Restricted plumbing lines, such as kinks in hoses or closed valves, can also contribute to low pressure. Furthermore, a dirty or malfunctioning pressure gauge itself might provide an inaccurate reading. Consider replacing the gauge if suspected. Finally, channeling within the sand bed – where water finds paths of least resistance – can reduce overall pressure. Addressing these issues promptly will restore optimal filter performance.
Water Coming Out of Backwash While on Filter
Experiencing water discharge from the backwash port while the filter is set to “Filter” signifies an internal issue within the multiport valve. This typically indicates worn or damaged O-rings, preventing a complete seal between valve positions. The valve directs water to the waste line (Port A) during backwashing, and a faulty seal allows this to occur even in filter mode.
Immediate action is required to prevent continuous water loss and potential pump damage. Replacing the top and bottom O-rings is often the solution; remember the bottom O-ring is slightly smaller. Inspect the valve body for cracks or damage as well. A complete valve replacement (SP0714T for S210T models) might be necessary if the damage is extensive.
Reversed Water Flow Through the Filter
If water flows through the filter in reverse – exiting via the waste line while on the “Filter” setting – the multiport valve is almost certainly the culprit. This means water and dirt are bypassing the sand bed entirely, rendering the filtration process ineffective. This condition mirrors symptoms of water exiting the backwash port unexpectedly.
The primary cause is a malfunctioning multiport valve, specifically compromised internal seals (O-rings). A thorough inspection and replacement of both the top and bottom O-rings are crucial first steps. Ensure correct sizing during replacement. If the issue persists, the valve itself may be damaged and require complete replacement. Check for debris obstructing proper valve operation.
