FAQs

Why does sand get into my system/pool?

Check the laterals inside the filter for damage. Check the air bleed tube for cracks or splits.

How often should I change the sand in my filter?

Under normal operating conditions, residential filters need the sand changed every 4 – 5 years. In areas with high air contaminants such as dust, leaves or any condition that requires frequent backwashing, the sand may need to be changed every 2 – 3 years.

For filters used on other applications, see Filter Sand Service Information Leaflet in Download section.

How often should I backwash?

Under normal conditions, once every 2 weeks. The pressure gauge on your system indicated when backwashing is required. The more dirt trapped in the sand bed of the filter, the higher the pressure will become.

What should I do to close my pool down for winter?

We recommend you contact your local pool professional as the system will need to be drained of water in the event of freezing weather conditions.

What do the different positions mean on the multiport valve?

Filter – Water flows from the pump to the top of the filter, through the media, out the bottom of the filter and returns to the pool.

Backwash – Water flows from the pump to the bottom of the filter, up through the media, out the top of the filter and out the waste line.

Rinse – Water flows from the pump to the top of the filter, down through the media, out the bottom of the filter and out the waste line.

Waste – Water flows from the pump directly down the waste line.

Closed – All ports are closed – no water can flow.

Recirculate – Water flows from the pump directly back to the pool, bypassing the filter media.

Winter – Should only be used when the system has been winterized. Leaves all ports slightly open to enable air to vent from the system.

How much sand does my filter need?

Refer to the Filter Sand Service Information leaflet in Download section.

Why has the pressure increased on my system?

Your filter may need backwashing. If the pressure rises again shortly after backwashing, replace the sand.

Can I buy products or spare parts directly from you?

Only if you have a trade account with us. Our products are supplied to distributors who then supply local pool dealers. Please contact your local pool dealer who will be able to help.

What media should I use in my Waterco filter?

My filter has just been installed and it's leaking. What shall I do?

I have a Waterco pump, how do I connect it up to the mains electricity?

The connection details are underneath the connection box. All electrical connections must be made by a licensed/qualified electrician. Check with the regulatory authority in your country.
