Help! - Leaking basin trap (Pictures)

[outmyway]

This basin trap is driving me mad ... I've taken it apart and reset it so many times but it keeps leaking ....

See pics below to see where its leaking ...

Should I use silicon on the trap-waste seal and on the underside of the basin waste seal+thread?

I dont understand how water is getting into the waste thread and running down?

You got a rubber washer under that brass nut?

You got a rubber washer under that brass nut?

libby - Yeah ... plus I have tried two wastes with two different types of washers.

Its a slotted waste .... I guess the water is building up under that nut/washer and slowly running down the thread?

I normally silicon the space between the waste threads and the basin,(careful not to block the overflow) plus a bit of ptfe on the threads where the nut sits usually stops any leaks.

As Picasso, ignore most traps and washers, silicone everything

You need to silicone seal before fitting washer/nut.

Why silicone? I never use silicone, only used plumber's putty and poly washer. Fitted hundred of basin and never had problem.

[outmyway]

Thanks for the quick replies ...

I have now siliconed above the nut and washer ....

.... PTFE tape on the flange of trap to waste join + the rubber washer in there ... if that doesn't work I will silicon in there too!!

I will wait until morning to let the silicon set ... watch this space!

Nah, I rather use plumbers mait. Old habit.
100% leak proof. You can test it straight away rather than wait for silicone to set.

Let me guess , you are atleast in your late 50's ?

 

[stardanny]

No, early 40's. Been taught by a old plumber.

Water coming from A will be to do with the seal between the basin and the waste flange or back nut. (Or both.)

Water coming from B will be to do with the sealing washer in the trap's nut.

Are we dealing with 2 issues here?

PS: We sell very little Plumbers Mait nowadays. Most of those who used it are either retired or dead.
