Pool Sand Filter Maintenance & Pool Filter Problems. Avoid Mistakes & Check Your Sand Filter Pool Pump & Equipment Repairs To Reduce Your Pool Maintenance Cost.
Sand pool filters will have what is known as a “Multi-Port Valve”. This valve is an all-in-one valve that makes your pool life a little easier.
If you're not familiar with a Multi-Port Valve please read the following and/or consult your owner's manual concerning your sand pool filter maintenance.
If your swimming pool motor (pump motor) is on and you decide to start turning any valves, that could cause all kinds of swimming pool filter problems.
Be sure the filter pump motor is off before turning anything.
The settings on this type of valve are as follows:
This is the normal setting for the valve. The pool water is drawn through the pump, passed through the filter, and is then returned back into the pool as clean water.
This setting is used to flush out the filter when the sand filter media becomes overloaded with dirt and debris. Water is drawn from the pool, is passed through the filter sand and then exits out of the filter as dirty water. A high pressure sand filter means it's time to backwash
Once this part of your swimming pool sand filter maintenance is accomplished your system is ready to rinse. DE pool filters will need to recharge your grids with fresh DE.
This setting is used to flush out any dirt, debris, or excess pool filter sand that may remain in the lines after backwashing and only requires about 10 seconds. This water then exits as waste and not back into the pool.
This function allows for the pool water to circulate without passing through the swimming pool filter sand again. To be used when chemicals need to be mixed in the pool.
This setting runs water from the pool directly to the drain and can be used when lowering the water level, when certain adjustments are needed, or when vacuuming large amounts of dirt.
This setting is to be used ONLY when the pump motor is off. Closing this valve while the pump is running could seriously damage your pool water sand filter.
Use the Closed setting when:
If you have any questions or are not sure about the Multi-Port Valve or any part of your sand water filters, check with your local pool store and find a qualified pool technician.
Backwash Sand Swimming Pool Filters
For proper care of your inground and above ground sand filter, and to keep your rapid sand filter running at peak performance, you need to backwash your filter when the pool system calls for it.
This is normally 8 - 10 Psi over the "just backwashed" pressure. Here's a normal backwashing cycle for a swimming pool sand filter.
Once again, if you're even the least bit unsure of performing any part of this pool sand filter maintenance, check with a qualified pool technician.
The entire process should take about 5 minutes, a little more for commercial sand filters.
Pool sand filter maintenance is just easy pool maintenance. A swimming pool sand filter is pretty bullet-proof if you take care of it.
Swim and have fun.
