In the Summer months was very rarely, it was most in the winter months (this suggested it was a leak in the central heating) and initially it was a top-up once a week, which then progressed to every 3 days.
Thanks. My tenants are topping it up every day at the moment. Started a month ago. I’m not sure if the sealant liquid is worth trying in this case or if the leak is too big.
@@HandymanSavage great thanks for reply. I ran it hard for 4 hours just on the rad where the solder ring was leaking and it’s definitely helped. Would have been a real pain to fix properly without making a total mess. Was losing 0.1 bar every few days it’s now been 7 days and no loss of pressure so far.
Also, if you’re doing it via the Omega filter like that one, screw the magnet out the top first before you drain it, to release all the sludge, otherwise the inhibitor will be stuck amongst it all. Good informative video though!
Thanks, appreciate the feedback, I usually get the magnetic filter cleared out when i get the annual boiler service, but i'll remember to do that before applying the Fennox next time.
I've had the boiler and expansion vessel checked a couple of times, all plumbers said it was a leak in the radiator piping somewhere, but so far this solution has plugged the leak wherever it is. Do you know of any methods to pinpoint where in the system the leak could be? I've had leaks where a patch on a ceiling has revealed the location, but this current leak did not show any obvious location.
did it work? how long does it last until you need to do it again?
Touch wood, still going strong no leaks, although just as a precaution I added some more during an annual service.
How often were you having to top up the boiler pressure?

can leak sealer obstruct pipes reducing flow
Not according to this - fernox.com/product/leak-sealer-f4-500ml/#:~:text=Effective%20within%201%2D24%20hours,as%20pumps%20and%20safety%20devices.
How long do you leave it in the system for?
It remains in the system by circulating around plugging any small leaks and then just mixes with the water, no harm done leaving in it.

If it’s every 3-4 weeks you’re just looking at a flat expansion vessel or passing PRV on the boiler not a leak mate
