Self-cleaning pool
system
There is a group
of jets at the bottom of the pool. With this type of self-cleaning
system, the jets push the dirt from the shallow end to the deeper
end. There must be substantial water pressure for the jets to
properly sweep the dirt toward the deepest part of the pool so that
the main drain sucks the dirt into the filtering system.
The manner in which this system operates is by a diverter located at
the circulation area and the jets are connected to that diverter.
The water leaves the heater as it goes into the pool, it then passes
through the diverter which transmits it to the jets at the shallow
end of the pool, then
to the deeper end. With adequate pressure, the dirt will be loosened
from the bottom of the pool by the jets, and won't stick to the
floor. This type of operation will only work with the finer type of
dirt, because if the dirt particles are too large, it will clog the
main drains. Also the jets need to cover all areas of the bottom in
order for the process to work correctly.
The main source would create the greatest action, but the system
would become weaker as the jet stream moves out away from the
source. As a result, you would end up with some areas that are clean
and others than are not. The results of the cleaning also depend on
the amount of water pressure that is exerted.
This is not an ideal system because there should be substantial
water pressure and also the system puts too much stress on the
plumbing and equipment systems. As the diverter switches from one
series of jets to the next series, backpressure is created and the
circulation system becomes restricted. This type of incident can
occur several times per minute. This action puts stress on the whole
unit.
