has anyone attempted a "diy" to replace the flow meters and valve pins on a warmafloor UFH manifold ? also how easy is it to just replace the whole thing as I'm seeing manifolds for under £200 and wondering if its worth buying parts or just replace the whole thing but I'm not sure how straight forward is this also those grey pipes are they compression fitting ?
a plumber quoted me £1400 just to replace it
and another wanted £1200, they didn't mention VAT so assuming thats ex VAT
