Dosing both inhibiter and leak sealer

Bankrupt · 2 Mar 2011

My central heating is about due a new dose of inhibiter. I'm using Sentinel X100 rapid dose.

I'm also going to dose with Sentinel leak sealer (also rapid dose) as there must be a small leak somewhere - pressure falls faster than it should.

Can anyone advise me whether I should circulate one treatment before injecting the other, or is it OK to bung them both in at the same time ?

I suggest you add the leak sealer first and run system to see if it improves the situation. If all ok, then add the inhibitor, as you don't want to waste the inhibitor if you need to further investigate where the leak is coming from. Obviously you've checked all the rads and valves and especially any drain off points to the system.

Surprising how many add leak sealer without checking the PRV vent.

Better to fix the leaks!

Agreed, but I think my leak must be one of these pesky "invisible" leaks ! - It must be tiny, just means I have to top up the system 3 times per year instead of once per year or so....

Can't see any problem at the pressure release valve vent... I suspect it's a tiny leak on one compression fitting...

My concern was if there was a possibility of reaction between the concentrated inhibiter and leak sealer - I'll circulate the leak sealer first before I re-isolate the radiator and put in the inhibiter just to be on the safe side....

Ok if it only 3 times a year to top up, the leak is very small, and the leak sealer should stop it.
