Auto Water Change ideas???

[Doo]

This is all very cool!

Does anyone have any pictures or sketches?

where do you get these valves or solenoids from?

I am going to post what I imagine but don't know where to get the parts from...

Where is the salt coming from? so far I see drain then water topped off with fresh water, I'm assuming that's what you mean by the auto top off.

www.fishbowl-innovations.com has solenoids, As well as a couple on ebay. Search ebay user valves4projects I think he's still got all plastic solenoids

I'm not sure how any solenoid valves will hold up in saltwater, but for fresh water top off you can use Rainbird sprinkler valves which run on 24VAC so you'll need an adapter. These valves come with a 5 year warranty and are guaranteed to fail in the off position. They also don't leak at low pressure like some other types are suppose to. Been using them for years with no problems and the only part you'll ever have to replace is the solenoid itself which is easy to get and replace. I never liked the look of those smaller solenoid valves made for the hobby, I'd rather use a well known proven product.

There's lots of all plastic valves working in industry, with alot worse substances than SW. There is a few classes of material's. But on average, they will be just fine with SW applications.

Hello,

This float switch looks nice with the John Guest fitting already pre-installed. Are you using them or have you used them before? Considering of order two to do auto water change (one to drain water, one to let water come in) with one of the basic controllers from Digital Aquatics for my brother's turtle tank.

I'm using a couple identical as those for my auto top off and have been in service for over 4 yrs with no problems and they are exposed to a salty environment. They get fairly warm when they are cycled on so you have to watch where you mount them.

I am not mixing the salt at the time of the water change!

I am going to have it pre-mixed. Auto top off is the system I am going to be using...
