    Drain water after rain

    I am a new pool owner. I have a fiberglass/in-ground pool with a Hayward pump and a Hayward filter Star-Clear Plus Cartridge Filter model C12002. We are receiving a lot of rain here in central Florida and my pool water level is above the accepted level. I need help on how to drain the pool. I do not see any backwash capabilities in my system. I wonder if draining can be done with my pump and my filter. Thanks.

    Re: Drain water after rain

    Some pictures of your pump pad and plumbing setup would go a long way it helping us help you. If your pump doesn't allow output to waste you could always create a simple siphon with a vacuum hose. The hose just needs to reach somewhere you can drain to that is lower than your desired water level.

    Yes, pictures would be helpful. I'm also suprised that your filter valve doesn't have a Rinse, Waste, or Backwash setting. Any of those would flush water from your pool.

    My pool has a spigot on the return side at the pad. I attach a hose, turn on the pump, open the spigot and drain down the street.

    Ok, I believe there is a drain in my filter. I am including photos of my setup. Please advise on how to drain. Thank you.

    Don't open that drain plug while the pump is running!

    It will only drain the filter anyway.

    I don't see a way to use the pool pump to drain the pool from those pictures. If there isn't enough elevation change to start a siphon, you'll need to buy or rent a pump.

    Re: Drain water after rain

    I don't have any direct experience with cartridge filters, but it looks like you could use that drain plug as a location to add a cut off valve and bleed off part of the flow. It should be a 1.5 inch NPT plug, Hayward makes a maintainable 1.5 inch valve with female threads on one end and male threads on the other that should easily screw into that hole. You can then get a roll up "blue" discharge hose that will connect to the other side. Or if you want something more durable, you can often find out of certification date fire hoses that have never been used from cabinet installations on ebay for $25-$40 which is the same ballpark price as the thin blue hoses (maybe a bit more), just beaware fire hose threaded connectors don't usually use standard pipe thread so you may need a $10 NPT to NST or NH thread adapter.

    p.s. correction after looking at the parts diagram it looks like the plug is likely 1/2 or 3/4 inch, not sure if it is before or after the filter cartridge though, since it has an o-ring it is also likely parallel thread, still Hayward likely has a drain valve replacement for it, too many people have indoor mechanical rooms that require remote draining for them to make a filter that has to be drained directly.

    Hello Richard320,

    I am attaching another picture of the pump maybe that will help. Thank you.

    Re: Drain water after rain

    Can take a picture of the top and left side of the multiport that comes out of the top of the filter?

    If there's nothing there that can help you could insert a tee and valve on the long piece of PVC that goes across from your pump output.

    Re: Drain water after rain

    Fixed this problem by buying a $60 pump. These pumps are used to drain water from any place. It's working good so far. Thanks for all the suggestions.
