Backyard Aquaponics
A place to discuss aquaponics

Hey Guys,

I've got a 2200lt tank above my AP system, I plan to use it to auto top up my system when it gets below a minimum level (gravity fed). I plan to bury some poly pipe from the tank to my pond so it's hidden, the problem I've got is what to put on the end?

I'm hoping for something that is relatively hidden. My pond drops about 8 inches when the growbeds are full (and overflowing through the stand pipe), I would like it so that if it gets any lower than this, it's topped up to the minimum level. Does anyone have any suggestions? I'm hoping for something enclosed in a tube, a vertical cylinder if you will, with a poly barb on top, sort of a plug and play device I've got a design in my head, something I could whack together, but if something exists, no point reinventing the wheel

Cheers!

Old toilet cistern, can even fine tune the fill height, must be a heap around with people converting to dual flush.

P.S. may have some Sunday (the buggers been at trade school in melb )

+1 Its what I will be using, $30 or so from bunnings

Yep - I intend to do the same thing :-)

But like, isn't that like... ugly

Try telling Kenny that

Haven't you got a nanna, just put a doily over it, or maybe a tea pot cosy (fish safe of course)

well... true I'll have a look at the local irrigation shop on the way home I'll report back if I find anything suitably sexy!

OK! Well I found what I'm looking for, this is the design I had in my head Now just got to get one here! If any one's interested we could do a joint order

No lever arm
No exterior moving parts
Resistant to freezing
Indestructible
Installs in seconds
No float ball
High volume
Anti-siphon
Rust-proof

Ill have one at that price

is that... good?



OK! I was wondering where you were going with your first post

Hopefully they work without pressure (or low pressure)? As I will be gravity feeding it, I hope it just opens when the water level falls below where you place it.

sort of......while there is no exterior moving parts-

• The valve needs to be cleaned periodically depending on the cleanliness of the water source.
• Wash the valve and valve parts with fresh water. Dirt, rust, sediment and sand can build up on the valve and cause it to malfunction.
• The valve has two very important holes that run through the center of it. If either of these holes becomes clogged, the valve will not shut off.



A standard float valve does not have these problems.

OK, well the water I'll be feeding it is from my tank, not the AP system So it's crystal clear and gunk free. I thought that too then slapped myself in the forehead when I actually though about what I'm using it for... I was like, hmm, but the waters full of... wait a second *slap*



Seems like the 1/2" version will work at 0lbs of pressure! You win again gravity! (The 1" requires 8lb, so no good for gravity fed.)
