Mixing Chems

[Grot]

Can I throw in

And

So that it protects & quits loosing pressure ....... All in one hit ?

Or do I have to do it separately........ Yeah I should go looking for the leak, but I really don't have the time.

Drained the system down in the summer to decorate ...... Rads Off etc etc & didn't replace the MB1 ........ now it requires its pressure topping up .... Every 4/6 weeks or so

Yes, no problems

i'd sort the leak first.

 

[Grot]

Will it bung up the leak & then put up with having a bit drained out in order to add the MB1 tho ?

 

[seco services]

should do.
have you checked all the joints that you done when decorating

 

[Grot]

yeah, its nowhere obvious
