Hi guys, please help a brother out.
Please see signature for installed equipment.
All my pool piping is 2", except for return fittings, skimmer intake and filter fittings (1.5")
I have 3 pressure side elements:
- Bottom drain
- Vaccum piping
Normally, while filtering, the bottom drain and skimmer are fully open.
In that instance, PSI is 10 to 11
If I close the skimmer, the drain keeps the PSI around 9-10 and the pump dome is all water filled, but...
If I close the bottom drain valve and let the skimmer alone, pressure drops to 6 PSI and the pump dome is not filled entirely with water
The worst part is the vaccum valve. If I close the skimmer and the bottom drain, pressure drops to 4 PSI and water barely enters the dome.
What are the possible causes asside from piping blockage?
Is the 10PSI pressure a normal pressure for my equipment? based on my filter-pump-piping combination? the pump is about 21 feet apart from the pool.
Thanks for your help!
