My system is nearly complete. I really learned some leassons in plumbing. Now all I need to do is to put together a top off system together. What would you recommend as the best auto top that won't break the bank?
So how does that work. Say the one that goes into the sump. Does the one switch turn a pump in a tank somewhere on, which puts water from that resevoir into the sump until it reaches a certain level then the second one shuts the pump of????? How does the single switch work, just off and on alot???? For a guy who has to haul water everyday, this is intrigueing, especially for weekends when I want to leave town, I always have to find someone to water the fish.
The Double Switch works as If the level go too low it would kick on the pump and top off the system... If for Some reason lets say the bottom switch gor stuck and the water kept filling the Top one would shut off the pump as to not flood the tank so bad... one works on low water the other works on high water... Just an Added Safety percaution... With that setup all you need to provide is the top off pump...
My recommendation is get a float valve like the ones Kent sales, connect it to the makeup bucket, tank, whatever, and let gravity do the work. Only thing you have to do is make sure if the float failed, the sump would hold all the makeup water without overflowing.
Go to floatswitch.com (sp) buy a float switch then pickup an aqua lifter pump. Open up the aqualifter and wire up the switch.
The Whole thing including pump and hoses should cost you less than $25. This is very reliable and will not break the bank. Mine has run flawlessly for 6 months.
