In my bathroom on the sink, I have had a leak for a while. After checking
it out I believe that it is because the tap unit is not waterproofed to the
sink unit. The tap has just been attached to the sink and i cant find any
trace of any kind of waterproofing so what is happening is that when water
goes on to the top part of the sink by the tap (Kids, wonderful eh ;) ) the
water drips down by the tap, down the pipes and out on to the floor.
What is the best stuff to use to seal this and what is the best method?
Silicone sealant. It will stay flexible. Unscrew the tap, underneath the
sink, and lift it a little (you may be able to do this without
disconnecting it from the supply). Clean underneath the tap, in the gap.
Squeeze a bead of sealant around the inside edge of the gap. Tighten the
tap back down and wipe away the excess with a damp tissue.
As you only need a very little - you may find a small tube of silicone
sealant intended for sealing leaks on cars to be more cost-effective
than a big tube intended for household/bathrooms.
