    Impeller rubbing on diffuser

    As long as there is no major damage and you still get the same output and no more rubbing, I don’t see a problem. If it were me, Only if it’s out of balance and the output seems reduced would I worry too much.

    Green pool, not algae.

    If people will buy it, they’ll sell it. Anything for a buck.

    Leslie's Salt Update?

    Someone here years ago wrote that water softener also works for a salt water pool. Still true?

    Pool pump noise

    I have a single speed pump that can be a tad noisy, and sometimes I get a resonant vibration plastic base to the substrate base. I got one of those foam rubber pads that one puts on a concrete floor in a workspace, cut it to just a bit oversize and put it under the plastic base. Voila, pretty quiet.

    cartridge filter clogged?

    Yeah, once the water flows the salt will dissolve PDQ.

    Air leak gets worse at lower pump speed

    @PoolStored: Oops! Forgot abought behind the impeller back the space would be connected to the outside of the impeller, the pressure side. My bad. I wonder if maybe the pump drain plug o ring may be leaking under vacuum.

    cartridge filter clogged?

    Your cartridge should be on the pump discharge, so when it clogs, the pump pressure should increase up until it gets to pump shutoff head. If you have zero pressure, sounds like you ended up with a plug of salt in the line somewhere, preventing water getting to the pump. Hopefully, it dissolves...

    Air leak gets worse at lower pump speed

    Sounds like it could be the pump seal since you always have bubbles. This is the seal where the motor shaft goes into the pump housing. The shaft will be at the vacuum part of the pump, if the seal is worn, it could allow air intake.

    Replacement filter cartridge

    Actually more square feet is good, more area for water to flow through, resulting in a bit more flow, and a bit less pressure. More area to catch more debris means it’ll clean a bit longer before you need to rinse it. The important thing will be the fit; outside diameter, inside diameter...

    Test Kit Issue

    My speedstir is about 15 years old, the unlit button no longer works, the lit button has the membrane worn off, but it still works like a champ. I don’t buy batteries anymore, I use rechargeables I got with high capacity amp hours. Use it year round for the pool and the fish tank, recharge the...

    booster pump issue...

    Yeah, that cartridge is the only thing that removes the algae and other fines. Rinsing with a hose on stream should enough rinse and get it back inline. I have a Sta-Rite cartridge only a couple feet from my AG pool, the pressure runs about 5 or 6 psig when clean. If it’s clogged with sunscreen...

    booster pump issue...

    There are only three things I can think of. I’ve never had a booster pump, but from the parts diagram and flow diagram, the pump is not self priming, the filter pump must be on, and the valve lineup must supply water from the filter pump to the booster. Is the booster getting water? Maybe remove...

    From Swamp Green to light green and cloudy

    Looks just like my pool days ago. Persevere, just takes time for the filter to get it all.

    Rust Water

    Filling from a fire truck, the water typically comes from a hydrant, which comes from the city water piping. With domestic use the flow is usually slow. Then when the truck fills, it creates a flow of a few hundred gpm, so it stirs up rust and sediment from that iron piping. For firefighting...

    No CYA after cleaning algae

    I usually have no CYA when opening the pool in the spring, use the sock method each year, takes a couple weeks to get it up. pH started at 8.2, the stabilizer reduced it to 7.5. You might consider waiting until CYA is up to snuff before adding MA. The CYA test mixing pool water with the melamine...
