Gravity Feed

[Nilz]

Ok im getting a 4inch bottom drain and i know it has to be gravity feed but i really dont understand what that means... Like do i have to get a vortex filter and does this have to be buried the same level as the bottom drain? if it does where does the piping go from the vortex filter? and is there another way of gravity feeding it without having to bury the filter? is there a out of ground gravity feed system?

Re: so confused

Some one that knows will help you nilz, I don't use that type of set up so can't help.

Take a look at this site the have some good information.

I just put black abs pipe in my pond ,with shower type covering on it and put a pump up in the filter box and turn it on when I see muck on the bottom building up went as simple as I could because I did not want to cut the liner .the shower drain can be turned up or turned down by just turning the pipe .I want to add an airline to it but trying to see how to add it

It doesn't have to be as deep as the drain just lower than water level. For true gravity feed it is either you need a lower settlement or you raise your pond up.

ok so like if i get a vortex filter it just needs to be lower then the water level in the pond? and the water will just go to it?

You want the top of vortex an inch or two higher but the water level will be the same. The water in the pond and filter will be at the same height because they are joined bodies of water and they naturally do that.

when doing the gravity fed system means if your filter are open tops the waterline in them are set about 1 to 2 inches below the top of the filters when the pond is full.
This way the pumps are after the filtration. Closed pressurized system filters need the pump before them.
On a closed pressurized system filter you would go from BD to mechcanicl filter to pump then to the pressurized filter.(bead filter)

 

[Nilz]

ok the the mechanical filter would be the vortex filter? it would go BD>Vortex>Pump>Beadfilter?

 

[DoDad]

yes

This may help, look at figure 4a

this is just what i was looking for thanks!

The cetus has a max rate of 4755 gallons per hour. If you had one on each bottom drain your turnover rate would be 9520 per hour.
