A have a Jandy Pro Series Stealth Variable Speed 2.5 HP pump motor on my pool
Also have a Polaris booster pump to power the Polaris
Also have a Jandy Pro Series Stealth 2.0 HP that powers 3 sheer descents and a bubbler (seems like a lot of HP, but it's what builder installed)
Here's my question...on the Main Variable Speed Pump, I've always run it on "high". My pool is 2 years old. Pressure at DE filter at it's lowest is around 21-22, and I back wash when it gets at about 28.
Today, for kicks, I changed Main Pump to "Low Speed" on my iAqualink pool app. Pressure at filer drops to around 4 from a current reading of 22 when on high. Is this the normal difference? Noise difference is huge of course, but I'm worried that on low it won't properly circulate my water.
Hoping there are many people here more knowledgeable than me that can help!
