+ Hot water cylinder leaking:

  • The issue could be with the cylinder, valving and/or pipework.
  • If the water is dripping from the overflow pipe call the SEAL Team. A slow drip can waste a surprising amount of water if you don’t act promptly.
  • If water is dripping from the base of the cylinder or from pipe entries call us to see if the unit is repairable.

+ Water pressure too low:

  • If you are on tank water check your filters are clear.
  • If you are on mains supply, make sure your isolation valve is fully open at the mains.
  • If these easy fixes don’t work call the experts at SEAL Plumbing & Gas Services to get it sorted. We can offer various options to suit you needs and your budget.

+ Water temperature too high:

  • It may be an electrical fault with the thermostat. Alternative you may need a new tempering valve, call us for assistance.

+ Excessive water bill:

  • You may have a faulty water meter but most likely a leak. SEAL Plumbing & Gas Services can advise the nature of your problem. The leak may be in the pipe from the meter to the house (i.e. the “water main”) and/or within your house. Whatever the source you need to act.
  • The SEAL Team can often detect leaks in buried pipes and once located, excavate and repair them. If, however, there are multiple leaks or the pipe is too deep it may be best to run a new water main. We will discuss the options and prices before undertaking any works.
  • If the leak is in your house, we can help locate and remedy the fault. Usual culprits are toilets that run on, taps or cylinders that leak. Some issues are easy to fix while others are more involved. Call us for advice and a free quote - we are happy to help.

Natural Gas:
