Usually the pressure gauge on your pool equipment indicates how much pressure there is before the filter. as the pressure goes up it indicates that the filter is getting blocked and needs a backwash or cleaning. while the pressure is low the filter does not need cleaning.
no
one and a half horsepower.
The pressure increasing indicates that something is blocking the filter.
A pool pump motor which is drawing half the amps listed on its nameplate can indicate a problem with the windings or a lack of incoming current. Pumps will only draw as many amps as are required to operate under the current load.
Not necessarily, it depends on the condition of the original pump. It may have a worn or warped impeller. I would look into making sure the original pump is in good shape.
Main reason for pump seal (mechanical seals) in a pool pump any pump for that matter is to contain liquid (water in this case) in the pump and hold prime and pressure. Other reasons, lower friction,reliability it can last for years.
A pool pump should only be replaced if and when it fails. A pool pump needs proper maintanance in order to function properly,and should last the life of the pool ith proper care.
No. generally a booster pump is used to run a pressure side cleaner.
Normaly pool pumps have only one speed " flat out" unless you have a two speed pump.
Yes you can.
When vacuuming a pool manually a loss of pressure can be caused by something getting stuck in the hose. A leaf or a large bug can get stuck in the hose and cause it to lose pressure.
It is a great pump. It isn't only quiet but it also produces the highest water flow offered by any pump.
