Rated 1 out of 5 by from Rubbish Purchased it to link in two washing machines. Water did not pass through and went back up pipe Zen’s kn to floor. Purchased McAlpine one and that did job.

Rated 5 out of 5 by from Sewage smell eliminated I bought this Viva Magna self sealing waste valve to stop the bad smell coming out of the shower waste which siphoned every time the sink was used. I had fitted a drain trap to the sink with a trap valve to try to overcome the problem but that was just a waste of money. I could have bought a much more expensive make of self sealing waste valve but decided to buy this one as it was much much cheaper and came with a compression adaptor and an elbow giving lots of options. Plus it was delivered free of charge the next day. I now have a completely smell free bathroom. Well done Viva Magna and Toolstation.

Rated 5 out of 5 by from Brilliant! Tried everything on the market to stop foul drain smalls coming back through my shallow bath and shower traps which passed as a result of evaporation of contents. Why oh why are these shallow traps so useless?!? Nothing worked until this little beauty came into my knowledge! Fitted one to each of my affected bathroom outlets and hey presto, smell has at last been defeated! Easy fit, but you do need a straight run of about 200mm of pipe to splice one in. Quality is excellent too, and compared to rivals, a total bargain.
