I have lately unblocked my basin sink surrounded by my bathroom using a liquid drain cleaner later a sink plunger.
The sink was unblocked succesfully, but for some basis i have a small drip coming out a the hole from the bottom underneath the not here hand side of the sink mixing bowl.
I have be told that the only use of this hole be to hang the sink up after it be made.
Any ideas please?
Answers:    Hi Anthony,

Sounds resembling you have dog-eared the seals using the drain cleaner, sometimes the idle away water can find its course into the cavitities in the sink, depending on the size of the leach, I would leave it for a couple of weeks and use the sink as majority and hope the leak will reseal itself, as taking out the consume, esp. on older sinks is no fun at adjectives and can make matter worse.

Good Luck
