    Kreepy Krauly Problem (slow)

    I've been trying to figure this problem for 2 months and still no solution. Here is my set up that hasn't changed for the past 2 yrs:

    Run with low speed pump
    vacuum hose instead of KK hose
    main drain (through skimmer) plugged
    KK Vac Plate
    skimmer sock
    filter pressure is very low, almost zero (with new bigger cartridge filter replacing the old DE)

    Everything was running fine until one day, afte a swim, I put the KK back to the pool and next morning it didn't move. The KK was really old with worn out seal and probably gaps in the swivel head assembly. I changed new seal and and head, it moved again but very slow. I bought a new unit (mainly because of the rebate) and it didn't move any faster. I notice when it climbs the wall and when I pull the hose up (not too far from the unit) it speeds up. Cleaning pump basket and filter didn't seem to help much either and no air in the filter, so no leak. And I think because it's so slow (weak suction?) it keeps going in the same pattern (can't fight the weight of the hose?). I had the hose sit in the sun for 2 days to make sure it doesn't coil.

    So nothing was changed, why does it slow down?

    My other question, which I've been wanting to ask is why is it every time I clean the skimmer sock, the KK runs slower for a day or two until it collects enough dirt/debris in sock. Shouldn't it be faster instead with stronger suction when the sock is clean? It's alway been this way even before I have the problem above.

    Have you checked the impeller to see if it's partially clogged?

    The impeller of the pump? no and I'll do that.

    Honestly, I am kind of surprised that the KK worked at all on low speed ... I did not think there was typically enough suction.

    That's one of the things I suspect. Even if it worked, it probably had barely enough suction power so any less would slow it down. There were times when it slowed down because of the dirty filter and cleaning it brought it back to speed.

    Update: This is my conclusion: I bought my new 2 speed pump together with the cartridge filter and it was working fine with the lower speed. Now that my filter is no longer brand new and cleaning the filter can never bring it back to brand new condition, the KK will not work at desireable speed. Now I have to use full speed and even with half the running time, I'll probably see an increase in power use. With full speed on the Whisperflow, it moves alot more water compared to old pump with same HP (1, I think). I wish I bought a one speed but less powerful pump, like 3/4 hp instead, which cost less and save $ on utility. The advice of buying a less HP pump to replace a 10-20 yrs old pump is right on.
