Q: How can I fix air infiltration in my pool filtration system?
A: Air infiltration often occurs due to a loose or damaged pump lid O-ring. Inspect the O-ring and replace it if it’s damaged. Also, check for any loose clamps or bolts and tighten them as needed.
Q: Why is sand getting into my pool?
A: This could be due to a broken filter valve or damaged sand filter lateral. Inspect these parts for any damage and replace them if needed. Using the Rinse setting on the filter valve after backwashing may also help.
Q: My pressure gauge reads zero or low, what does this mean?
A: A low pressure reading could indicate a clogged filter or a problem with the pressure gauge itself. Clean the filter and check the gauge for any damage.
Q: What causes high filter pressure readings?
A: High pressure usually means the filter is dirty and needs backwashing. If backwashing doesn’t help, inspect the sand for clumping or channeling and replace it if necessary.
Q: The pressure rise is too slow/fast, what should I do?
A: A slow pressure rise could mean there’s not enough sand in the filter, while a fast rise could indicate that the sand is dirty or there’s a blockage. Adjust the sand level or clean the filter as needed.
Q: What is sand channeling and how do I fix it?
A: Sand channeling occurs when water forms tunnels through the sand, reducing filtration efficiency. This usually requires replacing the sand in the filter.
Q: How do I know if my multiport valve is damaged?
A: If the handle is loose or difficult to turn, or if there are leaks around the valve, it may be damaged. Inspect the spider gasket and O-rings for wear and replace them if necessary.
Q: What is scaling and how can I prevent it?
A: Scaling is the buildup of minerals on the filter components. To prevent scaling, maintain proper water chemistry and clean the filter components regularly.
Remember to always turn off the pump before performing any maintenance on your sand filter multiport valve. If you’re unsure about any steps, it’s best to consult with a pool maintenance professional.
