Pop-up water feature not going down

[matt_s]

Anyone have these on their spa? It's a LED pop-up water thing that supposed to go up when pressurized and down when depressurized. The problem I have is that they don't go down when depressurized...

Artesian calls them Aqua-serene

Seems to be Waterway that makes them:

Good idea posting the link.  Having never seen them in real life, I would guess they depend on gravity to make them go down when the water pressure goes away.  I would next guess that perhaps a little calcification might be causing them to stick? Can they be disassembled and perhaps soaked in a little CLR?   I'll now step aside for someone who knows what they are talking about.

I have examined them and there is a gasket around the pop-up part that should make them slowly go down. Don't really understand this since you might think that a worn gasket should make them go down even faster. I have tried to lubricate them without luck. If you remove the gasket they pop right down but then the whole thing leaks water all over so that doesn't work. Maybe try to replace the gaskets then..

Replacing the gaskets should help, I would think, a slightly worn, dried gasket may stick or come out of position.

I took them inside and lubricated them with a silicone solution a number of times, after re-attaching them everything works fine!
