A Guide To Fixing A Leaking Radiator
There aren't many things that can go wrong around the house that are equally annoying as finding a patch of wet carpet or a puddle of water around the lesser of a radiator – okay, maybe puppy training runs it close. . .
Simply puppies aside, in this blog we'll look at how yous can fix a leaky radiator and minimise whatsoever damage to carpets and floorboards.

How To Find The Source Of Your Radiator Leak
Have one of your towels and completely dry out the surface of your wet radiator.
This will give y'all the chance to discover the water leak – information technology's very difficult to find the source of any leak if the radiator is totally saturated.
Once your radiator is dry you should exist able to isolate the source of the leak quite easily.
Take some toilet tissue and systematically check each fixture (or union) on the radiator one-past-i: this should help you to understand where the leak is coming from.
Is A Radiator Leak Serious?
Radiator leaks can be serious. Particularly when the heating is on and the water is hot! Information technology is of import to plow the heating off before attempting to fix a leaking radiator.
H2o from a leaking radiator can also seriously damage laminate floor, causing it to swell and warp. If plenty water sinks into the boards it can as well dissolve the glue that holds them together and pull them apart.
Even durable hardwood floor can be in need of repair and show stains if a radiator leak is absorbed by the porous wood. Not platonic considering the expense of ownership new wooden flooring or trying to protect precious original boards!
Carpets are also at risk from h2o damage. It but takes 24 hours for mold and mildew to build up if the carpet is sat in water and can exist very hard to clean.
In addition to potentially creating a home decor nightmare, leaky radiators tin also create bug for your banality. Leaks decrease the pressure level in your heating arrangement over time and can crusade the banality to shut down. Cheque if your boiler force per unit area if right with the assistance of our guide.
What Can Crusade A Radiator To Leak?
Radiator leaks tin be caused by various issues and come up from one of three places:
- The body of the radiator itself.
- The bleed betoken, valve or tail.
- The piping that fills the radiator with water.
The almost mutual trouble that causes a radiator to leak is a fault with the radiator valve. Try the method below to fix your leaking radiator valve.
Is Your Radiator Valve Leaking?
A leaky radiator valve is normally i of the easiest types of leaks to set.
A leaking valve normally occurs when the spindle packing contained within the valve starts to article of clothing out or becomes damaged.
This type of leak will normally occur when the valve is in a 'mid-open' position – the leak will normally terminate when y'all fully close the valve.
How To Fix A Leaking Radiator Valve
- Drain the system – To repair a leaking rad valve you volition first have to drain down the arrangement to below where the leak is occurring.
- Close the valves – Plow off both the supply valve (where the water enters the radiator) and the lockshield valv east (the plastic capped valve at the other side of the radiator) – call up to count how many turns information technology takes to close the lockshield valve.
- Protect the flooring – Become your towels and bucket ready to catch any remaining h2o that may escape from the radiator.
- Loosen the nut – Using an adjustable spanner, disengage the union nut (the i between the feeder pipe and the radiator).
- Bleed the radiator – Open up the bleed valve to allow the residual of the water to leave the radiator and go into the basin.
- Tape up – Starting at the male end of the valve tail, wrap carefully with PTFE tape between x-15 times.
- Open the valves – Re-tighten the union nut and open the bleed and lockshield valves (remembering how many times you turned it before to shut it).
- Shut the bleed valve – When the water is restored to the arrangement, re-bank check for any leaks and then close the bleed valve.
Practise you need to supercede a radiator valve?
Before replacing a radiator valve y'all'll accept to purchase a replacement : preferably the same blazon every bit your existing valve – a different kind may not properly align with the water pipe in the same manner.
One time you have a new valve you'll need to drain all of the water from your cardinal heating system . Unscrew the nuts connecting the water pipe to the valve and so unscrew the valve to supercede it.
Make clean the threads at the stop of the radiator before installing the new valve.
Wrap PTFE tape around the threads of the new adapter (meet above) and screw it into the end of the radiator, be sure to not overtighten and damage the fixing.
