How to plug a drainpipe hole in particle board?

[rocker]

During a recent renovation the plumber had to penetrate a particle board cupboard at the corner, as per the photo.

Clearly there was no corner flange to cover the entry hole, unlike the exit hole which does have one.

Does anyone have a solution to filling that hole?

Thanks.

Hi @rocker,

You could potentially use expanding foam to fill these gaps. I'd suggest using Parfix 750g Expanding Foam Filler and then trimming the excess, so it's flush with the cabinet wall. Alternatively, you could cut down a Kinetic 50mm Waste Tray Floor Flange to fill around the majority of the pipe and then add a small section of time to neaten up the right-hand side. I've created the below rendering to illustrate.

Please let me know if you have any questions.

Morning @rocker 

I think @MitchellMc has come up with a really impressive solution.

Mine is less so.

I was thinking thin white plastic (Newsagent or Office Works) cut appropriately, with some origami and glued into position.

At least I tried.

@MitchellMc That drawing is truly impressive! Cutting the 50 mm floor flange would help with installing as pipes are already glued.

The only tricky bit would be to get the angle of the hole right on the right hand wall. 

In which aisle will I find the "small section of time"? 😉

Hi @MitchellMc 

Just a random thought while chewing on lunch - but @rocker will need to remove that elbow joint to fit that "C" section? PVC diameter is - ?

Amazing hole. The plumber used a hole saw - from the opposite side?

[rocker]

@Noyade If @MitchellMc hadn't trumped you with his software, I reckon your effort will have sufficed. 

That said, my origami will be sorely tested. Thanks for your input.

[rocker]

Yep, actually the hole was drilled by the builder who did the bathroom reno on the other side of the kitchen wall. He is a real tradesman (but again, did not take my request to plug holes seriously enough). 

No worries though, I'll have a go at your solution.

There was rapid posting there @rocker !

Thanks - 50mm.

Good luck with either method, or whatever you do - I would like to see the finished 'patch.' 😁

[MitchellMc]

@Noyade,

I'm hoping the flange plastic is flexible enough that you can make a bit of a twisty motion and squeeze the C opening over the pipe.

Yeah, lunch break! 

If the patch is neat, I'd be happy to add it, if messy, I think I'll just let it go quietly!
