    I am in the process of building a shower in a loft room. The Shower Waste water pipes have to pass beneath the shower tray and will be totally inaccessible once the shower is complete. Which connectors are likely to be the most reliable long term, compression or push fit? I have had solvent...

    PVC bath pipe work and waste

    Hi All, I’m in the process of fitting a bath and have just finished solvent welding the 40mm waste pipe up to the bath. Now I’ve put the bath in situ, the pipe work is slightly out, about half an inch. I can pull it into place but this will put a bit of tension/stress in the pipe and on the...

    Shower waste pipe

    Hi all, I'm due to do a first fix for an ensuite. WC is going back in the same position. The basin can use the vertical 32mm pipe. But what are my chances of replacing that cut-off section of shower pipe? Just wondering how you'd all approach it? Thanks everyone for your advice, Jennie

    Waste pipe on unvented blow offs??

    Hi all. I’m not G3 qualified but I’m sure I heard that the waste pipe should be push fit plastic rather than solvent due to temperature? Is this correct? Most cylinder installs I see the discharge is in solvent. Cheers

    Hi I want to replace the 32 & 40mm waste pipes that connect to my external soil stack, not enough fall so not draining.

    40mm waste to 110 horizontal soil

    Hi. Just about to put joists in new part of the house but got the basin and shower waste exactly where I need to go.

    toilet pan waste pipe

    I hear flexible waste pipe is better than non flexible one as the flexible one sits tightly into the soil pipe. Does one know whether one should apply glue onto the flexible waste pipe when inserting it into the soil pipe?

    Evening everybody I've seen a few threads on this topic but was hoping for some specific advice if possible. We've recently moved in to a 1930s semi that was a half completed project for the previous owner. The downstairs cloakroom is our first job - we were hoping to box a new toilet cistern...

    Waste pipe size query

    Hi, I have a basin trap that has a 35mm chrome waste pipe supplied. I was wondering if this can converted to standard 32mm pipe as the chrome isn't long enough. I seems odd that the Chrome pipe isn't a standard size? Thanks

    Currently the Dishwasher has it's own waste outlet to the outside, the sink and Washing Machine share one. Designing a new kitchen we will have all of them sharing one waste outlet - is this do-able or full of problems?
