Seal 30×20×3 mm for filter and solar shower

Seal 30×20×3 mm: what it is for and when to replace it

Each time a threaded connection is unscrewed, the washer is compressed and over time it flattens. Sun and chlorinated water speed up its ageing. A new washer restores elasticity and seals the connection without extra tightening.

When to replace it

• water drips from the threaded connection
• the washer is hard, cracked or flattened
• after winter the connection is not tight

Why choose an original part

The original Mountfield part is made for the specific model. That is why it fits without modification. Substitutes often differ by millimetres and the problem reappears. It is best to order the right item the first time.

Tips for long-lasting use

Before winterising, clean and check all connections. Store removed parts in a dry, dark place. Do not tighten plastic threads with power tools. This way small details last more seasons.

Regular maintenance is cheaper than an emergency repair. That is why keep spare gaskets and fasteners at hand. This way opening the pool in spring goes without surprises. The new part should not be combined with neighbouring parts that are already deformed.

How it is installed

1. Stop the water and disconnect the pump from the power supply.
2. Unscrew the connection and remove the old washer.
3. Clean the seat of dirt.
4. Fit the new washer flat in the socket.
5. Tighten by hand and turn on the water to check for leaks.
