Rated 5 out of 5 by from It worked ! Like many others I was sceptical, one plumber told me I had a leak in the boiler expansion tank, another a leak somewhere else in a pipe. boiler throwing low pressure alarm each 3 weeks. 3 pourings into the magnaclean and 10 weeks later no issues. really easy and cheap fix.

Rated 3 out of 5 by from bigger leak than a weep Had this as better value than similar product sold by competitor. Bigger leak than first thought. Had to try this as don't know where leak is, no puddles or sign of water. All pipework in concrete floor of bungalow and 80% tiled. Going to replace with new pipework going through attic

Hi would this help with a leaking shower trap, if I poured down the trap?

Is Sentinel Leak Sealer suitable for "O" ring leakage?

Asked by: Ian1548
Hello- If there is a problem with the O ring in your filter, you will need to look to see if it is damaged and needs to be replaced. The Sentinel Leak Sealer is ideal for sealing weeping joints or pinhole leaks. Kind Regards, Sentinel Customer Services
