As mentioned elsewhere, this seems a bit clumsy compared to a simple shutoff located between the two drains. I diagrammed my system and concluded the new glycol should be pumped into the innermost drain, while the old glycol comes out of the outermost one. There is only about 1 1/2” of space between the two drains, but I experimented with a pair of needle nose vice grips that seem to squeeze the tubing tight enough to keep the glycols from mixing.Robermcm said:Score! I wrote to Truma Elkhart about the bottom fill glycol replacement process and received the important (and oh so obviously easy) tip on how they do it…..ScottG said:Good morning Rob,
For that double drain, they put a clamp in the top middle in between the two drains. One side is where the new glycol is run in and the other side is where it comes out. It is still a good idea to keep an eye on the reservoir while this process is being done to make sure that there is not a blockage and the reservoir is overflowing.
Hope this helps, have a wonderful day!
