So pool is installed and running finally. Now I am trying to learn the quirks of my new system.
Here is my equipment breakdown along with a picture of my pump set up to help.
Intelliflo VS-3050 Pump
Hayward Sand Filter
Aqua-Rite TC-Cell-9 (Not turned on currently)
2" PVC Piping and Valves Throughout
Ok here are a few issues I would like some help with.
1. Flow - So I bought the Intelliflo to be able to vary the flow for cost savings and a water feature. Due to start up I have been running the pump in the the Speed 3/Speed 4 range due to cleaning etc. Now that the pool is clean and the concrete in I switched the speed down to Speed 1 (1/2 horsepower) for day to day cleaning. When I did this the pressure gauge on my Sand Filter went from this:
And it went to zero, no pressure. Now the pump is flowing and the returns has pressure, I assume this is just because of the upsized 2" piping that there is just no back pressure in the system. Is this an issue with filtering or anything?
2. Air in the pump glass - Normally the pump glass is solid with maybe just the tiniest bubbles. But when I go through the backwash cycle, rinse cycle I end up with a lot of air in the pump and line to the point it actually blows out of the returns. I am pretty sure I have a small leak right on top of my pump as I have found some water there between the pump and the sand filter. Is this the cause or is it just that backwashing sucks some air into the system?
