Thanks for all the info Muggles and SL - this plumbing firm are specialist ufh installers and have said they will come and attach the required elbow reducers for us. They only ever work in 16mm pipe. They will also make sure all the tails are crimped to 15mm, thank goodness. As you rightly point...
Thanks JC - seems weird to have to reduce everything. My big problem then is that I was relying on a pushfit elbow to bring pipes from behind my tiled wall in the shower as I don't fancy compression where I can never get to it. Really need a reducing pushfit elbow.
Have an offcut of this 16mm...
They did all of the plumbing and are fitting an air source heat pump. All of the pipes are under the screed including hot and cold supply. They are commissioning the heating system but have left us the tails to connect up to appliances at some future date as and when we can afford to fit out...
No it's definitely 16mm - it has a metal layer sandwiched between plastic. Cut a piece off and although it takes an insert it doesn't fit in Hep2o or flowplast pushfit. It also doesn't fit in 15mm inlets for shower and presumably any other 15mm compression fittings. Looks vey slightly bigger in...
Hi experts
Plumbers have installed underfloor heating and left plastic tails for connecting up shower, basin, toilet etc. This all seems to be 16mm so does this mean adapters to fit all the 15mm appliances?
Many thanks