Slide the valve cap-nut and a new olive over the terminate of the pipe and connect the new valve.
Once the new valve is in place you'll need to refill the system and bleed your radiators to remove any air.
Be certain that you advisedly check the site of the fitting for whatsoever leaks.
Tips on replacing and installing a radiator valve can be found in the video below.
Is Your Radiator Leaking From The Spindle?
A radiator with a damaged spindle – that's part of the connection between the pipework and the radiator – can sometimes exist the master cause of a leak and thankfully, information technology's hands remedied.
Using a spanner, tighten the gland nut and come across if the leak subsides. If this fails, disengage the nut and current of air some PTFE record downwards into the spindle (see below) before tightening back upwardly.
If this yet doesn't finish the leak, you may have to drain down the system and supersede the valve –failing that, it's probably a skilful idea to call a plumber.
Is The Radiator Valve Or Gland The Cause Of The Leak?
Often, a leak at the radiator valve coupling nut tin oftentimes exist fixed by just retightening the coupling.
If this fails, yous'll demand to supplant the olive inside the coupling.
To do this you lot have to drain the heating system of h2o and then loosen the nut between the leaking pipe and the radiator.
Remove the nut and the fitting and take the olive off the pipe and supplant with a new one – smearing with silicon sealant or winding it with PTFE record earlier reconnecting. If this doesn't work so you lot volition probably have to supercede the radiator valve altogether.
How To Repair A Leaking Radiator Gland
Sometimes you may find that your radiator is leaking from under the plastic cap of the valve – the gland.
If this is the case, it can be fixed quite easily with PTFE tape.
- Firstly, turn off the valve
- If the water is however coming out of the radiator from under the plastic cap, you will need to plow off the lockshield valve at the other end of the radiator
- Remove the plastic cap and gently unscrew the gland nut with an adaptable spanner, taking care to not harm the nut.
- Stretch a length of PTFE tape (nearly 20cm long) into a cord and wrap it around the spindle of the valve – that's the fiddling flake sticking upwards.
- Using a modest apartment-headed screwdriver, force the PTFE tape into the torso of the valve.
- Use a little silicone grease to the tape and screw the gland nut back on tightly.
- Finally, supervene upon the plastic cap and turn the valve back on.
Is Your Radiator Leaking Considering Of Corrosion?
As with everyone and everything everywhere, stuff gets quondam – and your radiators are no dissimilar.
The main culprit of radiator corrosion is sludge building up within your rad and effectively causing it to rot from the inside out – this kind of radiator leak is more ordinarily known equally a pinhole leak.
Sadly there isn't really any hope of 'fixing' a leak caused by corrosion, just at that place is a temporary measure you can take.
If you have a feed and expansion tank – 2 water tanks in your loft that maintain the level of h2o in your system – adding a plastic resin sealant will stalk the catamenia until you can purchase a replacement radiator.
Note – Y'all must Non use this type of sealant in a sealed central heating system!
If your radiator is corroding and a leak occurs, regardless of any temporary measures you lot take, you will have to go a new radiator: thankfully, we stock a few .
When you have replaced your leaky old radiator with a shiny new one, be sure to add together a rust and corrosion inhibitor to the water; this will ensure that the problem doesn't pay you some other visit a few years downward the line.
How To Repair A Leaking Pipage Joint
In a mod key heating organization compression valves are normally used to join the pipes to the radiators.
If ane of these joins springs a leak, it is possible to perform a quick fix by tightening the valve with a spanner.
However, if this doesn't solve the problem and the leak persists, you can perform the following bit of maintenance –
- Drain downwards the system to beneath the source of the leak.
- Take a spanner and disengage the nut at the joint of the leaking pipe and pull the pipe free.
- Where the face of the olive meets the joint, wrap a couple of turns of PTFE tape effectually and then re-tighten the nut.
And If You Don't Set up Your Leaky Radiator?
Regardless of what y'all do, sometimes information technology's best to call in the professionals and get them to exercise the leak fixing for y'all.
The final matter you want to practice is make a small-scale problem worse by fiddling with something that yous shouldn't.
