A lot of times, all it takes is tightening up parts like valves or couplings to stop the leak. Other times applying glue or sealant where it's leaking does the trick,' explains Matthew Ferris, a master plumber and the founder of <a href="https://www.ferrisplumbingheating.com/" rel="nofollow" target="_blank"> Ferris Plumbing </a> .

Look for cracked joints or degraded tubes, as these are all common leak points. Thoroughly clean the area around the leak to accurately assess the damage. </p><h3 class="article-body__section" id="section-2-turn-off-the-heating-system"> 2.

'This should help stop the leak, although it may not stop immediately. </p><nbtemplate data-id="AdPlaceholder" data-content="JTdCJTdE"></nbtemplate><p> Give it some time for the pressure to drop low enough.

'Make sure to drain the water to a point below the leak to prevent further water from escaping.' </p><nbtemplate data-id="AdPlaceholder" data-content="JTdCJTdE"></nbtemplate><p> 'You’ll need to stop the flow of water into the radiator by closing the lockshield valve, which is usually found on top of the valve, under a little plastic cap,' explains Sean Richardson. 'Use a pair of pliers to turn the valve clockwise, stopping the flow. Then, you can drain the radiator. </p><p> 'Put down some towels and a basin large enough to handle the water capacity of your radiator to catch the water as it drains. Once the water is drained, turn off the water supply valve to stop the radiator from filling while you work on it.' </p><h3 class="article-body__section" id="section-4-apply-epoxy-or-sealant"> 4. Apply epoxy or sealant </h3><figure class="van-image-figure inline-layout"><p class="vanilla-image-block"><img src="https://img.particlenews.com/image.php?type=thumbnail_580x000&amp;url=0Isi0A_0qbqcD2H00" alt="https://img.particlenews.com/image.php?url=0Isi0A_0qbqcD2H00" width="1125" height="750" ></p><figcaption class="inline-layout">(Image credit: Renaissance At Home) </figcaption></figure><nbtemplate data-id="AdPlaceholder" data-content="JTdCJTdE"></nbtemplate><p> If the leak is coming from the radiator tank or a small crack in the radiator body, there are a couple of temporary fixes you can try. </p><p> 'Apply <strong></strong> epoxy putty or sealant <strong></strong> to plug minor leaks or cracks,' advises Shlomo Cherniak. 'To do this, clean and dry the area around the leak thoroughly. Knead and apply epoxy putty according to the manufacturer's instructions. Allow it to set fully before turning the heating system back on'. </p><p> For this task, we like to use a <a href="https://www.amazon.co.uk/dp/B07VYR629M/" rel="nofollow" target="_blank"> Janolite Epoxy Putty Repair Stick, from Amazon </a> .&nbsp; Allow the epoxy or sealant to cure completely before refilling the radiator, and remember this is only a temporary fix - the radiator may eventually need replacing. </p><p> If the leak persists – or if it's a larger hole or crack – you should consider using a <strong></strong> commercial radiator stop leak product, such as <a href="https://www.walmart.com/ip/Bar-s-Leaks-Radiator-Stop-Leak-2X-Concentrate-6-oz/1843538843" rel="nofollow" target="_blank"> Bar's Leaks radiator stop leak from Walmart </a> . These products can be poured into the cooling system to seal the leak.&nbsp;However, it's important to follow the instructions provided by the specific product you choose.

'Simply tighten the nuts on the valves attached to your radiator with a spanner – if this sorts the problem, job done.' </p><p> 'If that doesn't work, you may need to replace the valve,' explains Shlomo Cherniak. 'To do this, you'll need to discharge any water, cut off the water supply, and turn the lockshield valve. You can then replace the valve yourself or call a plumbing expert for assistance.' </p><p> To replace the valve yourself, Josh Mitchell advises: 'Remove the valve carefully, noting how it was assembled. Replace the old washer with a new one of the same size and type. Reassemble the valve and turn the water supply back on, making sure every link is secure.' </p><h3 class="article-body__section" id="section-6-refill-and-bleed-the-radiator"> 6.

'You’ll also need to open the bleed valve to get the radiator refilled, so make sure you have your valve key handy.' </p><p> When water (not just air) starts coming out, close the bleed valve. This removes trapped air, improving the efficiency and heat distribution of your radiator. </p><h3 class="article-body__section" id="section-faqs"> FAQs </h3><h3> When should you call a professional to fix radiator leaks? </h3><p> Don't hesitate to seek professional help when fixing radiator leaks if: <br><br> - You are not confident in your repair skills. </p><p> - The leak is substantial. </p><p> - The radiator is very old and/or rusted </p><p> - The system shows signs of extensive corrosion or damage. </p><hr><p> Once you have fixed any leaks, turn on the heating system and monitor any signs of new leaks.
