Today's addition is a self designed 4 chamber sump pump. Did this because system came stock with a 12x12x58 Sump tank which effectively ate all of the cabinet space. Although it was a 40 gal tank,given the height of the partitions, only held ~30 gal. I went with a 39 high with 4 chambers and built some shelves on one sidenext to the sump tank. Amazing how fast stuff accumulates. Doors still off (had to pull to insert tank and install shelves) till I go live. System ran for about 2 weeks once completed. So of course I decided I did not like my blue film background on the DT so pulled it all apart to replace that with a LED system, as yet to be designed. In the last 3 years I have lost the ability to lift this tank with 2 people so have to construct a rolling table of some sort to slide the tank off of the stand to reach the rear panel. Typical, 2 steps forward, 1.99 back. As an aside since I have kinda bashed the company. The tank operation is almost silent. The spiral insert they use on the single drain is actually silent. In addition the pump is also very quiet.
