How do you replace the washer/o ring within?

This drain off valve had started leaking for me and I can't figure out how I can remove the perishable sealing mechanism within. My first drain since installing it in November and I already have problems.
Asked by: AGLR
There may be debris stuck on the seal , it would need to be drained down flushed through or replaced.

Can this be added to an existing 15mm TRV

Can i fit this in between the copper piping and an existing 15mm Thermostatic Radiator Valve? Will this fit a 15mm Drain?
Asked by: PeteGore
No this will not fit between the copper pipe and valve.

Replacing old radiators

I am replacing pressed steel radiators with a width of 1035mm (1.35m). Can I replace with a 1000mm and will this make up the difference?
Asked by: Tryeverything
Yes the drain off tail piece will make up the 35mm you need.
