Brown water and Banging from pipes

[craig297060]

Hello

For some time now i have had Brown silty water coming from the hot water taps whilst the boiler is on.In addition the boiler or pipes makes a loud Banging sound.Also when the radiators / heating is turned off but hot water on the upstairs rads still heat up?? when the boiler is switched off completely and the hot water run the brown water eventually clears.

I have checked the expansion tank and there is brown sediment sitting on the bottom, i tried draining the system refilling and bled the rads but nothing has changed.

Does anyone have any ideas??
thanks, craig

needs cleaning, possibly new cylinder, motorised valve(s), re-piping

How many tanks in the loft 1 or 2.

What height is the water in relation to each tank, is one higher than the other, and if so which.

 

[craig297060]

only one tank in the the loft, water height is is about an inch and half from the top of the tank just below the ball valve , thick brown sediment sitting at the bottom of the tank!!

Can you see the word Primatic on the top side of the cylinder, just above the heating pipes.

You need to turn the water off and drain the cylinder, and slowly re-fill.

The boiler needs to be off

And don't add any chemicals!

When you say no difference, it will take a day for it to settle down, unless you run bucket loads of water off.

The banging could be related to loosing the air bubble.

Check the pump is working.

Never heard of marsmatic, and neither has google it would seem.
