Wow.. I just tested it out today..

My results are great.

I hooked up the outlet of the 120GPH pump to the inlet of the 360GPH pump through 1/2" tubing.. 1ft long.

My test was a great success.

I turned on the 360GPH pump and it had enough suction to pull water through the smaller pumps inlet.. and the 360GPH pump had enough power to put out the same head as normal!

I then had the 120GPH pump push water through the 360GPH pump with the 360GPH pump off..

BAM! Worked great! Water spewed out of the outlet of the 360GPH pump and the 120GPH pump was able to keep the same head pressure.

I then turned on both pumps.. I stood up on a bench .. with a long piece of tubing (atleast 10ft)

I turned on the 360GPH pump.. Good.. I got my 6ft of head pressure like normal.. it was still set up.. sucking water through the smaller 120GPH pump.. then I turned on the 120GPH pump and the 360GPH pump .. damn! The head WENT WAY UP! I had to turn the pumps off because the water rushed up the tubing way fast! The head on the 120GPH pump is like 3ft or less.. Combinded with the 360GPH pump it was incredible.. a head pressure higher then 10ft!

All I know is that the water rushed to the top of the 1/2" tubing... and would of kept going if I had more tubing.. I am guessing a head of atleast 13Ft!

This proves pump redundency as well.. if one pump should fail.. the other will still have enough power to circulate water through my system. This also proves that I only need 1 pump on at a time.. say if silence is needed.. or I go to bed.. PC is left on and idling.. or.. if I turn off my PC.. I am going to keep the compressor on.. using the thermostat and turning the compressor down to like 1 or 2 power setting.. this way I can just turn my PC on then with out having to wait for the compressor to start chilling the water.

So I will leave the 120GPH pump on circulating the water so it doesn't ice up or anything anywhere.. Even though I am going to have anti-freeze in the system.. still good to keep the water flowing because it's less traumatic on the pumps to start flowing this freezing water around.

When I just had the 360GPH pump with no tubing on it.. just squirting water straight out of it's outlet.. and then turned on the 120GPH pump.. there wasn't much gain in the water height..

The only problem is that when I have both pumps on.. I hear a ticking sound in the 120GPH pump.. not sure what this is.. I hope it's nothing damaging to the pump.
