I am intrigued by all the negative comments about Hep20 fittings on the basis that they require a tool to remove the fitting. The main use of PB-1 is in flexible pressure piping systems for hot and cold drinking water distribution, pre-insulated district heating networks and surface heating and cooling systems.
Plastic pollution Great Pacific garbage patch Persistent organic pollutant Dioxins List of environmental health hazards. So with a 10m long 15mm pipe the wait will be 10 seconds, but with a 10mm pipe the wait will be 3 seconds, so very little difference.
