Electric Valves Grey & Black water

OH BOY!!! DRAINMASTER! I have three and all have been replaced two to three times under extended warranty then the following winter in Florida the black tank valve failed, drainmaster's B.S. reason was that the good people at Cedar Creek installed them wrong and so did the local Cedar Creek dealer but after some digging I found that CC was NEVER told that those valves could not be positioned horizontally and drainmaster started putting those warning stickers on AFTER CC was having problems, mind you this is "hear say' but I know Cedar Creek would NEVER build such a flaw in any of it's rigs like these junk valves intentionally but I really was surprised that our local Cedar Creek dealer who was paid to do the replacements didn't start asking questions when they see the warning labels on the new valves they repeatedly installed, so much for "idiot-proofing" I guess! So back to the newly failed valve, I'm speaking to a woman at drainmaster who now tells me that the original rocker switches they suppliedshown in this picture turned out to be the problem and the new "mechanical" switchesshown in this picture is the solution so $175 sheckles later and some re-wiring they now work as promised.
These valves have been the only problem I've had with my rig and Cedar Creek sent me replacement manual valves for me to convert and the next failure I will. I asked drainmaster why these switches weren't a recall item as they clearly are the problem but I never got an answer, just a bill.
