we are setting our moho up for the summer. We have put some water in the tank. The pump is running (continuously) but no water. Anyone any suggestions?

I have previous for not closing the frost protection drain valve on the boiler.

If taps aren't open, the air in the pipes has nowhere to go.

Look at the pump, if it's got a clear plastic head on it look for air being pulled in. If it has, tighten all the jubilee clips you can find downstream, I've found that a socket or spanner is better than a screwdriver.

Is it a submersible pump, if so are you sure that 'some' water is enough to submerse it?

Try to get water through the cold taps first. To get water through the hot taps, the water heater has to fill up so that the water can come out of the pipe at the top, so it takes a couple of minutes to fill it. Assuming you've closed the drain taps on the pipes, the tank drain plug and the frost protection valve.

Ours regularly has an airlock when refilling after extended drain down.

Usually fill the tank right up with water and because it's a submersible pump, open the tank screw top lid, put my hand in, grab the pump and tap it reasonably vigorously on the side wall. Usually there's a bit of a splutter, and a change in tone of the pump as it actually starts working! Guess it sort of helps to 'prime' it and break the air-lock.

One other small detail, I usually plug in the hook-up if possible, just to give the pump a tad of extra umph (not essential)! :oops:

Once it starts pumping it works fine from then on. :giggle:

Something of a faff and shouldn't be necessary. Poor design...? :unsure:
