
Where Jeneral Plumbing fits
Low pressure, a drip at a filter housing or a wet spot near the tank can come from a valve, a clogged filter, a fixture, indoor piping, the tank, the controls or the pump itself. We evaluate the accessible indoor side, including supply piping, shutoffs, unions and the connections at treatment equipment, and our pipe leak repair service covers confirmed leaks there. When the evidence points to the pump, tank or controls, we'll tell you it's a well-contractor call rather than guess.
On the water side, our water testing process explains the difference between field checks and the certified-laboratory analysis that a sale requirement or health question needs. If results show a problem worth treating, our test-first water treatment service starts from those results, and sometimes the right answer is no new equipment.

Call (978) 392-7789 to talk through the plumbing side of your pre-sale list.
Does low water pressure mean the well pump is failing?
Not necessarily. Low pressure can come from a partly closed valve, a clogged filter or aerator, a treatment stage, the pressure tank, the controls, the pump or the well's yield. Write down where and when it happens and whether it affects hot water, cold water or both. Don't adjust the pressure switch or add air to the tank as an experiment. A well contractor diagnoses the source side, and we can check indoor piping and treatment restrictions.
