Question:
What is the difference between a Push-Pull Valve and a Multi-Port Valve? - Jean, from Richmond, VA
Answer:
A pool filter’s push pool valve only has two setting has two settings Filter and Backwash. Meanwhile, multi-port valves can have 4,6,7 or 8 settings that divert and route the water through your plumbing. The most common multi-port valve setting are Filter, Backwash, Rinse, Recirculate, Winter, and Closed.
There is a benefit to the multi-port valve extra capabilities. The more settings allow the pool user flexibility during maintenance. Both valve types have Backwash but the multi-port’s Rinse setting allows you to clear lingering debris from the filter and pipes rather than sending it back to the pool. Recirculate allows you to bypass the filter media in cases where you are adding chemicals that may be hard your DE grids or sand or if you have a cracked tank but still need to turn over your water for chlorination. For more information on these valves, read out guide titled: How a Multiport Valve Operates or How To Operate a Hayward Slide Valve.
For most filter models, the price between the slide and multi-port valve options is not to drastic. WWe suggests springing for the multiport valve to give you the extra capabilities for whatever pool issues pop up down the line.
