I have to say, guys, you must be wary of constantly topping up the central heating. The reason is that you will dilute the inhibitor in the system, leaving inadequate protection from corrosion. It's really important due to the fact that water contains electrolytes and this causes electrolytic corrosion; depaending where different metals are on tge electromotive scale, superior metals will eat inferior ones, in this case the copper tube & brass in the valves, will eat the iron in the radiators and the heat exchanger in the boiler. Ultimately, you could end up needing to replace both the boiler and all of the radiators. Certainly, the system will fill up with magnetite, black sludge, caused by corrosion, which will slow down the time it takes to heat up and how much heat it gives out. It's bad. Using leak sealer usually works. I found this video as I was just looking for anyone who had used for a heat exchanger. The boiler is due to be replaced in the spring, so I'm just keeping it going over the winter for a customer. Anyway, the poster of this video didn't update, so I guess no news is good news?!? P.s. I am a plumber. I'm not keen on using leak sealer, and I think of it only as a temporary fix. Always best to find the leak, drain down, fix it properly. Leak sealer is guaranteed for 1 year which is good enough for what I'm doing. Hopefully 😊
@@georgeparkin4420 thank you for letting me know! I am not a plumber and was thinking of removing this video 😂 it did reduce the pressure from falling but now it falls over a longer period of time. Issue still not resolved however and have had 2 plumbers unable to find the problem! Not sure if it’s a pipe underneath the concrete floor in which case it will need to be dug up!

@@MimiS6000 are your radiators and pipe work all brand new? Or just the boiler? You can check if it’s the boiler by isolating the heating otherwise best to get your plumber in to check if there are leaks on existing radiators / pipe works. PS I am not a professional plumber but I have pinned a comment from someone that is. Good luck 🤞
@@MimiS6000 you should contact the plumber. If everything is brand new it’s most likely a loose connection on one of the radiators. Best to call your plumber to do a proper check
Hi, did this work? We have the same issue pressure going to 0.0 twice a day. We have a magnaclean attached and we’re thinking of adding the sealer to it. Thanks.

Why didn’t your installer fix the problem..!! And did he explain that when switching from open to closed circuit a pressure drop may happen due to old pipe joints or dodgy rad valves...!!!

@@georgeparkin4420 PS- I’ve pinned your comment.
Put a small sponge into the magnaclean to empty it. Also you need to do it twice to empty the bottle of Sentinel.
Did it work? I have the same issue on a brand new central heating system

I have brand new system did you find the cause of your problem?

Did it work? Haha
Everyone is asking DID IT WORK - no answer, so, I conclude the whole system blew up and reduced the house to rubble.
