I am looking to install an electric 2" ball or slive valve to my skimmer line , it feeds into my drum filter so my way of thinking is during the day it will be shut stopping food going to waste. let's say at 10 o'clock pm it will open then at 6 o'clock am will shut just before the first feed , all this will do to the drum is pull harder on the bottom drains . If anyone has seen theses valves or know where I could get them from please could you pass the information on .
Ball valves cost a fair penny, it would be fairly easy to modify a slide valve to be automated, some ideas here to show what I mean, or just buy the kit. They don't seem to cater for 2", but a 3" with reducers should do what you need, or modify the kit to suit a 2" valve.
I like the idea of the air curtain but you know me dave I like a toy, so I think I ll be going down Al s route with the George Fischer type ball valve . If we look at the ball valve do you think it will be easy to program it to open and close once a day ?
Cant see a problem timing wise but Al is the Guru in this area
One thing though, not sure how tight you are playing it with the cleaning probe level, if you cut the skimmer supply and there is an extra head loss in the drum you need to be sure the probe is set high enough so it doesnt go into permanent clean cycle..
Ryan, not sure on how the GF valves work, will look into them. Timer wise isn't an issue to sort something out, you could run it like mine if your using an autofeeder, when the feeder feeds it could trigger the valve to shut for say 20 minutes and then reopen. Anything is doable with a couple of relays, and a bit of wire
