Backyard Aquaponics
A place to discuss aquaponics

I'm looking at installing a float valve in my 500L ST to ensure the water is topped up from the nearby household water tank.

Any suggestions for a decent unit that would be easy to connect to the garden hose connection of the tank?

..
the best plan is to firstly .. only use a float valve that mounts thru the side or is fully internal.. consistent with the belief that the fewer holes you drill, the less chance of loss or disaster..
Go to AliExpress.com and search for float valves.. ALL soughts of valves on there..

and this might be a good start...

we use these... we have multiple hooked up including two AP systems and the water feeder for my chooks... no metal parts, all plastic!!

Well you can't complain about the price, how long have you had them IceMan?

the first one (chooks water barrel) for over 12 months... the ones in the Aquaponics have only just gone in

Thanks for that; I like cheap and simple.

I've been using red ones from farmer little on eBay for a year. Even ok in duck tank in full sun. Work with low head, even 20cm is enough. Only downside is that they are not adjustable.

I got one from a local fodder store.

Was pretty cheap, and seems to do the job.
