Works but slow water flow
I used this between a shower and macerator. It works but I think because the water pressure is low the flow is very slow. I reduced the shower pressure to avoid an overflow of the shower base

Does the job
This was a good money saver for me. Same product different branding was £30 in Screwfix and Toolstation.Put in horizontally. Make sure you see the arrows for flow and correct way up when putting in horizontally.

Either faulty or useless
Simply put it doesn't work. Fitted it under the bath and made sure the flow direction was correct and correctly aligned, tested some water down and nothing, the water didn't drain. Took everything apart, tested it again over the sink and the water doesn't flow through the valve. Emptied the water and blew through the pipe to open the valve and tested again, this time the valve opened and let the water to drain through. Fitted it back under the bath and guess what, the water is not draining again. So either the valve membrane is faulty or it just doesn't work as described. I thought the issue was because it was horizontal but even when upright (for like when fitted under a sink) during testing the water didn't drain. Don't waste your time with this.

Solved the smell problem.
My shower waste is connected to the large toilet waste pipe. Smells from toilet waste was travelling and you could smell in the shower. I fitted this and it completely solved the smell problem. There is very small amount of water slow down. Hardly noticeable.

Keep the smells out!
This is the second one of these I have fitted and they do a great job of letting water flow out but stopping smells coming in. One is on the outlet of an infrequently used shower whose waste trap is right over a central heating pipe, so in a week the water evaporates away. It's not that we are unwashed - we just prefer baths!The other is to fix smells arising out of a dodgy pipe layout that would be disruptive to re-route - again it has fixed the problem.Update after 6 months - works fine on normal flows from a hand basin, but can't cope with the flow from a power shower and causes shower tray to slowly fill up.
