September 24, 20215 yr Builder's subbie plumber mentioned Hep2O 15mm And a bronze pump "secondary return" for quick hot water at kitchen sink, basins Until then I had assumed it would be PEX pipes Question: Is there much in it between Hep2O & PEX pipes? Initial cost is a consideration
September 24, 20215 yr PEX is relatively stiff and so I tend to prefer the flexibility of Hep2O (PB). I've not much experience of the former though so it might not be bad in practice.
