Grundfos 3 bar pump and Tectite fittings

paddy147 · 2011-12-16 22:13:16

Would a Tectite push fitting leak due to the pressure from hot water being pumped around to a hot water basin tap by a Grundos 3 bar pump?? The piping in 3/4 inch qualpex. Thanks.:)

normally they are okay as long as the insert is in.

However one issue with the push ons is that any scratches on the pipe-work where the rubber O ring surround the pipe in the fitting will leak under pressure.

v easy to scratch 'pex longitudinally when pulling along ground etc

In the odd case the fitting may be faulty.

[have u tried spray foam]
