FloPlast Washing machine Trap (Dia)40mm

I was a bit apprehensive buying this after seeing a few bad reviews on here and Tool Station. Admittedly, Floplast are normally pretty good but this Hockey Stick is far from it.
Several people have the same problem as me when fitting this.
On the U bend there is one fitting where the rubber washer is about 2mm thick, so you'd need to tighten it very well in order to create a good seel. Even before getting it remotely tight, the fitting skip a thread, thus not allowing you to tighten against the rubber washer.

Please don't waste your time and money buying this.

One end is 40mm the other is 38mm
But It doesn’t tell you on the packet
You only find out when you get home

Bought this full kit, fairly easy to install, the rubber seals on the mating nuts needed to be tweaked to get a seal and the flange also made a good seal.
I had to cut down the pipe to fit in the flange.

I bought this, to replace the poor installation job that was under my kitchen sink, as this has now helped (along with other parts I bought) to get me washing machine waste pipe and u-bend seperate from the sinks u-bend, and in turn has stopped the former sinks u-bend with washing machine nibble for hose connecting, contaminating My washing Machine, ,

this though I admit, I did trim the length of the 600mm down pipe down slightly, but with the other 40mm take away pipe at slop of 20o this has help and with geting TEE JOINT 40mm too, and a new under sink u-bend, I have got bought my sink and washing machine working fine, and infact they are both dring away lot better,
