Plumberparts.co.uk, honest reviews and tips Hold tight! And welcome to today's Plumberparts.co.uk video that's all about how to remove And the airlock of the coolant If you have followed all the other steps that we have on our channel on how to get access You go radiator, you have done your TRV, then you have done balancing system, you have changed the pump Speed, you've done everything and it's still running you probably don't have to You find it's got airlock on going into that radiator or that chain of radiators if They still don't work if you have not all of those things you probably want to give First try them because you need reasonably good knowledge and steel balls To be able to actually do this a certain thing.
Click on the link so this is what appears now That will take you to thats HUB radiators got loads of all of the videos About radiators. Let's take a look at how we're going to remove this lock now. You're going to need a Hose. As I said you are going to need a big nerve! And after that Hopefully they can get moving and spot. Hold tight! So we did everything we could on this system and on this cooler It's still not getting hot Now this can also work for saying three or four rads that are not getting hot on some Leg, so always on hand to know how to do it.
So the first thing we do is be it in The pressure system or whether the tank it's feeding from the loft is that we turn off the valve on Every end. This is the first thing we do. Get yourself next Bleed the main coolant like this one. A little tip for you if you get one like this Get yourself a file and a file taper off because it gets really annoying. I put a little mark on mine up I'm not losing. Although I am probably still going to. A small Tupperware basin and possibly a piece of cloth And just dispel the pressure of the coolant. Right once you finish that drain and you have dissipated the pressure from the coolant Get a hose so it will go a normal hose size of 15mm like This one here For 1/2 inch male thread. Some radiators will have a built-in thread just for the nipple to bleed If you got it one of those you wouldn't be able to do so. So once you've got that ready. Get a little PTFE PTFEand get around it After that remove your nipple bleed screw into this take out of your hose.
Be right next to it I was on guard and then I take this off. It should come loose and be under a towel Something to catch a small amount of water As soon as this comes out you should be able to feel it if you tap it a little. OK that will come now and just loose Quick change a little over like that. See that? How fast was that? Like a cat! Even quick, I can't believe myself sometimes! If you don't think you've got a good enough connection between your faucet and your hose or nipple As we call it Get yourself a jubilee clip and wrap that round there to tighten up and that up. Before we move on to the next bit I recommend you turn all of your heating system off You go to either port two or three port fuses, and if you know how, latch Then open, you will find the little arm on there – the latch can only be opened.
Also if You've got a squeeze system Make sure you've got a reasonable amount of pressure in that natural home It will be one to one and a half bar If you need to know how to top the page, look at our site Pressure on heating video systems and also if you've got a tank fed from Loft make sure that the ball valve drops nicely down and has not been stuck in so that they can get in Sometimes stuck This will not allow more water into the system. Once you've done that, you are Ready to do the next bit cleansed by air From the flow side and all return coolant. What we're going now not Is the flush side You will not believe how easy this is to do. All you have to do is unlock The radiator is above. You'll hear air and water rushing out of this big hole we've now done Got here Instead of this tiny little hole you used to be here. I will let any that air out. Now if you sometimes have a heating system You could already turn on open this valve and feel the hot water coming through.
As soon as you feel the hot water coming through you are pretty much guaranteed that you have Probably removed the lock. Now hopefully this system here no longer has any airlocks in it. So we probably won't hear much of the air coming out But I'm going to open it anyway, and you never know what you might get. Hmm, I got a little in there! Turn it off looks like it has cleared now and it's very warm as well Thus we will not close that and then sign the other party. So we've closed that TRV at the other end and bled that little bit of air now and we're going to just do that Side shield lock.
A few drops of air there. That would come through nice and warm now, thats great. So right now we've been purging and flushing the opposite side of air. From the air We've got warm water coming through each of these ends. What do I need you to do right now Close each of these valves. The pressure will dissipate automatically from your hose So you don't have to worry about that. Remove your faucet, then put it back in your main bleed air. Once You have done so make sure that the system has either topped itself again up and f Tank E Or top it up with a special pressure ring like filling we described in our pressure Video heating. Before we finish because now you've likely successfully obtained your radiator gone I was happy Larry, and there are some things you don't need to think about why air I got in the system or in that radiator. One reason number is that there is enough not to mind in the system Mineral water will interact with radiators inside And create hydrogen. Cause number 2 and you've got an automatic air vent that is very close to suction The side of the pump can sometimes be tempted to suck air through an air vent.
The number of three tubes is your reason being expansion on the wrong side of the pump. Sometimes you'll be able to put your thumb on expanding tubes and see he's sucking on your The thumb. The fourth reason is to set the pump speed too high. Now it may sound crazy but if there is not Enough water is delivered to the impeller pump, that is, not enough Suction. Then the different pressures between suction and side discharge The pump impeller is such that the water causes the ability to cavitation. If you want to know more about cavitation just go online because I can not be bothered Go into it now but all you need to know is that it does not create air and that It can create airlocks. So make sure the pump speed is in the correct setting.
