Hi,
My house has suspended floors, so all the heating pipework has been done subfloor downstairs, with rising pipework to each radiator.
At the back of the house a drain valve has been installed which has been put through an outdoor airbrick. See picture.
Obviously the fact it's outside means it's a freeze risk. Also it's been poked through an airbrick where I want to put an external step.
Do I need to keep this? Or would I need to keep a drain valve at the lowest point of the heating system? With subfloor pipework, not sure where else I would be able to access it.
Any thoughts appreciated.
