Hi Guys
Just wanted to pick your brains on this one. (I'm g3)
Customer has a 250 litre un-vented cylinder in his loft. He called me to the blow off dripping outside.
The expansion vessel had failed and it was fitted at the bottom of the cylinder on the floor of the loft. The control valve was also ancient so I replaced the control valve and re-piped the inlet so the expansion vessel was above the cylinder.
3 months on and the blow off is dripping again. With a new control valve and expansion vessel.
The temperature and pressure relief valve appears sound. When I disconnected the new blow off on the control valve its definitely coming from there.
The un-vented cylinder is quite old. 15 years +
Would a split coil present like this? They have been losing pressure on the heating side.
This would be my first split coil on unvented, I've seen quite a few open vented but not on a sealed system.
Thanks
