What the Ring Does
The connector joins the hose to the pump, and the ring around it keeps the connection watertight. Over time the rubber flattens, loses its elasticity and tears easily when taken apart. The connection then leaks or the pump draws in air.
Signs It Needs Replacing
- a puddle forms next to the connector
- the pump sucks in air and runs noisily
- the rubber is crushed, chipped or broken
Replacement in Five Steps
- Disconnect the pump from the power and shut off the water.
- Remove the hose and take off the connector.
- Remove the old ring and clean the seat.
- Fit the new ring evenly into the groove.
- Reassemble the connector, attach the hose and check for leaks.
The Advantage of the Original Size
The part is made for the specific model, so it needs no modification. Substitutes often differ by a millimetre or so, and the problem comes back.
Maintenance
Before putting the pool away for winter, inspect the connections. Store removed parts in a dark, dry place, and tighten plastic threads by hand only – without a power tool. Do not combine the new ring with neighbouring parts that are already distorted.
In the Package
You receive an original Mountfield part with the number DS2920141252. Check the number and the model of your equipment before ordering. When replacing the ring, also inspect the 6×2 O-ring and the 14 mm mechanical seal; the pre-filter basket is also worth a look.
