Hi I have an old central heating system (I guess at least 20 years). The selection of Hot Water (only), Central Heating (only) or Hot Water plus Central heating is manually controlled by (hand) via a circular shaped brass value
The valve 'control' is fronted by a blue plastic dial that rotates
360 degrees, and has the above selection written in white lettering upon it.The valve is/was made by Switchmaster. (I have a picture if anyones interested)
The valve may have developed an internal leak or broken it's seal - When Hot Water only is selected, some water is diverted to Central Heating - meaning the rads are warming up unnecessarily.
can anyone advise either where
- could I get a replacement for the Switchmaster
- Is there another form of 3 way valve I could use - it doesnt have to be elegant - as this is all locked away in a cupboard - I've done the usual google searches but had no luck so far
Kind regards Carl
