Reducing wasted water during vac cleaning

[RonPace]

I spent the weekend pool cleaning that involved a complete suck across the bottom to get all the fine silt out.

Often this is not a 'waste of money' problem as it also lowers the water level for replenishment to counter excess CYA build up. However, this year my CYA is very low, so I was in a hurry so as not to waste too much water. However, I was particularly concsious that my pump was discharging water at a pretty high rate. So I got to wondering for vac use, there should be a stand alone product, like a giant domestic vacuum cleaner, that does not suck so much water out yet still be effective at sucking up the silt.

I tried my mate Mr Google, but he was not much help - is there such a product? I then wondered if there is a vac head with a reducing device that might perform the same job. Again Mr Google got a bit confused, so thought maybe ask her is better!

Ron there are several options for stand alone battery vacuums.

A variable speed pump saves a lot of money on electricity whilst filtering and is very handy to reduce the flow for vacuuming. Its about the only time you actually get the stated flow through the pump as its not filtering but it gets rid of the water too quickly.

So Teapot, what is filtering capability of these cleaners?

Problem here is that often we gat a heavy rain that deposits half the Sahara Desert on top of us! Theresult is that the pool ends up with a really fine silt that will sift through everything, hence it is best to hoosh it out to waste.

Yes, I agree a pump with a dial that I can turn to low throughput would be great, but not feasible now!

Hi Ron,
The poolblaster max have an extra fine filter bag to backup the regular one and it works quite well. Same with the volt range as they are made by the same company but the volt is an updated and better version. It would catch most fine stuff but the superfine pollen will make it through sometimes.
The last one is a bit course on filtration.

A pump you can dial down is feasible, just add a variable speed drive. Would pay for itself after a season or worst two. The clever pump inverter or invertek opti drive E3 would fit the bill, they are two I have used, maybe there are more now, I haven't looked for 3 years.
How I dealt with the sahara sand or very fine pollen. Turn the pump speed down so it lifts the dirt but doesn't cause breakthrough and line the skimmer basket with a cotton towel ( not washed with fabric conditioner) scrunched up. Using an iris plate (certikin) and vacuum on filtration, that caught most of it in the towel rather quickly clogging the towel so often a second was needed, wife won't mind! However this year I am switching the dryden aqua AFM Glass filter media for the new AFM ng as it filters ( at the correct flow) to 1 micron so should catch all the dirt, pollen and sahara sand easily.
