Swimming pool cleaner/filter Answered

Hello, I have an old (about 50 years) 50.000 liters (13 208.6026 US gallons) swimming poll that doesn't have any kind of cleaning or filtering machinery (if you know what I mean) so it's just like buried water tank :). The problem is that it's often filled with grass, leaves and bugs that sink to the bottom of the pool and I don't know how to get rid of them. I have a water pump that I use to empty the pool that takes about 2 liters/second that I'd like to use to "vacum" clean the pool floor but I don't really know how Any ideias? thanks!

here they are...the drawing is bad but I's a standard water pump ( i think) and you know how it works! I'd use an electric motor (that would be off the water) to turn the paddles. Do you know how "powerfull" a dishwasher water pump is? I could use one instead of building the sistem in the image! p.s. Sorry if you don't understand some things that I write, english is not my main language!

Ah, I didn't realise you were thinking of a permanent installation.

That should work well, as long as it is waterproof. I believe there is a special kind of cement or mortar for swimming pools - you had better find out about that.

(Don't worry about poor English - most people here are Americans, and won't notice!)

I believe that it is going to work so it's ok to be permanent!

I thought of it overnight and I doubt my family will let me drill the pool wall. It's an old pool and the pressure those walls sustain is huge, I'm affraid that drilling two big holes in it might compromise it's resistance (well I doubt it but I'll only do that if I know my sistem really works).

So, I had to think of a solution...here it is:

Notice that there are 2 sets of pipes (you can only see one in the drawing because it is in front of the other :) )

When I want to 'start' it I just have to take off the lids (Don't know if that's the word....something that won't allow water/air to pass) from position 1 and put them in position 2. Then fill the pipes with water (with a bucket or hose), start the pump and remove the lids from position 2 back to position 1 (I'll probably have to use another pair so the water won't escape when I'm changing them from pos. 2 to pos.1 )

If this works maybe I can convince my family to let me do the first one!

Do you think it will work?

Cool - take photos as you do it and then post an Instructable.

I've got an exam tomorrow. After that I'll start buying materials. The hardest part is probably finding a good motor...

. Bite my gun-toting, American butt! friggin' Limeys and all those extra u's <snicker>

. A dishwasher pump should work. They provide a decent amount of pressure and flow and are designed to handle foreign matter.

I'm going to test a dishwasher pump. If it works it'll spare me a great amount of work, but I doub't it has the necessary flow.

. Without the restriction of the nozzles on the spraybar, you should get quite a bit of flow. Whether it will be enough ... I'm not sure, but would be willing to bet a nickle it will be. . How about a washing machine pump? Auto engine water pump?

To be honest, I think "pool water filtering" and "major waste removal" need to be two different operations; with the removal of large waste like leaves, etc. "vacuumed" out on a weekly basis.
This will prevent one from needing to replace the filter every few days or maybe even hours.

Here, at this link, guidelines on the process are given. Of course, that requires a separate pump and the device that is drawn over the bottom to pickup the debris.

Other then the problem of the filters becoming clogged frequently, it is also very hard to move the volume of water needed to "clean" the sediment at the bottom of the pool, given the amount of water involved.

I am sorry that this post presents more problems then solutions....

Well I just really want to remove the grass and bugs that fall in the pool (it's not pleasant to swim with bugs around you :) ) and for that I think it'll be enough to do as I thought.

you can hook the pool vac to a "motorpump" that is strong and force debris thru it it will destroy the smaller fibers and you will then have to filter the bigger particles but it will be enough

Thanks for the drawing! It's great! The only problem is that the pump must be underwater and it is old so I'm affraid to get shocked if i'm in the water with the pump in. After I posted this topic I thought of a solution that I think will work, but I must get my family's consent for that: We have to repaint the pool so I thought of opening a hole in the ground next to the pool where I'd place a plastic box. Then I'd drill 2 holes in the pool's wall and connect the pool with the box (and solved the problem of having to 'lift' the water) then I'd make a simple sistem to make the water flow and attach it to a filter. Of course, in one of the holes in the pool there'd be a hose... I'll post a comment with the sketch of my diy water pump/acelerator so you can give me your opinion

How about this? Use the pump to draw water into a tank, barrel etc, through a filter and back into the pool. Spray the water back onto the surface to cut down on turbulence that would disturb the stuff you are trying to suck up. If the inlet and outlet of the tank are both at the top, and the filter is vertical between, the filter (mesh) should take longer to clog, as some of the stuff will settle before it reaches the filter.
