Paintwork condition is actually quite good. It's going to need some major work on functionality, however.

Thanks Les for the pictures of the missing spout.

I still don't understand how it was supposed to work. Inside the stand below the bowl I can see the small copper pipe from the pump. It seems to extend about 1/2 "into the stand and stop. Was the entire stand supposed to fill with water before coming out of the spout? Or was that copper pipe attached to the spout.

It doesn't look as if anything was ever attached to the pipe, but on the other hand, the solder seal between the stand and the base does not seem intact for the entire circumference. This would allow for water to leak back into the pond.

Of course, if the pump is fast enough that may not matter.

Any insights greatly appreciated.

Can’t offer any advice Richard,

But damn that fountain sure looks good on your veranda.

Ever since Les first posted a picture of one of his fountains, I have wanted one of these

I'm sure Les can help you with your queries Richard

Richard, I believe the pipe hanging down at the wall is the water inlet pipe.
The piston then pumps it out the other pipe to the spout. So, to operate it,
the fountain must be filled so the water level is above the inlet pipe opening.

That is so neat,

Chucks quite right, basically the same principal as the oscillating engines, only using water not steam.

the inlet pipe is down at the bottom, as Chuck says

Richard, i think a piece of brass will need to be machined here.

Quite easy if you have access to a lathe.

I assume the copper pipe goes up into the spout. Maybe it was soldered in, but possibly silicone would seal the pipe in to the spout now

Richard,

You have two pipes connected to the piston.
One short pipes which sits below the level of the reservoir and feeds the piston.
The other which comes from the piston and then into and out of the bowl.
The bowl has no function, it is for decoration only.
The spout which is missing from yours but shown on mine is connected the the piece of pipe inside the bowl.
The way it works is the hole in the spout is SMALLER than the copper pipe. This is so that the water comes out under pressure otherwise the water will just dribble out of the spout.

Hopefully this video will help you see how it works.

mmm at first I thought that theres a missing 90 degree pipe coming into the spout,

but maybe the whole fountain inside does fill up.
The piston must generate quite a pressure for it to do that though,
and give such a spout as Leses does

If it were mine, IO woulf make a coupling of sorts to join the pipe that goes towards the fountain and the pipe that would be fitted with the spout, that way I would think that here would be no need to remove the bowl. I bet a bit of rubber tubing would make the coupling

I have run mine as you can see in the video, the pipe on mine runs from the piston through the bowl to the spout and does not fill the inside of the bowl.

Whoever did the the repair on yours did it wrong.

It looks and sounds like that they soldered around the bowl so when it ran the water only flowed over the edge of the bowl and back into the reservoir.
