    I'm at the final stages of working our my bathroom plumbing and I'm confused about the toilet waste.

    I need to have the pan connector come out horizontally to connect to the soil pipe on the wall, is this ok?

    I hope my diagram below makes sens. The right angle pan connectors are only 240mm long, so I think i need an extender to reach the soil pipe. The soil pipe is further from the back wall than the hole on the toilet so I need to adjust for this somehow. It's also 50mm lower but that's good for the drop, if these connections have enough give?

    These are the various mcalpine parts that could work, but I'm unsure of how they differ or how they fit together. Any advice on what might work based on my diagram would be extremely helpful.

    These are the various 90 degree pan connectors :

    Macfit pan connector

    Rigid pan connector

    Space saving pan connector

    And the extension pieces :

    macfit extension

    Straight extension

    Offset extension

    You want to use 110mm soil pipe up as close to the pan as possible so you only need to use 1 pan connector. It may be more straightforward for you to use a 110mm 90deg elbow to go left from the wall, a short piece of pipe, then another 90Deg to go left towards the toilet and then a small piece of pipe and/or a long right angled rigid pan connector to fit to that.

    50mm drop over 600mm would be loads.

    I should have drawn it, but there's a window there, it would feel very cramped

    But the pipe is pipe is only 13mm from the wall and it's a short run to get to the toilet, so I don't see why make lots of corners? It's hidden in the corner and I could box it in after.

    You said not to use more than one pan connector, do you also mean the extension prices I linked to? If not using an extension how do you join two pieces of 110mm pipe, can you do solvent weld

    Sorry im I'm a bit confused,o aretare youa making trying to deal with difference in distance from the wall between the soil pipe and the toilet waste outlet?

    Also, can you just solvent weld 110mm waste pipe like smaller water pipes? If so, why do they make those extenders I linked to

    110mm plastic should be uPVC, and will happily solvent weld, (most plastic pipe manufacturers also make a range of solvent weld soil.) If you are in a position to extend the existing soil pipe with rigid pipe and fittings, then that is a far superior option.

    The extension pieces in your links are for situations where other materials are present, cutting and extending a cast iron soil pipe for example, isn't a job for the faint hearted!

    If it is 130mm to the centre of the existing pipe as per your sketch then just come straight off it with no bends and fit a bent pan connector at the toilet.

    Is the existing pipe a plain end or socket? how far does it stick out from the wall?

    Thanks, what's a bent pan connector? If I used the space saving pan connector that I linked to, then it comes off horizontally exactly at the same place as the toilet waste outlet. So then there's a 30mm discrepancy between the toilet and the wall, over a distance of 500mm will this be able to just got at a slight angle? Do you think this space saving one used horizontally will cause any issues with that bend in it?

    The existing pipe is a plain end and sticks out about 25mm now, but after render and plaster I doubt there will be much left. But I won't plaster right up to it so there will always be that 25mm to attach something to. Should I use solvent weld here, or some sort of attachment? Might be useful if it can come off if there are toilet issues

    Thanks for all the help, so useful!

    I would get a coupling onto that end before you plaster, in this instance a solvent weld version may be better as they are slimmer and will require less of the surrounding wall chopping away to accommodate. (Check before applying any glue, some are 'handed' with an arrow in direction of flow!)

    See how it line up with the pan, Space Saver connector may well fit without too much ado.

    Ok thanks, so basically solvent weld whit 110mm pipes from the wall to the toilet and just use a 90 degree pan connector at the end

    Yup, +1 .....

    Just remember to line it up /fit it all together before you mark/glue to ensure it's all correct and the fall lines up when the toilet's finally in. Also remember to factor in the height of the floor covering too.
