B&Q Chrome effect Slotted Plug & chain Basin Waste

This product is completely usesless as sold simply because it is not "Fit for purpose"
It is IMPOSSIBLE to get a watertight seal on the underside of the basin ,no matter how tight you turn the locking nut!!
You will end up (as I did ) using mastic sealant or plumbers putty to make a watertight seal .This means that the thing is sealed permanently to the underside of the sink,messy and awkward should you need to change it ever again!!
Complete waste of time and money!!

I fitted this waste to a new wash basin, everything standard including the integral overflow in the basin. The instructions tell you to add sealant to the joint between the waste and the surface of the sink. Unfortunately this won’t seal it on its own !, it leakes like a sieve. The problem is the poor rubber washer that goes under the basin that the large nut tightens up to. Trying to tighten it up and up just makes things worse because the water is getting past the thread and washer via the overflow holes. After much muttering - I resorted to my trusty plumbers putty (‘plumbers mate’ - it’s like plasticine ) applied to the top joint between fitting and basin and then also between basin and the large washer under the basin. This created an instant seal once all squeezed up via the plastic nut. So if you read plenty of troublesome reviews, plumbers mate is what you need, it’s about £7 per pot and lasts years if you don’t let it freeze. If you call a plumber to do it, plumbers mate will be brought out if the van ! Plus an £80 bill no doubt.....

No problems fitting and sealed first time with no re-work required. Only problem was how to fix the chain to the basin - there is no securing lug or whatever.

Basic and Affordable. Could have done with a bigger length of chain though
