Tips about how to stop leaking radiator by Joe an emergency plumber London. Joe explains ways to identify and fix leaking radiator within the home.

Before you can stop a radiator leaking, you must firstly find the area of the radiator that is leaking. Joe mentions that due to the amount of experience that he has experienced over many years at fixing leaking radiators as an emergency plumber London, it is very important to remove the water with a dry cloth to identify where the water is slowly coming from. Experience and common knowledge says this can be a number of things for an emergency plumber in London.

With major water leaks, identifying the problem is easy; most water leaks from radiators are small and often start as small drips, but within time the water leak from the radiator will get larger. To find the affected area of the radiator leak, firstly dry all wet areas including radiator valves, pipes and bottom of the radiator with a towel. Take some paper towels and in turn press each of the valves, visible pipe and the radiator itself. This will help to show the source of the leak on the radiator.

Top 5 causes of  how to stop leaking radiators

  • Radiator glands on the radiator valves.  This can happen if the valve has not been opened for a few months (common leaks on old radiator valves).
  • Corrosion is the effect water takes on the metal over time that can effect joints, valves and the radiator itself.
  • Radiators have at least three valves. Leaks can occur due to disturbance, failure, or corrosion.
  • Disturbing or knocking a radiator, which can disturb the joints or in some cases cause the radiator to fall.
  • The compression joints that connect the pipe to the valve are a very common source of leaks.
  • Builders and even DIY enthusiasts need to remove or relocate the radiators. This disturbance can cause a leak as the joints settle.

A competent DIY person can do most repairs.  However if you are in any doubt at all, it is advisable to call an emergency plumber such as Joe from London who can help. If the leak is coming from the radiator itself, it is more than likely going to need replacing. You can carry out a temporary repair with plastic resin filler as long as the area is dry from any damp residue. Be aware when doing cheap DIY jobs on a radiator as the time and effort is better spent replacing the radiator.

To replace the radiator which was leaking, turn off the valves making sure that the TRV has a blank on it, just in case it is to self-open. Now you can remove the valves from the radiator and lift away. However keep in mind it is very important to be careful because this may result in calling someone like Joe an emergency plumber London. Clean the threads with wire wool before fitting the valves to the new radiator and always check the security of the radiator and any joints for leaks. HINT: Never use PTFE to wrap around the threads when tightening the union nut to the radiator valve to save any complicated leaks. Either the spindle or the union nut is the cause of most leaks from valves. First, check the tightness of any nuts on the device. If this does not help with the leak from the spindle, it may require replacing.  The union nut connection may need a little more attention. Drain the radiator of water, remove the fitting and replace the olive (brass O-ring). Before fitting, wrap the olive in PTFE tape, tighten, and refill the radiator. Placing PTFE on the olive will ensure a snug fit and a watertight solution. Fitting a complete new valve is a last resort as most radiator valves can be fixed. Ensure the radiator is empty, undo the nuts and remove the valves from the radiator. When fitting the radiator, it is always important to make sure that you use the same fittings or they may not line up. Clean all the threads making sure to replace all the olives and wrap all with PTFE tape. Having refitted the valves to the radiator securely, the radiator will now require bleeding.

Joe an emergency plumbing London hope’s that the information above will help to stop any further leaking radiators in the future. If you have any concerns, it is always best to get help from a professional.
