Dear plumbbob - sorry to highjack this thread Garfield, but our hammer tap is driving us mad, especially as it's also present in the flat above and the guy uses his taps up to 3/4 in the morning!
We are basement and raised ground floors. Mains enter our flat at basement level in a stack behind the toilet cistern.
We've put the hammer tap arrestor in the cistern itself, but the hammer tap is still audible.
We haven't done any plumbing work, nor drained anything in the system since Summer 2012, but the hammer tap only started around April this year, from one day to the next.
Our neighbour upstairs claims he hasn't done any plumbing work or drained anything either.
Coincidentally (though I don't believe in coincidences!) our 2 sets of neighbours next door have also developed a hammer tap at exactly the same time.
We called Thames Water out to check the pressure. Ours is 4 bar in the street which is quite high, but not the highest ever seen.
Thames W claim they haven't raised the pressure in our area at all, but we have no way of knowing if that is true or not.
What elese could have created a hammer tap, in 4 separate maisonettes, at the same time, when nobody has done any plumbing, other than a central problem through Thames water?
Also, why has our arrestor not worked, you think?
Worth mentioning that all the plumbing in our bath is new since summer last year. yes, there are probably sections of dead pipe in a 4 storey Victorian terraced building, which we know nothing about, but they have always been there and the hammer tap only started a few months ago.
Please help :-)
