Guys, I need some quick help.
I have the CPR Overflow box CS50 - 300gph. I have it hooked up to a tank in my kitchen for experimentation. I have a few issues though.
1. I wasn't able to find a PVC fitting for the bulkhead that is draining the overflow box. It's 3/4 inch diameter but the threads are tighter than anything I was able to find at Menards or Home depot. I ended up buying a few feet of 1/2 inch vinyl tubing that 'sort of' fits into the inner diameter of the bulkhead. This worked for experimentation only. Even if I were to silicone it in to the inside of the bulkhead I just wouldn't feel safe using it long term. I also couldn't find any tubing large enough to fit over the 3/4 inch bulkhead. The largest they had was 1 1/2 inch tubing but at that diameter it's so thick you can't force it over the threads. What do you guys use?
2. When using the Overflow box, I had the aqualifter (air pump) hooked up as well. It kept sucking water into the air line and pumping it out the outflow... I assume once the siphon is started all I need is to keep it air tight... do I just turn the air pump on until the siphon starts and the unplug the air pump?
