Long Island Well Pump Repair & Replacement: Pumps, Tanks & Switches
Most of Nassau and western Suffolk run on public water, but head east and the story changes. Across the East End, the North Fork, and plenty of pockets of eastern Suffolk, from Wading River and Calverton out through Riverhead and beyond, homes draw every drop from a private well. When the well pump quits, there's no water for showers, toilets, laundry, or the kettle. Nothing. All Island Comfort has been repairing and replacing well pumps, pressure tanks, and pressure switches on Long Island wells since 2004, and we're based in Wading River, right in the heart of well country.
We handle the whole pump side of your well system: submersible pumps down the well, jet pumps in the basement, pressure tanks, switches, check valves, wiring, and control boxes, along with all the residential plumbing the well feeds. Family-owned, licensed and insured, and never subcontracted.

A house with no water is an emergency, and we treat it like one. Check your breaker first. If that's not it, call us. No-water calls get same-day dispatch across Long Island, day or night.
Call 631-591-2289How a Long Island Well System Works
If you've never had to think about your well before, here's the two-minute version. Four parts do almost all the work, and when your water acts up, one of them is usually to blame:
The Well Pump
Most Long Island wells use a submersible pump: a cylinder-shaped pump and motor that hangs on a drop pipe deep inside the well casing, pushing water up to the house. Older or shallower wells sometimes use a jet pump instead, which sits in the basement or a well house and pulls water up by suction. Submersibles are quieter, more efficient, and handle deeper wells; jet pumps are easier to reach but limited on depth.
The Pressure Tank
Usually a blue or gray tank in the basement. It stores water under air pressure so the pump doesn't have to fire up every time someone rinses a glass. A healthy tank means long, easy pump cycles. A waterlogged tank means the pump hammers on and off constantly, and that's the most common well problem we see.
The Pressure Switch
A small box, usually near the tank, that turns the pump on when pressure drops (typically around 30 or 40 psi) and off when it recovers (typically 50 or 60 psi). When the switch sticks, burns its contacts, or its little sensing tube clogs, you get no water or a pump that won't shut off.
Check Valve & Foot Valve
One-way valves that keep water from draining back down the well when the pump stops. A failed check valve makes the pump cycle when no one is using water. On jet pump systems, a clogged or leaking foot valve makes the pump lose its prime, so it runs but moves nothing.
Everything in your house is downstream of these four parts: every faucet, toilet, the washing machine, and the water heater. When the well system struggles, the whole house feels it.

Well Pump Diagnosis & Repair
Good well work starts with an honest diagnosis, because the fix for "no water" ranges from a $50 part to pulling the pump. We check the cheap stuff first, in order, and show you what we find:
Pressure Switch Replacement
The single most-replaced part on any well system. Burned contacts, a clogged sensing tube, or a stuck lever will kill your water even when the pump is fine. Fast, inexpensive, and always worth ruling out first.
Pressure Tank Replacement
A waterlogged tank is the most common culprit behind pulsing pressure and short cycling, and it quietly murders pumps by making them start hundreds of extra times a day. We replace failed tanks with properly sized bladder tanks, set the air precharge to match your switch settings, and check the whole system before we leave.
Submersible Pump Pull-and-Replace
When the downhole pump fails, we pull it: pump, drop pipe, and wire all come up out of the casing. We inspect everything on the way up, then set a new correctly sized pump. Most residential pulls are finished the same day.
Jet Pump Repair & Replacement
Lost prime, worn impellers, leaking seals, failed motors. We repair jet pumps where repair makes sense and replace them when it doesn't, and we'll tell you plainly which side of that line yours is on.
Wiring & Control Box Service
Submersible pumps run on buried wiring, and three-wire setups add a control box with a start capacitor and relay that fail more often than the pump itself. We test and replace control boxes, capacitors, and pump wiring, which has saved more than a few homeowners from paying for a pump they didn't need.
Check Valves & Drop Pipe Issues
A failed check valve, a cracked drop pipe, or a leaking pitless adapter connection can mimic a dying pump: pressure bleeds off overnight, the pump cycles with no water running, output drops. We find leaks in the column and fix them at the source.
Well Pump Replacement: Sized Right, Built to Last
A well pump isn't a one-size part. The right pump depends on how deep your well is, how far down the water sits, and how many gallons per minute your household actually uses. An oversized pump short cycles and wastes electricity; an undersized one leaves the upstairs shower gasping. We size every replacement to the well and the house:
- Well Depth & Water Level: Determines the lift the pump must overcome and how it's set in the casing.
- Flow Rate (GPM): Matched to your fixtures, bathrooms, and irrigation load.
- Horsepower: Typically 1/2 to 1.5 HP for Long Island homes, chosen from depth and GPM, not guesswork.
- Quality Brands Only: Goulds, Grundfos, and Franklin Electric, the major names in well pumps.
- New Check Valve & Fittings: Replaced with the pump, so an old valve doesn't shorten a new pump's life.
- Manufacturer Warranties Apply: We install to spec so your pump's factory warranty stands behind the work.
One thing we don't do: drill wells. Well drilling and new well installation are a separate trade. If your well itself has failed or run dry, we coordinate with a local well driller and handle everything from the pump onward, so you still have one number to call.
No Water Is an Emergency. We Answer Like It Is.
When a boiler dies you put on a sweater. When a well pump dies you can't flush a toilet, wash a dish, or give the kids a bath. That's why no-water calls on well systems get emergency priority: same-day dispatch, trucks stocked with pressure switches, tanks, and fittings, and 24/7 emergency response across Long Island. On the East End and North Fork especially, where the nearest water main might be miles away, we know there's no plan B. Call 631-591-2289 any hour.
What Well Pump Work Costs on Long Island
Every well is different, so honest pricing starts with a diagnosis, not a number pulled from thin air. The main factors that move the price:
- Pump Type: A basement jet pump swap costs less than pulling a submersible from deep in the casing.
- Well Depth: Deeper wells mean more drop pipe, more wire, heavier pumps, and more labor to pull and set.
- Pressure Tank Size: Larger tanks cost more but cycle the pump less, and often pay for themselves in pump life.
- Access: A wellhead in the open lawn is quicker than one buried, landscaped over, or tucked in a crawl space.
- Parts vs. Full Replacement: A switch or control box is a small job; pump plus tank together is a bigger one.
- Wiring Condition: Old or damaged pump wire discovered during a pull is replaced while the well is open, not after.
You get a written estimate before any work starts. No hidden fees, no surprise add-ons at the invoice.
