Sealing a wavin WAJ lid

antoinolachtnai

I have a wavin 110mm WAJ lid in what is basically a closet in the bathroom. Nowhere else it could go really. It's a basement and the pipes are pretty near the floor level.

Now things are basically going well. No backing up, no silting, no major problems. However, there is a slight smell from the WAJ lid (which is about 325mm square).

When I bought it, I asked the well known building supplier/ plumbers merchant about it and was told to grease it and screw it down, it would be fine.

I've greased it now, pretty well, but haven't screwed it down as yet. There is much less of a smell but still a bit.

Taking another angle, the wavin cqtalogue sort of suggests there is a sealed lid available for this but the person on the wavin sales line today tells me there isn't.

What next?

Will a bit more grease and some screws do?

Would a seal using neoprene strips help?

If it really came to it I could put a larger double seal lid on top but it would be messy. Floor level would be a mess and I might end up damaging the waterproof seal between the AJ and frame. That sounds like a bad idea seeing how everything is low enough as it is.

Your asking for advice on something thats not been done as its against building regs.

If it were me i would have used a silicone seal for the same reason you use greese.

its easy to remove should you need to.

Another solution might be to introduce a vent just out side the house running up the wall with a cap on it that way the smell can escape.
however you risk a back draft blowing against the lid but doubt it.

Yes I realize now I am in the murky world of non-standard.

Is there any simple way to properly seal this, I.e. to standard? Is there any better way than putting a new frame and lid above what is already there?

Is any particular type of silicone better than others for this job?

Thanks for the tip.

You cannot use silicone now that you have used greese. Stick with the greese imo.

Thanks again, followed your advice and also used some neoprene sponge seal I had for pig iron.

Now, is it ok to use ordinary wood screws? Or is there something more specific?

Thanks for the help.

No. not really. but then i would not actually screw into the lid itself.

I would buy brass screws and a pce of flat steel and screw the steel to the floor. That way the screws are not breaking the shore seal
