Hi,
I have just replaced the diaphragm in my alpha cb28 boiler as i had no hot water.
The hot water is now working fine but when ever i turn the hot tap off the boiler screeches and whistles, the only way to stop this is to turn the boiler of at the electric and back on again.
Boiler pressure is fine and the diaphragm was fitted by my uncle who is a engineer.....any ideas what this might be as it says nothing in the manual about screechy whictly noises.
Any help would be appreciated...Thanks.
