A faulty hot water cylinder can quickly become stressful, especially if it's leaking, making noise, overflowing, or leaving your home without hot water.
At ARQ Plumbworx, we inspect the entire hot water system, identify the cause of the problem, and clearly explain the best repair options before carrying out any work.
We help with common hot water cylinder problems, including leaking pipework, faulty valves, tempering valve issues, low hot water pressure, loss of hot water, overflowing relief drains, water hammer, noisy pipework, and older cylinders that may require repair or replacement.
Where possible, we repair the problem rather than recommending unnecessary replacement. However, if your cylinder is badly corroded, split, unsafe, or no longer economical to repair, we can advise you on suitable replacement options.

Common hot water cylinder problems we repair
Leaking hot water cylinder
Water around the cylinder can come from pipework, valves, fittings, the drain tray, or the cylinder itself. We check the source of the leak and advise whether it can be repaired or whether the cylinder needs replacing.
Poor hot water pressure
Low hot water pressure can be caused by old pipework, valve restrictions, pressure reducing valves, low-pressure cylinders, or blocked strainers.
No hot water
No hot water may be caused by an electrical fault, thermostat issue, element failure, valve issue, or a problem with the cylinder setup. We can inspect the plumbing side and advise if an electrician is also required.
Tempering valve problems
A faulty tempering valve can cause water to be too hot, too cold, or inconsistent. We can inspect and replace tempering valves where required.
Overflowing or dripping relief pipe
A constantly running overflow or relief drain can point to a faulty valve, pressure issue, or expansion problem. This should be checked before it causes water damage or higher water bills.
Old or corroded cylinders
Older cylinders can start showing signs of rust, corrosion, leaks, or poor performance. We can assess whether repair is worthwhile or whether replacement is the safer long-term option.
Our hot water cylinder repair process
1. Inspect the cylinder and valvework
We check the cylinder, visible pipework, valves, overflow, drip tray, water pressure, and signs of corrosion or leaks.
2. Find the actual cause
Not every leak means the cylinder itself has failed. Sometimes the issue is a valve, fitting, pipe connection, or pressure problem.
3. Explain your options
We explain whether a repair is suitable, whether parts need replacing, or whether the cylinder is no longer economical to repair.
4. Carry out the repair
Once approved, we complete the repair using suitable plumbing materials and workmanship.
5. Test the system
We test the system after the repair and check for leaks, safe operation, and correct function.
Repair or replace your hot water cylinder?
Many hot water cylinder problems can be repaired, particularly when the fault involves leaking pipework, valves, fittings or temperature and pressure controls.
However, if the cylinder tank itself is leaking, badly corroded, split or unsafe, replacement may be the more practical and cost-effective solution.

Hot water cylinder repair FAQs
Can a leaking hot water cylinder be repaired?
Yes, depending on where the leak originates. Leaking pipework, valves, fittings and tempering valves can often be repaired or replaced. However, if the cylinder tank itself is corroded or leaking, replacing the cylinder is usually the safer, more practical option.
Do you repair hot water cylinders in East Auckland?
Yes. ARQ Plumbworx provides hot water cylinder repairs, valve replacements and fault diagnosis throughout East Auckland, including Howick, Botany, Pakuranga, Cockle Bay, Highland Park, Bucklands Beach and surrounding suburbs.
Why is my hot water cylinder overflowing?
A continuously overflowing relief drain may indicate excessive water pressure, a faulty relief valve, a problem with the expansion control system or another system fault. A plumber can inspect the valves and pressure controls to identify the cause and recommend repairs.
Why do I have no hot water?
Loss of hot water can result from an electrical fault, thermostat or heating element failure, a faulty valve, or problems with the hot water system. ARQ Plumbworx can inspect the plumbing components and arrange for electrical faults to be investigated by a licensed electrician where necessary.
Can you help with tempering valve replacement?
Yes. ARQ Plumbworx diagnoses, repairs and replaces faulty hot water tempering valves throughout Auckland.
A faulty or blocked tempering valve can cause fluctuating hot water temperatures, reduced hot water flow or water that is too hot or not hot enough.
We inspect the valve and associated plumbing to identify the problem and recommend a suitable repair or replacement.

When should I replace instead of repair my hot water cylinder?
Replacing your hot water cylinder may be the better option if the tank itself is leaking, badly corroded, split, unsafe or no longer economical to repair.
However, problems involving faulty valves, leaking fittings or pressure controls can often be repaired without replacing the entire cylinder.
ARQ Plumbworx can assess the problem and explain whether repair or replacement is the most practical solution for your home.
