No none. But there are a lot of folks on this forum that say those responders are very inaccurate at best. Mine have never worked correctly not even out of the crate. So when the sink backs up I know the grey water is full and when the black water is slow to flush I know the black water is full. Its never been inaccurate when I test it that way. LOL.
Up until this trip, the accuracy has been excellent. I found that during installation the placement and size of the senders was critical. I taped the senders onto the tank and ran several fill/dump cycles until the numbers were very accurate. Unfortunately, if the system was installed by a dealer, they probably just slapped the sender on the tank where ever it was convenient. You have to consider high side and low side of the tank and find the best compromise location.
