    Loosening plastic plumbing screw ring thing

    Loosening plastic plumbing screw ring thing 19th Feb 12 at 1:24 PM
    I need to clean the u-bend underneath my bath plug, as the bath water runs out too slowly.

    The plastic u-bend pipe is fixed to the main down pipe with a round plastic ring...and I can't budge it at all!!!

    Are there any tips anyone can kindly offer up??

    Have tried to use my biggest pair of claw grips, but the are still to small to fit around the ring (which is approx 2 inch diameter-ish.

    thanks all

    Try from the following
    Water pump pliers www.screwfix.com part no 25268
    Pipe wrench www.screwfix.com part number 57920
    Boa constrictor rubber wrench www.bes.co.uk part no 7746

    I would probably try the last one first in view of limited space. I have given the refs so that you can see what they look like. the diy sheds also sell them. You need to be careful not to crush the plastic pipe.

    Good luck
    Roger

    I've used one of the chain type car oil filter wrenches successfully if you've got room to get it in.

    Try loosening thesecond ring nut (P trap outlet) then rotate the whole P trap slightly to assist with loosening the first ring nut.

    Thanks so much for all the tips.
    Moss..yes, i have tried this idea too...got the other ring loosened, and then tried the culprit ring..but still to no avail.
    I may have to resort to using chemicals to pour down and unblock..I think it's long hairs that have accumulated..
    Thanks again, everyone.

    Hot sodium hydroxide (causic soda) will dissolve the hair/soap scum. Pretty plastic friendly too and doesnt cost a lot!

    Only mix it with warm water as when it dissolves it becomes extremely hot. Wouldnt spill it on an enamel bath either.

    sometimes they stick so badly the only option is to cut them off and replace the whole part.
    i did one recently. it was stuck together using evostik! (on the threads).
    due to space restrictions, i had to chisel it off.


    luckily the parts required are pretty cheap.
    Get some gorm.

    If it is truly a round plastic ring on the soil stack as you say it might not be a fitting that unscrews, but a push fit connector with an "O" ring

    He's not talking about the soil stack but you might be correct about it being push fit.

    OP can you post a pic?

    You could try to get a big screwdriver and use it as a chisel, gently tap the little plastic bits that stick out all around the ring.
    Now that i'm what you could describe as an older person i've stopped eating health foods.
    I need all the preservatives i can get.
