Adding sealant to system

[cagdas alcicek]

Hello,

I have recently installed a new boiler and my pressure is still dropping every few days. I've been told that its due to a leak somewhere in the pipework. I cant see any leaks on the radiators or valves, and the pipes are under concrete underground. I was going to add some Sentinel Leak sealer (this one to be exact) to see if it would fix the issue before taking any drastic measures.

I have a magnaclean filter installed. My question is, are these sealants harmful to this filter in any way?

Thanks,
Cagdas

No mate it is fine to use on your MagnClean.

Awesome, thanks Darren.

If I were you I would call the previous installer back and let them do it. They should give you some sort of warranty on their installation. Good luck mate

I think i read or heard somewhere that leak sealer is just pva

I would make absolutely sure the leak is on the system and not the boiler before putting that stuff in it , I have never used it and never will , the lads I know who have used it have very mixed opinions on it . What boiler is it ? , did it leak before ?

Ive never liked leak sealer as was always under the belief that they werent good for the system although newer ones are not so bad ,,, now i dont know the facts on sealer so im just saying wots in my head but if i was going to use it and put it into the big magnet id check wots in the ingredients incase it sticks to the magnet lol

I was always under the impression that some manufacturers don't like it in there boilers and it voids the warranty, but I may be mistaken.

Out of curiosity, can this stuff seal up AAV's ?
like the one inside your boiler ?
Just asking because I don't use it so I don't know much about it

They say it's not supposed to but we all know it could
