overflow pipe

[carver]

Hi,
following my condenser pipe freezing I am routing it internally to join a bath waste.
Does the 21.5mm pipe need to be solvent welded or is it just push fit. I have had differing opinions at suppliers.
Thanks

Don't know if this will affect you or not, but our plumber recommended us not to route it to an internal drain as it will corode the pipes (unless they are plastic of course). Not sure if this is true but just thought i'd mention it

Hopefully someone will back-up or dismiss this anomaly

You can connect the condense to the bath waste with a inline/self sealing trap. I don't see why you can't use glue. We use it all the time.

The condensate is acidic, so will rot a metal pipe. If you are connecting to plastic waste then there wont be a problem.

I would use solvent weld pipe, its going to handle a fair drop of water, so would be better sealed.

Thanks for your help.
Yes it is going into plastic pipe, but what exactly do you mean by an inline/selfsealing trap?
Thanks

If your boiler does not have an internal trap on the condense then you will need to incorporate one. A self sealing or inline trap or HepVo trap looks like this:

Whatever you please but solvent preffered. You won't need the hepV0 if your boiler is fairly new. Just make sure the condensate pipe is dropping into the waste.
