    I want to secure a couple of floats in a 'sump', one for low water and one for high water. I've seen the PVC caps and strainer idea; any other thoughts? Something that was adjustable would be nice.

    Can't Remember Where, Though...

    Hi,

    Somewhere along the way, I saw a set up for marine aquariums that looked to be a post clamped to the sump and the float attached (clamped, I think) at whatever level you needed.

    The set up reminded me of the older style floats in toilet tanks.

    Are you after a float switch type to maybe control a pump, or a float valve type no elec. :D

    Does this post help from someone who has done a diy top up system?

    Yeah, I'm looking for an electronic float, similar to the setup in the green garbage can. I plan a similar system, with a bilge pump to drain water and a solenoid to top up the sump.

    I was thinking about using a pipe with some Tees riding the pipe. I would move the Tees up/down the pipe as required. The floats would be attached to the free leg of the Tee. Although physically attaching the Tees (same size pipe/Tee) does offer the benefit of a conduit for the wires as this guy did.

    Thanks for the ideas.

    Odd thought. What about using the pump without a solenoid? Put in a T fitting up near the top of your loop and leave it open to the air. As long as you don't blast water out of the top of the T ( which you could extend with a pipe ) you should be fine. Once the pump shuts off the open end will break any siphon. This avoids the need for a solenoid at all.

    Hmmm, I was rambling I see...

    Pump out is to drain sludge/water from the bottom of my sump/settlement chamber. The filter return to the aquarium will suck the water off the top-ish of the sump.

    Solenoid is on the water line refilling the sump, not on the pump draining the sump.

    Clear as Detritus? ;)
