Turn off the power before investigating the source
of any problem in your pool system.
Handle pool chemicals with care:
read labels and heed warnings. Date chemicals as you buy them.
Use a separate, clean scoop for each. Don't mix chemicals-old
and new versions of the same chemical or different types of the
same chemical can ignite, produce toxic gases, or explode.
Don't add chemicals to the pool
if people are swimming.
Store chemicals in a cool, dry,
well ventilated area out of the reach of children. Don't stack
containers; separate liquid and dry chemicals.

pump circulates water through a filter that collects large dirt
particles. When the filter becomes clogged, water flow is restricted
and the back pressure, measured in pounds per square inch (psi),
rises above normal. Check the filter pressure gauge every day; when
the pressure exceeds the level suggested by the manufacturer, shut
off the pump and clean the filter. Three media may be used in pool
filters—diatomaceous earth (DE) in a fabric grid, pleated
cartridges, or sand. Each requires a different cleaning method,
as shown below. CAUTION: Open the air valve and let the pressure
drop to zero before unclamping a filter unit.
To keep pool water healthy with a minimum
of chemicals, make it a family rule to shower and use the bathroom
before swimming. Body oils, sweat, suntan lotion, and urine eventually
clog filters. As they accumulate, they make the water murky. To
neutralize these organics, try a chlorine shock treatment: Put 5
to 10 times the normal amount of chlorine in the deep end of the
pool with the pump running. Allow the pump to run as long as the
chlorine manufacturer suggests before allowing swimmers in the pool.
keep the pump running when people are swimming. The circulating
water holds debris in suspension, so that it will get trapped by
either the filter or the skimmer basket.
pumps are used to circulate pool water, drain basements, and circulate
hot water in heating systems. In a centrifugal pump, an electric
motor rotates an impeller to move the water. Most pumps are self-priming
(the housing automatically fills with water when you turn the motor
on), but check the owner's manual to be sure.
most common pump problems are a worn impeller and a leaking shaft
seal assembly; either part can be replaced (see below). To avoid
trouble, keep the air vents on the pump motor clear of debris and
regularly clean out strainers or filters in the suction and delivery
lines. To prevent cavitation (noisy air pockets in the moving water),
keep lines and valves into and out of the pump clear and fully open.
