Most reliable underfloor waste connectors?

[malx42]

I am in the process of building a shower in a loft room. The Shower Waste water pipes have to pass beneath the shower tray and will be totally inaccessible once the shower is complete. Which connectors are likely to be the most reliable long term, compression or push fit? I have had solvent jointed, boiler condensate pipe fail, (professionally installed) so I am not wanting to use this method of connection.

I would definitely use solvent weld.

Solvent weld

The reason why it’s failed on the boiler is the condense eats the glue over a period

Solvent weld every time and twice on a Friday.

+1 for the solvent weld. Do everything by the book and you'll be fine. Follow the instructions on the cement you use to the letter. Remember to debur the pipe after cutting it square.

Solvent weld.
Done properly, won’t pull apart, or sag.

Thanks for that. Good to know.
