Hi
Hope someone can help. My Heatrae Sandia Megaflow Cylinder has developed a bit of a problem. The pressure gauge is showing max pressure and the cylinder makes a dull thumping noise every 10/20 seconds.
The problem began a few weeks ago. To start with, heating the water would cause the pressure to go to max. Flushing a toilet would bring the needle back to normal but would then slowly rise back up to max. If I used all the hot water in the cylinder, the needle would stay in a normal position but when the hot water came on again in the morning the pressure gauge jumped to max again.
Now, not even using all the hot water keeps the needle down.
The cylinder is about 9 years old and is model CL170.
I am about to get a plumber in but was wondering if anyone has any advice about what to expect; has my Megaflow bitten the dust?
