It was fit by a gas safe engineer, he fit everything and expected the builder to fit the condensate pipe to the waste pipe but he left before he fit it and just hid the issue behind my dishwasher.
I'm now trying to find out how to fit this condensate pipe to my waste pipe. Is it a DIY friendly job? If so, can anyone give me a guide? I am coming in very new to this so I have 0 idea of what I need to do.
