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.

    Absolute pleasure to deal with. They installed our new toilets with care. They removed and disposed of the old as well as leaving the bathrooms clean. They also returned a few days later to check their work and if we were happy with them. Very happy to refer them to others.

    Had a very positive experience with Doherty Plumbing. Easy to book, scheduled conveniently and on the day George went above and beyond to do a great job and go the extra mile with cleaning up. Very happy and would definitely use again.

    George came; did my work quietly and respectfully. Noted a problem (big gaping crack in the pipe under the bench), and asked if we would like to change it. No pressure applied, and just added it to his list when I gave the go ahead. Would use this company again and again.

    Expected attendance time was managed well with calls and alerts prior to. People were respectful, friendly and professional. Problem was quickly diagnosed, fixed and tested through appliances. Clean-up afterwards was greatly appreciated and a step above other service providers. Used Doherty a number of times, very happy to recommend them.

    The team from Doherty Plumbing responded promptly to my emergency call to unblock the sewer drain in our backyard. Tim and Angus were professional, courteous and thorough in their work. I highly recommend this business to take care of your plumbing issues.
