I'm a new pool owner... again... and going through initial start-up. I have 3 pumps on my pool.
1. Filter pump.
2. Spa booster pump for jets
3. Water feature booster.
The filter and spa pumps are working quite well. My 1.5HP water feature pump is pretty noisy and it runs louder than the 3HP spa booster. All the pumps are Jandy Stealth models with the filter pump being the ePump. Anyway, I think I know what the problem is, but I'm looking for confirmation. See below:
The water feature pump sucks water through a separate drain in the pool and supplies water to 3 things: Two separate sheer decent waterfalls and 1 return inlet in the spa to add more water to spa's cascading waterfall. This pump is loud and doesn't run smoothly. There is no cavitation, but I can see several tiny air bubbles through the window. I think my problem is that the plaster company put a anti-vortex drain cover over the 2" return in the spa. Would that cause back pressure and make the pump struggle?
Oh.. another interesting phenomenon on the water feature plumbing. After you turn the water feature pump OFF the sheer descent waterfalls continue to run through some awesome siphon action. No electricity and perpetual waterfall. While this is kinda cool, it is a little inconvenient to stop. I have to go manually turn the valves on their return lines to shut each one off individually. What's the solution here? A auto valve actuator?
Thanks everyone. It's been quite an adventure so far...
