Why is My Hot Water System Leaking?

It might be baffling to not know the exact cause of a water heater leak in your household or workplace. If you suspect a hot water system leak, you should contact Doherty Plumbing Solutions for assistance!

Leaving it until late could cause long-term damage to the unit itself, and even harm adjacent walls and flooring if the leaking water begins to accumulate. Slow leaks, which are not always promptly detected, can further cause irregular water flow from the hot water system.

So, before things snowball into a bigger plumbing issue, it is always advisable to act fast.

While some hot water unit leaks can be tackled with minor repairs, others might require a hot water heater replacement. In this case, licensed plumbing professionals such as Doherty Plumbing Solutions are there to help you find the best option.

What causes water heaters to leak?

Irrespective of any make or model of a hot water system, leaks springing from the unit could be due to one or more of the following causes:

  • Corrosion inside the tank resulting from the old age/overuse of a heater
  • Ill-fitting pipework, which might leave the unit’s supply lines loose
  • Damaged valves, including the pressure and temperature release valve (PTV) and expansion control valve (ECV), which help to keep the unit functioning optimally
  • Higher water pressure in the water mains, compared to the capacity of the heating unit

What to do if you notice a water heater leak?

If you find hints of a hot water system leak, take the following steps:

  1. Try to locate the source of the water leak.
  2. Turn off the water supply to the heating unit from the mains.
  3. Contact a professional plumber for peace of mind, and to gauge if you need a simple water heater repair or a full overhaul of the unit.

    Came same day as I called to fix broken tap that couldn’t be turned off (had to turn water off at mains to stop flooding). Third time I’ve used them within 12 months for different issues. Very helpful, professional staff and reasonable pricing. Highly recommended.

    Of the many plumbing services they offer, this is the second time I've engaged them for different types of work. James has been very helpful and efficient in scheduling a time for a roof leak repair. Very pleased that the work was completed promptly. Trust that they have addressed the issues at hand.
