Your expansion tank is the cheapest part in the system. It’s also the one that kills pumps.

A well expansion tank holds an air cushion so your pump doesn’t have to start every time someone runs a tap. When the cushion goes, the pump takes the beating — and a tank replacement is a fraction of a pump replacement.

Signs your tank is done

Any two of these together and the tank is the problem, not the pump.

Pump starts every time a tap opens

There’s no stored water left in the tank, so the pump is doing the tank’s job. This is the classic waterlogged tank.

This week

Tank feels heavy and sounds solid

It’s full of water with no air cushion. Either the pre-charge was never set or the bladder has failed.

This week

Water spits from the Schrader valve

The bladder or diaphragm has split and water is on the air side. A split tank can’t be re-charged — it needs replacing.

This week

Rust streaks or weeping at the base

Tanks rust from the inside out at the bottom seam. A weeping tank is close to letting go, and they fail with a lot of water.

Same day

Air bursts from the taps

On a failed bladder, the air side and water side have connected. You’re getting the cushion delivered to your kitchen.

Same day

It’s the original tank and the house is 15+ years old

Bladder tanks typically run 8–15 years. An original tank on a well that’s had pump trouble is living on borrowed time.

Three steps

How the visit goes

We test the tank before we condemn it

Pre-charge reading, drawdown measurement and a bladder check. A tank that only needs air gets air — we’ll tell you if that’s all it is.

Flat price, your approval, then the swap

Tank, fittings and disposal in one number, quoted before work begins. Most replacements are a single visit.

Bigger tank, fewer pump starts

We size up where it makes sense, because a larger tank means longer run cycles and far fewer motor starts — which is what actually extends a pump’s life.

What Simcoe County well owners say

“Freddy was amazing. He took his time to carefully diagnose the problem, making sure he fully understood the issue before moving forward. His professionalism and attention to detail were clear throughout the entire process. Once he identified the root cause, he had it fixed within an hour, working efficiently without ever making us feel rushed.”

“I called PHD for a leak in the basement and they sent Jimmy over within an hour. While he was here he noticed a second leak and saved our sump pump from flooding the basement. Fantastic service, very friendly and quick. Would definitely recommend!”

FAQ

Expansion tank questions

How do I know if my well expansion tank is bad?
Three quick checks: tap the side of the tank — it should sound hollow near the top; watch whether the pump starts every single time you open a tap; and press the Schrader valve on top — air should come out, not water. Water at the valve means the bladder has failed.
How long do well pressure tanks last?
Usually 8–15 years. They fail sooner when the pre-charge was never set correctly, or when the water is high in iron, which is common on Simcoe County wells.
What size expansion tank do I need?
It’s matched to your pump’s flow rate and the run time you want, not just the size of the house. A 32-gallon tank suits most family homes; larger households, livestock or irrigation want 44 gallons or more. We size it on site.
Can a waterlogged tank be repaired?
If the bladder is intact, it can be drained and re-charged, and that fixes it. If the bladder has split — water at the air valve — there’s nothing to repair and the tank has to be replaced.
Will a bigger tank make my pump last longer?
Yes, and it’s the most under-rated upgrade on a well system. Pump wear comes from starting, not running. More stored water means fewer starts per day.
Is this the same as the expansion tank on my water heater?
No, though people use the same words. Your well expansion (pressure) tank stores pressurised water for the whole house. A thermal expansion tank on a water heater absorbs the expansion of heated water. We service both — just tell us which one you’re looking at.
What does it cost to get someone out?
Diagnosis is free — finding the fault costs you nothing. There is a $45 service call on weekday visits. Evenings, nights and weekends carry a higher call-out rate, and you’ll be told that number when you book, not after. Once we know what’s wrong you get one flat price for the repair, and nothing starts until you approve it.
What does the 10-year warranty cover?
Major parts are warrantied for 10 years for customers on our maintenance program — keeping the system serviced is what makes that coverage possible, so the program is a condition of it. Equipment also carries its manufacturer’s warranty. Ask us what the program includes and what it costs before you decide.
