Hello!
Bit of background: We live in a 3 storey block of flats on the top floor in a 1 bed, 1 bathroom flat (built around 1987). There is no gas supply and heating is via x3 storage heaters. We have a System boiler (?) with a tank in a cupboard next to the kitchen. The water pressure is quite bad and so we have a power shower.
Whenever you use the the power shower or flush the toilet there is a crazy banging noise from the pipes that lasts about 1-2 minutes - I think it's mostly coming from pipes close to the boiler.
While the pipes are banging, in most cases if you turn the kitchen sink tap off and on it stops the noise - seems weird but it generally works.
Can anyone tell me what the problem is and how it can be fixed. I'm praying that's it's not expensive, is it possible to give a rough estimate on price?
My understanding of plumbing is non existent - so if I do need to get a plumber is there anything in particular I should say or ask about?
A massive thank you to anyone that can help.
Thanks,
Ben
 
Has there been any water treatment works done nearby recently? Have you turned off your main screw down valve recently?
Sound to me like too much water pressure so you might need a pressure reducing valve installed. Could also be debris in the shower filter & toilet washer.

Meant water mains work not treatment sorry.
 
Hi all,
Here is a pic of the tank... I'm about 99% certain the noise only happens when the boiler is turned on... but not sure if that helps.
If you look to the side of the picture there are two switches which I use to turn on the boiler... not sure what they do individually. There's also a timer which I use when the boiler is on.
Above this is the other tank (cold water?).
I think the main screw is in a cupboard in the hallway... never really used this.
Thanks for all the help

Sorry mate, that's all there is in the flat... it's an electric system... what else am I looking for? Would it be outside the flat? In the loft (we're on the top floor) or hallway cupboard maybe?
 
Sound like water hammer usually caused by a faulty inlet valve (loose jumper/washer). A new washer for your float valve in your header tank, the inlet valve to the toilet or the incoming mains stopcock will probably do the trick. Also try turning the incoming mains stopcock down a few of turns clockwise and see if it rectify's or lessens the problem.
 
That's great Darren, thanks for your help.
Does anyone know a plumber in Horley (near Gatwick) that could fix this and how much it would be?
 
Not sure if this is the right place to ask previous questions but if anyone can point me in right direction that would be great.
Thanks
