Two possibilities. One, a screw is hidden under the red/blue mark which can be prised out. Two, the levers can be removed by being unscrewed. This will reveal a tiny allen screw. Oh, and these taps do not use washers. They are ceramic discs and only available after some research. Check they are not ...

Looks like a modern standard float valve washer to me. Any plumbers merchant or DIY will sell one. Check screwfix item 9115J.

Q1 sort of misses the point really. Yes, the flow will be poor because of the reduction in pipe size, but most importantly, a gravity fed shower MUST have dedicated hot and cold supplies; those feeds should be 22mm their entire length and finally the header tank in the loft must be high enough to gi...

You've really answered your own question about the smaller bore and bath flow rate; it's 40% less, and caused by the change in pipework. More to the point, any plumber worth their salt would be well aware of what a full bore serice valve is and where it should be used. They would also be aware that ...

One possibility is a mixer tap problem. If the outlet is restricted, when anyone turns both hot and cold on together, instead of coming out of the outlet, cold water which is of course at high pressure is forced back up the hot pipe in to the header tank. Some years ago, I fitted a mixer tap that tu...

There is a possibility that there is a blockage in the pipe underground somewhere. Air escaping back up a drain or toilet is a classic symptom. It needs to be investigated as a priority especially considering the amount of rain we are having recently. It is conceivable the toilet may start to back u...

No. You must keep the stack if it is the only one for the property. Removing it may cause problems with the flow of water through the pipes. It may result in airlocks which block flow and odours which may escape inside the house.

Water hammer can happen at any time. In extreme circumstances, it is even possible for a neighbour to cause the noise. Water hammer is typically a single bump or bang and you wouldn't expect it to last 5 or 10 seconds as you describe. Unfortunately, as you have given such scant information, a diagno...

And there seem to be plenty of options for wireless thermostats for modern full-pumped system and combi boilers. There is no difference between a thermostat used to control a gravity system and one to control a combi boiler. What might be different is that most installations nowadays use a programm...

Unfortunately, Scottish Power have an appalling reputation for ......well, I was going to say customer service, but in reality it is any type of contact actually. OFGEM I believe fined them heavily recently and stopped them for taking on new customers until they had caught up with the backlog of cus...

There is no need to replace a cast iron stack if it appears to be in sound condition. Just check if it is firmly fixed to the wall, and that all joints are sound and there are no obvious cracks in the pipe itself. I have known the swan neck part which often is fitted at the top to step out past a gu...

The noise is most likely caused by an ageing rubber washer in the float valve. As the washer ages, it becomes hard and brittle making it unable to absorb vibration caused when the water flows in to the cistern.

Replacing the 50p washer will cure the noise.

Unfortunately, the advice you have been given is most likely correct. There are hundreds, probably thousands of different designs of cubicle out there, and designs come and go just as distributors do. To expect anyone to identify a spare part simply from the part itself is impossible. If you could i...

Certainly, as long as the stack remains vented, and the vent is above the height of the basin then that will be satisfactory. What you suggest will be fine.
