How do I clear an airlock in my pipes? It is one of the most frequently asked questions. When the hot water side has absolutely great flow, but you turn it to the cold side, there is absolutely nothing, or you get a little splatter.
Let’s learn how you can solve this problem.
How Do I Clear An Airlock In My Pipes In The Loft?
First of all, jump up in the loft and go to the big tanks, the cold water storage tank. Remove any visible lids and check the water level inside. This is the first step in the process. How do I clear an airlock in my pipes starts here.
If there is no water in these tanks, then you’re sucking air into it. Make sure that the water level is really high. If the water level is high, then you know your ball valve is fine.
Clearing The Airlock in The Pipes
Check that your ball valve is working correctly and letting enough liters per minute into the tank. Make sure there’s a good flow rate into the cold water storage tank. Check the outlets to make sure there’s no scale buildup blocking the outlets. Put the lid back and the insulation.
Make sure you prepare your plumbing for winter because it would be much harder to deal with such issues.
How Do I Clear An Airlock In My Pipes With A Vacuum?
Grab yourself a wet and dry vacuum. It needs to be a wet and dry vacuum, and you need to remove the filter from within the vacuum. Plug your vacuum in like so.
Open the side that’s got the air locks, and open the cold on the basin tap all the way open. Put the end of your hose over the end of the basin spout and turn this on. Hold it there for about 20 seconds or a minute. What this will do is suck any air and water out of the system, dragging the air lock to this outlet.
When you can feel it suck just purely water into the vacuum, remove your hose and check to see if you have flow. Let it run for about another 2 minutes, or until all the splurges of water stop. You want a nice steady flow coming out the tap.
Open the bath taps, shower, and toilet to get all the air out. Try all outlets. If you leave a little bit of air in it can quite easily airlock again. That’s because the pipework goes up and down in the system, and you have a high spot where air gets caught.
If you don’t have any flow, this is a very stubborn airlock. Because the air is in such a difficult place in the system, you’re just not going to suck it through.
How Do I Clear An Airlock In My Pipes With Mains Pressure?
Connect from this main filling loop of the system a mains pipe all the way through to the basin tap of the cold side, or find this isolation valve and connect up the mains.
Turn it on to force mains pressure back up to the cold water tanks and force the air out the top. You’re going to hear the water gurgle through the system as you turn it on.
Turn the water back off to let the water settle and let the air rise back to the top before turning it on for another blast. You’ll hear a massive gurgle and then nothing. When it’s completely silent of bubbles, that means you have removed the air lock from the system.
Put everything back together as it was. Reattach this flexi, turn on this isolation valve, put this airator back in, and test to see if it’s worked. Turn it to the cold, and you have good flow. This is how I clear an airlock in my pipes.
