Is there any reason why the condensate pipe from the boiler can't be connected horizontally into the start of the 40mm waste pipe run which runs under the kitchen sink, using one of these: https://mcalpineplumbing.com/plastic-chrome-fittings/multifit-waste-fittings/r17-reducer-abs (providing the correct guidelines are followed regarding the rate of drop) or must it connect into the waste pipe from above using something like this: https://mcalpineplumbing.com/traps/condensate-traps-and-fittings/v1mx-co-universal-slip-tee ?
Thanks!
Thanks!
