    when you vaccum a pool what does the filter needto be set to

    is it backwash? or can you just keep it on filter? if i try backwash or waste i lose to much water too quickly, but i dont think im supposed to leave it on filter either. what is the best setting for vacuuming? thanks

    For normal vacuuming you leave it set to filter. If you are vacuuming up some serious muck then you want it set to waste.

    Hey Droid ...

    Jason is right ... use the filter setting. One additional thing to watch ... as you vacuum on the filter setting if there is a lot of stuff (dead algae, leaves, pine needles, etc) you'll want to watch your filter pressure. As the filter traps more junk, the pressure will go up and the vac efficiency will go down. Just backwash it then to remove the crud from the filter and your pressures will go back down and the vac will work much better again for you.

    I'm glad you mentioned that, because lately my vacuum hasn't been doing to great. A paper near my filter says to vacuum open the vacuum valve and open the skimmer half way. I try to adjust the skimmer so that the vacuum works well but it really doesn't get much pressure no matter what. I tried backwashing with the vacuum valve open but it still doesn't work very well

    How many skimmers do you have? If you have two, try closing one completely. That will give you more suction to the vac.

    I only have 1 skimmer, so I close it half way as per the instructions, it helps but it doesn't if that makes any sense. I think soemthing might be clogged in the pipe :/ any suggestions for how to unblock it?

    A drain king, an attachment for a garden hose, is the best way to unblock a pipe. You want to run the drain king flow the opposite direction from normal flow. Turn off the skimmer completely and open the suction line completely. Open the pump strainer basket and remove the basket and insert the drain king into the intake pipe and then turn it on. Hopefully that will blow anything blocking the pipe back towards the pool.

    where can I buy the DrainKing? So this will work well enough in a complex piped system? There are so many different lines and 90 degree turns i wouldnt think this would work to well

    is this what you mean http://www.amazon.com/exec/obidos/ASIN/ ... m/kkorg-20 ?

    and would I need this one http://www.amazon.com/Water-Products-Un ... _hi_text_b ?

    Thanks

    I was thinking of this one or this one. Most any hardware store will have them or one of the nearly identical competitors.
