I am assuming you mean 1.5 horse power pump..
Pumps do not take sand, the filter does. I would need to know the make and model of the filter to tell the amount of sand
The amount of sand in a pool filtration system depends on its size.
The pump should be of when moving the sand filter control
A small sand filter 40-60 sq ft. and a small pump 3/4 HP
yes you can, the sand pump cleans the pool, making it look amazing!!
@ 1:5 mix, 15 cement and 71 25kg bags of sand (1,175kgs)
What is a normal operating pressure for a jacuzzi sand filter for an above ground pool?"
Yes because the algae can clog the pump from pumping because the algae may start to grow around it then in it
The flow will be restricted and you will have to run the pump longer and this will shorten the life of the pump. Above 50PSI you run the risk of causing the case of the filter to explode. Hatawa
Do not put sand in your pump. If the sand your are referring to is in your pool filter then it should be changed every 4 to 5 years.
THis indicates that the pump is struggling to push water through a dirty bed of sand when on filter. When on recirculate, the water bypasses the sand and flows through the valve back to the pool. Change your sand or run a cleaner through it.
15 * 5 * 0.5 = 37.5 cu ft. or 1.39 cu yards.
That depends on the thickness of the layer of sand required.
