I would like to add an ensuite to my main bedroom. The ensuite would have a basin, a WC and a shower. My problem is the drains and soil pipe is on the other side of the house and a concrete drive and a decked patio makes it difficult to add another drain.I have searched the internet but cant seem to find a solution, so please could any of you experienced people advise. Is there a saniflow system that could cope with the waste from the shower , sink , and WC and if so what model of saniflow and the best place to purchase it. Many thanks in anticipation of your advice.
