These are great, if you get smelly waste pipe's etc. Clean the waste system pipes, etc. with a strong drain cleaner gel, fit this so all your waste, machine machine and dish washer outleets, all run through the non return valve. stops the drains stinking and a must have for your new appliances. It will not cure an old smelly washing machine or dishwasher, but will help along with your normal cleaning routine to keep your new appliances working as they should much, much longer. It certainly cured my waste pipe smell, instantly. They use these in commercial kitchens. Which tells you something.

Does what it is supposed to do stops water back flowing in my case washing machine back up into sink and smell from stack.Doddle to fit and clear out.helps in clearing out all waste pipe as washing machine will pump all debris out to the stack pipe and not back into sink.Will only work in a level pipe and wont stop back flow on trap mounted w machines(close to plug or u bend) I have a 2 meter pipe run and w machine is 1 meter from stack outlet.easy to fit as push fit type fittings just cut waste pipe to size and tighten fittings 10 min work if that and that includes getting access to pipe move w machine out.

Easy to fit and has resolved a long term problem with back-flow from the bath outlet to the shower, also fitted an AAV after the bath outlet to allow venting and quicker drainage.

I use this in my pool room on the shower as the waste line connects to pool filter back wash pipework. So when I back wash the filter the water does not come up into shower tray (15 psi approx) and when showering water drains away easilly. Saved the day for me
