No water

[terryboxman]

Emptied the water on last trip. Now there is nothing coming out of the taps or toilet flush. Pump is rotating, water in the tank. Suggestions?

Make sure your dump valves and your frost valves are closed. If there's air in the system, it can take more than a minute before you get good flow. But it should start spluttering before then.

Have you shut the boiler drain valve?

Sounds like an air bubble. Hope you sort it soon. It will be a simple cause

I checked all drain valves are closed. I shall persist with the tap open for longer. I will let readers know the outcome. Thank you.

The boiler takes 10 litres before it starts coming out of taps. Always takes a good few minutes, or longer if you forget to close the boiler dump valve!
Make sure you have plenty of water in fresh tank to allow for this.

You say the pump is ‘rotating’ which sounds like it is a centrifugal pump rather than a diaphragm pump. These are more difficult to prime as, until they have some liquid in them, then they won’t pump air (unlike diaphragm pumps that will) Running them dry for an extended period also risks damaging the seal.
If you are still having problems then a possible solution is to use a wet and dry vacuum cleaner attached to an open tap to try and suck the water through the pump. Leave the pump off until you can hear the water filling the system.
If you haven’t got a wet and dry vacuum cleaner then the sort of manual stirrup pump used to inflate kayaks etc. usually has a suck setting too.

If the pump is in the tank remove the large service bung/cap on the tank, insert your hand and tap the pump on the tank side while it's running.
That may/should dislodge any trapped air.
