WARRANTY
Please refer to Waterco’s warranty terms and conditions.
Above normal or
excessive force
to operate the
Multiport Valve
Scoring or jamming with foreign matter or debris. If this condition persists after
rinsing, disassemble the valve to clear dirt and debris. Continued operation of the
valve may result in a non-sealing condition (damage to spider gasket). This will lead
to water loss to the backwash line or to inefficient filtration.
Note: A filter sock is recommended during pool vacuuming, to prevent dirt and
debris lodging between the spider gasket and MPV body.
Water is not clear
1. Insufficient filtration time.
2. Heavy bathing or dirt load. Pool must be floculated and vacuumed
directly to waste.
3. Filter is dirty, requiring a thorough backwash.
4. Air leaking on suction (influent line).
5. Pump impeller vanes blocked.
6. In sufficient water supply (water level low, blockage).
7. Pump not primed.
8. In correct water chemistry.
9. Excessive flow of water for filter size. Foreign matter or debris forced
through filter bed and through the under drain.
10. Other restrictions including (pool suction cleaners) resistance from other
inline equipment such as strainers. Operating the filter on recirculate will
determine if the restriction is in the filter.
11. Clogged or channeled filter media. Perform thorough backwash or
regeneration.
Filter media
flushed out to
waste during
backwash
1. Excessive quantity of media in the filter.
2. Excessive water flow.
3. Incorrect sized or grade of filter media.
Filter Media
returning to
Swimming
Pool/ Spa
1. Filter is on recirculate.
2. Verify it is the filter media and not from another source.
3. Damage to the under-drain laterals.
4. Damaged or incorrect connections to the Multiport Valve.
5. Incorrect sized or grade of filter media.
Short filtration
cycles
1. Presence of algae or a scale build up.
2. Check water chemistry.
3. Excessive water flow, check pump size / mains water flow.
4. Filter blocked through calcium etc. clean filter media.
5. Ineffective backwash, perform thorough backwash.
High pressure on
start-up.
1. Small eyeball fitting in Pool / Spa.
2. Partially closed valve on return line.
3. Pump size is too large for the filter.
