No hot water on gravity system?

Easy fix if there's a mixer tap with no check valves below , all youl need is maybe a towel to wipe your face dry lol

?????

Put your hand over the spout of the mixer tap and open the hot first , then open the cold , because your hands over the spout it forces the cold up the hot side in turn moving any air , if that's the problem this should help mate, you might get bit spray on your face but it works lol

If it's the gate valve then there will be spray lol

No water through the tap? Scaled up hot water outlet on the vessel. Not heating up on the gravity circuit? no water in the primary flow and returns.

More likely to be an air lock as whoever did the work previously wouldn't have left it not running.
Blow the mains up through the hot

You're kidding right? I've had snapped gate valves left by many a previous plumber. Last one was just before Xmas. Shower pump not working properly. It was surging, I diagnosed some sort of blockage and found the gate valve on the cold feed snapped and almost shut but apparently the handyman that did some work when the problem started hadn't touched it! Must be a poltergeist then.

If it is an airlock, easiest way of clearing it is wet vac on the hot tap.

As previously stated it will be due to recent works. Old vent pipe could be hovering at the water level in the new tank or something daft like that.

with you all the way........until the wetvac bit! i bought one about 3 years ago cos of everyone on here telling me it would revolutionise my life. dont know why but i cant bring myself to use it, never have and quite possibly never will.

Rubber cones that you stick up the cold feed and vent. They vacuum the system, so you can change the gate valve with the tank full.

You bung it in the vent also?
I change a gate valve once but just bunged the outlet in the cwsc. I didn't bung the vent? Was I lucky? I thought bunging the vent may cause the tank to implode? Sure I've read it on here?
