    Hi,

    I had posted this query on the Building Regs Forum but did not have much of a response. I wonder if any of the plumbers out there could help me please?

    I am planning the creation and installation of two new bathrooms on a 1st and 2nd floor. The WCs will be sited at the far corner of the property from the existing soil stack.

    I am aware that Building Control will be able to set me right but, I want to have all of my decisions made if possible, before getting them involved.

    My questions are, what is the maximum number of bends permissible and, what are the maximum pipe lengths allowed, if vented?

    I attach a sketch to show the planned arrangement and dimensions.

    Many thanks in advance, for any help.

    As it is vented you can have as many bends as you like and the pipe can be as long as you need. As long as it is all to the correct fall.

    Hi denso13,

    That is good news and looks a lot more promising. Thanks for the reply.

    I've been worrying about this one all weekend.

    Regards.
