How do I identify a Hayward multiport valve?
The easiest way to identify your multiport valve is to find a manufacturers part code, this is normally found along the front face of the multiport valve. Once you have identified this number we can then use it and match it up to a valve that suits your pools filtration system.
Are multiport valves interchangeable?
Multiport valves fit only certain specific filters, and are not interchangeable among filter models or brands or filter type.
How do I know if my multiport valve is bad?
One common symptom of multiport valve problems is when there is leaking around the valve itself, or when water comes out of the waste line, even when the valve is set to the FILTER position. Multiport valve problems may also be indicated when dirt fails to be trapped by the filter, instead returning to the pool.
When should multiport valves be replaced?
Spider Gasket Replacement: Every 5-10 years, the gasket on a multiport valve may need to be replaced. First, make sure that you order the correct spider gasket, there are literally dozens of different sizes.
Should all valves be open on pool?
From left to right, they are SPA MAIN DRAIN, CLEANER, SKIMMER, and POOL MAIN DRAIN. For the cleaner to operate at maximum efficiency, only the skimmer and cleaner valves should be open. No other valves should be open. So it is either main drain+skimmer or cleaner+skimmer.
How long does a multiport valve last?
If the valves are older than 10 years you may want to replace the whole thing versus replacing just handles. Multiport valve manufacturers build their units to be rebuilt, and as long as the main internal parts are okay, the wear out o-rings and gaskets can be replaced.
Do I need to glue my spider gasket?
It’s not a glue, just helps make things water tight. Also, the flat side of the spider gasket should be on bottom. The lubricator seals the gasket but at the same time will make it easy to replace when needed. I hope this helps.
How do I know if my spider gasket is bad?
If your spider gasket becomes worn or torn, or twisted or happens to pops out of the groove in the valve body, this allows water to creep and seep from one port to the next. You may not notice water bypassing the filter, and returning to the pool without being filtered, but this can happen.
How do you fix a leaking multiport valve?
If it’s still leaking, remove all cover screws and pull out the key assembly. Clean, inspect and lubricate the large cover o-ring and place back into the groove in the key assembly. Replace the key into the valve and tighten up the cover screws, then fire-up the pump to check for leaks.
