Sand filter sight glass – when to replace it
The sight glass is in the water path and is under constant pressure. It may crack, become cloudy or start to drip. Then you cannot see the backwash water clearly. The seal also wears out.
Replace the sight glass if there is a crack or a leak. This way you will control the backwashing and not lose water.
The original set consists of a sight glass and a seal. The thread and size match the filter. That is why the connection is tight without additional sealants.
How it is installed
- Switch off the pump and release the pressure.
- Unscrew the old sight glass from the valve.
- Remove the old seal and clean the thread.
- Fit the new seal and screw in the sight glass.
- Start the pump and check for leaks.
Advantages of the original part
- Exact match with the dimensions and fixings.
- Quality selected by the manufacturer.
- Easy and quick replacement without modifications.
- Peace of mind that the part fits your model.
- Lower risk of repeat repairs.
How to choose the right part
Check the model of your equipment. Compare it with the list above. If you have a code or a photo of the old part, compare them with ours. If in doubt, write to us and we will help you choose.
Tighten the sight glass carefully and by hand only. The transparent plastic is sensitive to excessive force.
Check the small details at the start of the season. One worn component often leads to a bigger problem. That is why it is a good idea to keep a spare part at hand. This way the repair takes minutes, not days. Baseini.NET offers a wide choice of spare parts for pools, including valves and parts for filters.
Not sure this is your part?
Send us the model of the unit and a photo of the old part. We will check compatibility before you order.
