Hi have a hayward ec30 earth filter and the bump handle to regenerate the earth is limp it has no resistance at all with the filter on or off..any answers thanks?
Not sure with an EC30, I have an EC45 but assuming they are
similar make sure the steel rod in the center top is attached to
the bump handle.
With an ec45 you can detach the top of the canister fairly easily and inspect the rubber gasket and fingers inside. look for a tear in the gasket, but you'd probably get D.E. going into the pool if this was the case.
Why would the DE powder go straight through the filter and into the pool with an old Hayward DE filter ReGenX system?
What effect does the series resistance of a capacitor used in a capacitor filter have on diode current and ripple voltage compared with an ideal capacitor of no resistance?
What should you do if after vacuuming your pool the hayward filter will come on but won't circulate backwash or do anything?
Depending on the size of the pool and the size of the filter and the amount of times you have to backwash, also if you have had a lot of rain then you may need to backwash more than usual. If you put the pool in and the filter and you know how old the sand is, if you are backwashing more than usual,change the sand. Also before you backwash check the pressure of the…
Before I changed my filtration system al together I used to have a cartridge filter that as it turned out was not big enough to do the job properly, I ended up putting another filter in parallel to it and it totally fixed the problem and wasn't hard to do. It increased water flow and reduced the number of times the cartridge needed cleaning.
My husband and I just went thru this to no avail.... luckily my sister had the same hayward multi port valve and her sticker was still in tact. So on that note.... 12 o'clock is filter, 2 o'clock is waste, 4 o'clock is closed, 6 o'clock is bachwash, 8 o'clock is recirculate, and finbally 10 o'clock is rinse. we used fingernail polish to mark the positions, in case we forget again next spring.... Good luck
Time constant in an RC filter is resistance times capacitance. With ideal components, if the resistance is zero, then the time constant is zero, not mattter what the capacitance is. In a practical circuit, there is always some resistance in the conductors and in the capacitor so, if the resistance is (close to) zero, the time constant will be (close to) zero.
If you have a sand filter or a D.M. earth filter inside the filter housing is spent or needs to be replaced replace the sand or remove the top of the filter housing and id you have ropes they are D.M. earth just by removing the caked on D.M. earth will not solve the problem you have to soak the ropes in muratic acid for at least eight hours min.
