Hot Water Cylinder Repair – What You Need to Know

If your shower feels like an ice bucket or the tap dribbles lukewarm water, the hot water cylinder is probably the culprit. In Taunton, a broken cylinder can ruin a morning routine fast, but you don’t have to panic. This guide walks you through the most common issues, simple checks you can do yourself, and why calling a local pro saves time and money.

Common Causes of Cylinder Failure

Most hot water cylinders fail for three main reasons: corrosion, scaling, and a broken thermostat. Over years of use, tiny bits of metal inside the tank rust away, creating holes that leak. Hard water leaves lime deposits on the heating element, which makes the tank work harder and eventually overheat. A thermostat that can’t read the right temperature will either shut the heater off or keep it running nonstop, both of which waste energy and can damage the unit.

Another frequent offender is a faulty pressure relief valve. When pressure builds up inside the tank, this valve should pop open and release steam. If it sticks, the cylinder can burst – a scary scenario you definitely want to avoid.

Age matters too. Most cylinders last 8‑12 years before parts start giving up. If yours is older than that, start budgeting for a replacement even if it’s still working.

DIY Checks Before Calling a Technician

Before you pick up the phone, try these quick steps. First, locate the power switch or circuit breaker for the cylinder and turn it off. This protects you from electric shock while you inspect.

Next, look for visible signs of a leak. Check the pipe connections at the top and bottom of the tank, and drag a hand around the base for any moisture. A small drip may be easy to fix with a new seal, but a large puddle means the tank itself is compromised.

Feel the water coming out of a hot tap. If it’s rusty or has a metallic taste, the inside of the cylinder is corroded. Also, listen for odd noises – popping or clicking usually means lime scale is gathering on the heating element.

If the pressure relief valve is the suspect, carefully lift the small lever on the valve (with the power still off). Water should flow out without pressure. No flow indicates the valve is stuck; replace it before the tank cracks.

Lastly, check the thermostat. Many cylinders have a dial you can set a few degrees higher or lower. If the water temperature doesn’t change, the thermostat is likely dead and needs swapping.

When any of these checks point to a serious problem – especially leaks, stuck valves, or obvious corrosion – it’s time to call a professional. A qualified Taunton repair technician will safely drain the tank, test electrical components, and replace parts without risking further damage.

Choosing the right service matters. Look for a local company with certified engineers, transparent pricing, and quick response times. A reliable shop will also offer a warranty on parts and labour, giving you peace of mind after the fix.

In most cases, a simple part replacement – like a new thermostat or pressure valve – restores full hot water in a few hours. More extensive damage, such as a corroded tank, may require a full replacement. Even then, modern cylinders are more efficient, so you could see lower energy bills after the upgrade.Remember, regular maintenance helps avoid emergency repairs. Flushing the tank once a year to remove sediment, checking the anode rod for wear, and keeping the area around the cylinder clear of clutter are all low‑effort tasks that extend the unit’s life.

So the next time you’re left shivering under a cold shower, run through the quick checks above. If you spot a leak, strange noises, or a stuck valve, don’t wait – call Taunton’s trusted hot water cylinder repair specialists. Fast, affordable service is just a phone call away, and you’ll be back to hot showers before you know it.
