I'm about to embark on a bit of pipe replacement/rationalising/tidying up.
Cold supply, DHW, CH.
Some is in copper, some in Hep2O, the 'old' grey type.
At a couple of points I'll have to disconnect some Hep2O fittings and reuse them, like this:
Where the CH flow and return come through a wall, I'll have to disconnect a 90 deg elbow, rotate it through about 90 degrees and reconnect.
Similarly where the 15mm hot and cold come through a wall, I'll have to take a couple of 90 deg elbows off and replace them with Ts.
These fittings are very close to the wall.
Questions:
1. Is it OK just to loosen a Hep2O fitting and turn it?
2. Where I actually take a pipe out of a fitting the Hepworths manual talks about replacing the O ring, wedge and wedge support ring. This is old grey Hep2O. Do plumbers merchants still stock these?
Many thanks.
