Please help me get my fountain working again

My suggestion would be to cannibalise the cheapest nastiest solar powered fountain pump that you can find and use silicone fuel pipe for the actual connection between pump and head. Any old wall wart will do as a power supply.

You might have to limit the current. The one I got for doing automatic watering could throw water 6' into the air when on a proper 12v supply instead of the 6" it managed with a poxy solar panel. Caught me out!

what is 6" and 6' ?

Why would you use a submersible pump? You're running tubes through the wall anyway, might as well keep the electrics on the inside. Something like

I have a solar-powered pump, which pumps water from a large pot at the bottom into a small pot at the top, to trickle down through a series of pots. The idea was to use it, to help mask noise - which it does quite effectively.

A tiny pump/motor sits in the bottom pot, with a small plastic feeding up to the top.

Something similar, is all you would need - look on ebay.

Aquarium supplies - small bore plastic pipe for air lines etc. Micro irrigation pipe for watering plant containers etc.

Standard UK nomenclature for 6 inches and 6 feet.

Last I looked you could get a tiny submersible for £4 from China. I tried one, no problem. 3 or 4 watts iirc, produced more than a trickle.

You will find that if the area is warm the water dries up very much more quickly than you might imagine. Anywhere you could hide a small header tank, recalculate into that and then the low pressure gravity feed would be closer to what was there?

Where I was staying over for a couple of weeks in the summer there was one of those solar power fountains with quite a large tank of water. The tank had to be topped up daily. I guess the main loss of water was it splashing on the warm/hot (artificial?) stone surround and then evaporating quickly.

My experience with smallish pumps supplying re-circulated water outside is make sure that you have a filter as algae can block inlets quite quickly in summer months.

That's a good point. The way I was looking at it was any leaks will be in the pump/joints. So, have all that outside, in the pool of water.

But, I will definitely think about what you suggest.

Slightly annoyingly, that particular one takes two different sizes of tubing for input and output.

Thanks for all the very helpful comments.

also make sure, if you are in a hard water area, to used softened or rain water. Evaporation leaves a nasty deposit in hard water areas,

Phew!, I thought this was going to be a prostate problem!

From the Spinal tap Wiki :-

"Nigel suggests staging a lavish show, and asks Ian to order a Stonehenge megalith. However, Nigel, rushing a sketch on a napkin, mislabels its dimensions; the resulting prop is only 18 inches high rather than 18 feet, making the group a laughing stock. The group blames Ian, and when David suggests Jeanine should co-manage the group, Ian quits .. "

If you relocated it to your bathroom, you could use it as gents urinal

Got that to think about, too.

it might get so used anyway, if you're in town

One advantage of a submersible pump is that there are some very cheap ones about intended for small solar powered fountains. Being submerged allows it to dissipate heat as the water flow is a great heat sink.
