Now we're ready for the fun stuff. Understanding the basics of pool water maintenance fairly straight forward. However, if you're the least bit unsure about maintaining or back-washing your sand filter, it's best to call in a professional pool tech. Before making any adjustments or turning any valves, be sure the pump motor is OFF.
Many pool systems will have what is known as a “Multi-port Valve” or MPV. This valve is an all-in-one valve that makes your pool life a little easier.
If you're not familiar with a MPV, please read the following and consult your owner's manual. If you're pump motor is on and you decide to start turning any valves, well, that would be bad. So be sure the swimming pool pumps and filters are off before turning anything.
As with anything in life, there are variables. A heavily used pool will require more back-washing than a lightly used pool. When you backwash depends upon your unique situation. But as a general rule, you'll want to backwash when the pressure on your sand filter's psi gauge is 8 - 10 lbs. over the "just back-washed" or normal operating pressure. This means if your sand filter normally runs at 8 psi the you'll want to backwash when the gauge gets to around 18 - 20 psi.
The multi-port valve (MPV) 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, passes 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.
This setting is used to flush out any dirt, debris, or excess pool filter sand that may remain in the lines after back-washing 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.
Back-washing a sand filter is an easy process that takes just a few minutes. It's done by reversing the flow of water back through the filter in the opposite direction, sending the dirty water to waste.
The entire process of back-washing your sand pool filter should take about 5 minutes.
Sand pool filters are the most widely used types of filters in the world and are perfect for any type of home or commercial pool. Yes, they do require some periodic maintenance, but that seems to be part of life. Taking care of your sand filter should become part of your regular pool maintenance schedule.
Keep an eye on your sand filter's pressure and backwash when needed. Having a properly working sand pool filter is one of the keys to a perfect pool all swimming season.
