The subject of bath, basin, shower or appliance waste pipes may not be a hot one but if you are planning on a kitchen or bathroom renovation or on moving an appliance such as a washing machine, it’s important to know your options when it comes to what waste pipe system you should or shouldn’t use.
Very similar to their larger cousins, the soil pipe, push fit waste pipes work in a similar manner in that the various couplings, joiners etc feature a rubber collar and when a pipe is push in, the seal compresses around the pipe forming a water tight seal.
These fittings are a little similar to the push fit type in that they rely on a rubber seal to make them water tight, but where push fit simply push together, these work in the same manner as copper compression fittings.
A compression cap is screwed down on to a rubber seal that forces it down in to the fitting or joint and creates a water tight seal around the pipe.
