===== Overflow ===== | ===== Overflow ===== | ||
Overflow in the reservoir (mixing basin) is likely due to the failure of one of two valves: | |||
* Water fill via the solid tablet tank is controlled by a PurAqua PASV150B solenoid valve. This valve is electrically actuated by a a small float switch. Verify that the solenoid opens/closes (listen for an audible click) when the float switch is operated. The valve's purpose is to stop flow of water to the solid tablet tank (and ultimately the reservoir) when the water level has reached the upper threshold. Build-up of contamination on the rubber diaphragm or debris in the housing may prevent the valve from fully closing, allowing water to flow uncontrolled. To clean, remove the 1/2" bolts and separate the two metal parts carefully not to damage the rubber diaphragm. Remove the diaphragm and clean surface contamination with fresh water. Inspect for cracking, tears or other signs of deterioration. If all is deemed to be in good working order, re-assemble (careful not to over-tighten the bolts). | |||
* Make-up water into the mixing basin is controlled by a mechanically-operated plunger valve, opened and closed by a float ball. This valve is a 1-inch Kerick PT100SS (it seems that a Kerick PT100SS may work as well). This valve appears to make up the difference between outflow (via the chlorinator pump) and inflow that would otherwise only pass through the solid tablet tank. The valve may over time become damaged, or blocked by debris. Inspect and clean as needed. The valve can be purchased individually from various sources. Alternatively, a rebuild kit (p/n 9500200) or the whole assembly (p/n 9501056) may be purchased from Aquatic Source or PurAqua Products. Assuming the rod and float ball are in good condition, replacing only the valve (re-using the rod and float ball) is a good balance of cost and ease of repair. | |||
===== Pump Leakage ===== | |||
The pump shaft seal may have failed. Details to follow. | |||
