Water Tank
Expansion, Pressure & Storage Tanks
Highland Village Plumbing installs and repairs the tanks that keep a home’s water system steady: thermal expansion tanks on water heaters, pressure tanks on private wells, and storage tanks for backup or rainwater. A failing tank shows up as pressure that surges or drops, a well pump that switches on and off too often, a dripping relief valve, or leaks around the fittings, and each of those gets worse the longer it is left.
Our plumbers size the tank to your system, set the air pre-charge correctly and connect it with the right valves, so it protects your pipes, fixtures and equipment. Whether you need a failed expansion tank replaced, a waterlogged well tank diagnosed or a storage tank tied into your plumbing, we handle the work across Highland Village, TX.

Frequently Asked Questions
Water Tanks FAQ
What does an expansion tank do?
Water expands as a water heater warms it. In a closed plumbing system that extra volume has nowhere to go, so pressure rises on the pipes, valves and the heater itself. An expansion tank holds a cushion of air that absorbs the extra water, which keeps the pressure steady and stops the relief valve from dripping.
How do I know if my expansion tank has failed?
Tap the tank. A working tank sounds hollow near the top, while a waterlogged one sounds solid all the way up. Other signs are a water heater relief valve that drips, pressure that jumps when the heater runs, and water coming out of the air valve on the tank.
What are the signs of a bad well pressure tank?
The most common sign is short cycling: the pump turns on and off every few seconds while a tap is open. You may also notice pressure that pulses at the faucet, a pressure gauge that climbs and falls quickly, or rust and moisture on the tank.
Why is my water heater relief valve dripping?
A dripping temperature and pressure relief valve often means pressure builds up when the heater runs, which a failed or missing expansion tank causes. It can also mean the valve itself is worn. Either way, have it checked: the valve is a safety device.
How long does a pressure tank last?
Tank life depends on water quality, pressure settings and how often the pump cycles. Checking the air pre-charge during routine maintenance and fixing short cycling early are the two things that help a tank last longest.
Can I replace a water tank myself?
Some homeowners can, but it means draining the system, setting the tank's air pre-charge to match your water pressure and making watertight connections. A mistake can flood a utility room or damage a pump or water heater, so most people have a plumber do it.
What size expansion tank do I need?
It depends on your water heater's capacity and your home's water pressure. A plumber checks both and matches the tank to them. An undersized tank will not stop pressure from building, and an oversized one costs more than it needs to.
Do I need an expansion tank on my water heater?
If your home has a closed plumbing system, for example because of a check valve or pressure-reducing valve on the main line, you usually need one, and many local codes require one when a water heater is installed. We can check your system and tell you.
Why does my well pump keep turning on and off?
Rapid on-and-off cycling usually means the pressure tank has lost its air charge or its bladder has failed, so it can no longer store water under pressure. A faulty pressure switch can cause it too. Left alone, short cycling wears out the pump.
Which type of water tank is best for a home?
It depends on the job. Expansion tanks protect water heaters in closed systems, bladder-style pressure tanks suit private wells, and polyethylene tanks are the usual choice for above-ground storage. We recommend a type once we know how the tank will be used.
How much does it cost to replace a water tank?
It varies with the type and size of tank, how easy it is to reach, and whether piping or valves need replacing at the same time. We inspect the system and give you a price for the job before any work starts.
Do storage tanks need to sit on concrete?
Not always, but they must sit on a firm, level base. A concrete pad suits large tanks and soft ground, while compacted gravel or a rated platform works for many smaller tanks. An uneven base stresses the tank and can crack it over time.
