Maintenance: Emptying the Strainer Basket
The strainer basket should be inspected frequently through the transparent lid
and emptied when a build-up of rubbish is evident. The directions below should
be followed.
1. Switch off pump.
2. Unscrew the strainer basket lid anti-clockwise and remove.
3. Remove the strainer basket by lifting upwards from its housing.
4. Empty the trapped refuse from the basket. Hose out with water if necessary.
NOTE: NEVER knock the plastic basket on a hard surface as it will cause damage.
5. Check the strainer basket for cracks, replace the basket in the pump if OK.
6. Replace the lid and ensure that it seals on the large rubber O-ring. Firm hand
tightness only is required. The O-ring & thread can be lubricated with
Hydraslip or equivalent products.
Failure to undertake regular maintenance may cause damage not
covered by warranty.
Trouble Shooting
If the pump runs but there is no water flow or water flow is reduced, the
following condition may apply:
1. The filter requires backwashing or it is blocked. Refer to the relevant section in
the Filter Manual.
2. The pump is not primed. Re-prime as per instruction in ‘Starting the pump’
3. There are air leaks in the suction piping. Check all piping and eliminate leaks,
also check for a loose strainer basket lid. Air bubbles in the water flowing back
to the pool would indicate a leak in the suction to the pump allowing air to enter
the pipework.
4. A leaking pump shaft seal may also prevent operation. Evidence of this could
include finding water on the ground under the pump.
5. The pump is not able to get water from the pool. Check that the valves to the
pump are fully open and that the pool water level is up to the skimmer box.
6. Blockage in the piping or pump. Remove the strainer basket and check for any
blockage to the pump impeller entry. Check the skimmer box for blockage.
