    Hello all
    I am in the process of putting a concealed cistern and back to wall pan in my cloakroom. Due to lack of space things are tight and I have offset the cistern behind the pan by about 30mm to allow for the fitting of shelves either side. The pan is offset to the waste also but I can overcome this with a flexi waste connector.
    I was given the cistern by a kindly plumber on site so it did not come with all the fittings. I have used this siphon and this flushcone

    with the 90deg waste/feed pipe that came with the cistern which is 36mm.
    I need to put bend in the pipe to ensure a good seal on the pan, the angle at the mo is to acute for a good seal.
    I also need a compession nut for the entry into the siphon. The siphon did not come with this.
    In my ingnorance I purchased

    not knowing the pipe was 36mm, obviously it does not fit

    What are my options? Are there 36mm compression fittings availible like the offset above, I thought to swap out the pipe for 32mm or 40mm but that wont work with the flushcone or siphon from what I can see.
    Where can I purchase a compression nut for the pipe to siphon?
    Any help would be appreciated. Thanks in advance.

    the flush valve will be a standard 1 1/2 thread so get a nut and tapered washer from a good merchants, the universal bend will work with the flush pipe as it will fit welded waste pipe which is about the same O.D , if the flush pipe is a fraction bigger than the uni fitting you have then put one side of the uni in boiling water for a few mins which will soften it slightly and then with a chamfer on the flush pipe push it in, put the nut and washer on to the flush pipe first ;)
