aquasafe canada ro/di waste

[jason604]

hi guys i bought a used aquasafe canada brand ro/di on here and after testing it at home it seem that water was coming out the DI part very very slow.... about 1 drop/ sec.... and i needed to do a water change so i just used the waste water discharge of the unit... is this safe? or very bad? i tested phosphate and the water was at 0.25ppm i didnt change the water of my tank yet. Im still letting the salt mix and the temp even out. I used a milwakee TDS that came with it but each time i put it in saltwater it doesnt show a ppm just 03 in very very tiny font at the top right corner.. tested it with my tap water and it said 7ppm.. what should i do? use the waste water? or how do i fix the unit.. i took off the Di unit connection but the water seem to be coming out super slow from the 4th stage of the unit.
