Hey guys. Is there a way to dial in the ammount of water going out from the sump and the new water coming in with the automatic water changer. It seems impossible to get the same water coming in and going out. Anyone have any tricks for doing this? If more is going out or going on in worried tank could overflow
 
Yes, just use gravity. Drill a hole in the side of your sump. As soon as the water level in the sump rises to the level of that hole, it'll drain out of the hole you drilled in the sump.

To adjust the height of that drain hole quickly and easily, put it 3-4 inches below desired sump water level, and put an elbow and short piece of pipe in it. Now you can trim that piece of pipe's length to whatever length you want to put the sump water level where you want--a standpipe.

Is there a reason it has to be at the top of the water level I have mine drilled in the middle of my water level and have s ball valve on it. I was just thinking I could open the ball valve just enough to let water trickle out at the same rate the automatic water changer pumps in. Ball valve is closed now and I am about to hook up the auto water changer so I was wondering how to match them. Now that I already have it drilled this way instead of the better way you mentioned that I didn't think of lol what can I do?
 
Read the second paragraph I posted. On the inside of your sump, you put a elbow with a short piece of PVC sticking up. Water in teh sump has to get above the top of that short peice of pipe to start draining, right? So, you just cut that short piece of pipe to the length needed to make your sump water start draining into the pipe--that's how you set the water level in your sump. Take that ball valve off of there--you'll never get that thing closed the exact right amount to match such a slow trickle of water.
 
If gravity is an option it is almost always the best one.

What I like about Gravity is it works the same way every time it's used. Never breaks. There are no "caveats", no "upgrades", "patches", installation costs for Gravity are zero, it's got a lot going for it.
 
It's terribly reliable. Power goes off and it will still run. Float switches will need a battery back up or else you could see some floods.
 
Yep. Don't ever need to change the batteries on gravity.

ok I see exactly what you mean now it's like a main display overflow but inside the sump. I have it all setup now. My next question is are you guys running the auto water changer straight into your tap water pipe? Or are you filtering it somehow. I am not sure what's in my water but I know my tap water runs through a water softener in my garage. Any filter needed or is it such a small amount of water it will be fine and just get lost in the system?
 
I'm on plain city water, no water softener, chlorine/chloramine treated by the water company. I use a 3 stage chloramine filter I got from the filterguys.biz. I tee off the cold water line under my bathroom sink.

I think Didysis drips without a filter--you have to ask him. But to drip w/o a filter, you have to really trust your water company, have adult stock, know what the chlorine levels in your water supply are--I just filter.

Call filterguys, see what they say. A water softener complicates things a bit.
