    Any future problems ? Who knows but speedfit is acceptable in inaccessible areas. As long as it’s been pushed in and tightened properly it should be fine for 20+ years

    Looking at the pic again if you wanted you could demount the fittings and solder elbows. Joining back into the plastic with fittings that aren’t going to be sited under the tray. Up to you though

    Bit of hair felt lagging where heating pipes touch wood or they may creek
    Insulate between cold water and heating pipes or the cold will be warmed

    The only thing I would say is to cut off the waste as is and put your elbow etc on so there is far less under floor...
    Why?
    Cos if that much goes under floor it is extremely unlikely to have a decent fall on it. That WILL become a problem at some point. By lifting it as high as you can you will minimise the chances of those problem arising. Further, even if its slightly blocked now, the water running away properly will begin to clear existing small blockages.

    I'm afraid I would redo the connections to the plastic so that there was NO stress from the bent pipework on the connection. SF are frankly not good at coping long term with that. It's very clear in the MIs that it should not be done. It specifies just a 5 degree max offset like that and specifically NO stress.

    I'm with Shaun on the testing bit too. DO NOT forget to pressure test the waste too. Been there done it and paid the price :eek:

    Good job. Good luck.
