We still have a little afraid when you buy this type of equipment, even the DIY enthusiast does not like the idea of having to troubleshoot this kind of device; I see this unit from 2 three months now it works very well, it it is a small startup problem; and yes I had to put their hands in the dough so to speak; for obvious reasons of lack of space and fear of leakage, I introduced the flexible discharge toilet too close to the entrance of the mill or even 2 mm inside, which was a problem at one time , disposal of waste deposited on the pump center prevented a proper waste disposal, since the problem is solved so good (for 1 1/2 months more). Just a little thing, pipes greenhouses seen in the offer were not provided in the command
