Just been reading up on waste water pipe regs, as about to install a new bathroom and it got me thinking.
At my girlfriends parents house the condensate pipe from their boiler exits the house in 21.5mm pipe and then runs down the side in 32mm black waste pipe into the soil stack. However there is no trap? Is there a trap in the boiler to stop foul smells entering the house?
If a trap is required on the 32mm pipe can anyone recommend one that is fairly pleasing to the eye as it will be on the outside wall in view.
