When the time comes to buy a new filter or just replace your old backwash valve, you have a choice to make. What type of backwash valve do you want? This article helps you sort through your options.
If you are simply looking for the backwash valve with the lowest cost to install and the lowest ongoing cost to maintain and repair, then the push pull valve is for you.
The installed cost is almost $100 less than a multiport valve, but it does have fewer features. It has only two settings: Backwash and Filter. If you want to have a rinse or filter bypass setting, then you will want a multiport valve instead.
Most people never ever use these features, so for them, the push-pull valve is just fine.
Multiport valves have one major thing going in their favor – features. Here is a list of the settings on most multiport valves.
These style backwash valves probably have the highest flow of all the backwash valves because they are a “straight through” design like a Jandy valve and the valve itself provides very little resistance to slow the water down.
These valves are less proven than the other valves and there were some issues early on. The manufacturers will tell you that all the problems are resolved (as always), but the buyer should understand that it is not as proven as other designs.
For most customers, the push-pull backwash valve is the way to go. If you must have te other features, then choose multiport. If you need the absolutely best flow, then choose the diverter style valve.
