What's Included

Full Well System
Diagnosis & Service

We don't just swap the tank — we assess your entire system to make sure the new tank is properly sized and the root cause is fixed.

System Pressure DiagnosisWe test cut-in and cut-out pressure, pump performance, and tank pre-charge to identify the exact problem.
Correct Tank SizingWe size the replacement tank to your pump's draw-down capacity — not just whatever fits in the space.
Tank Installation & Pre-ChargeNew tank installed, properly pre-charged to match your pressure switch settings.
Pressure Switch InspectionWe inspect and adjust your pressure switch to ensure proper cut-in and cut-out settings.
Old Tank RemovalWe remove and haul away your old waterlogged tank — no mess left in your basement or utility room.
Full System TestWe run the pump through multiple cycles to confirm steady pressure and no short-cycling before we leave.

Why Keystone?

We Know Well Systems
Inside and Out

Well system work requires specific knowledge — we've seen every failure mode and know exactly how to fix them.

Fast Diagnosis

We identify whether it's the tank, switch, pump, or something else — so you're not paying to replace parts that don't need it.

Proper Sizing

An undersized tank causes the same short-cycling you started with. We size it right based on your pump specs.

Local Knowledge

We work throughout South-Central PA and understand the local geology, water quality, and common well system setups.

Quality Tanks Only

We install reputable brands with proper warranties — no off-brand tanks that fail in two years.

Same-Day Available

No water is an emergency. We prioritize same-day calls for well system failures whenever possible.

Upfront Pricing

You'll know the full cost before we touch anything. No surprise add-ons after the work is done.

Common Questions

Well Tank FAQ

Answers to the most common well system questions we hear.

The most common signs are a pump that kicks on and off every few seconds (short-cycling), water pressure that surges and drops, a pressure gauge that swings wildly, or water coming out of the air valve on the tank. Any of these symptoms warrant a call.

Sometimes — if the bladder is intact and the tank just needs re-pressurizing, it may be salvageable. But if the internal bladder has ruptured (which is common), the tank needs to be replaced. We'll tell you honestly which situation you're in.

A quality pressure tank typically lasts 10–15 years. Lifespan varies based on water quality, proper sizing, and whether the pre-charge pressure is maintained. Hard water and undersized tanks tend to fail sooner.

Yes — a pump that starts and stops constantly runs extremely hot and wears out much faster than normal. A submersible pump replacement is far more expensive than a pressure tank. Don't ignore a short-cycling pump.

We diagnose pump performance as part of our well system assessment. If your pump needs service or replacement, we'll let you know and can discuss next steps. Call us and we'll walk through everything you're experiencing.
