2014 Sabre Black Tank Venting into Heat Duct Work !!!
Just upgraded from our Rockwood to a new Sabre 35 QSIK. Love the layout and look of the camper. As with any new camper, there are a bunch of minor issues we are working through and fixing as we go, (shower drain leak, loose items, missing fasteners, etc), and a couple of larger problems we are going to have fixed under warranty at the end of the season. (A/C ducting, fridge fan noise, slide out adjustment, etc.).
That being said, last weekend we developed an awful sewer smell during the night that actually woke the kids up and made them sick. Doing some investigating, the smell is coming from the heat duct work. I pulled the vent covers off and looked in there with a mirror (past the mountains of sawdust!) to find two 3" diameter holes going through the duck work between the kitchen and the bunk room. Underneath the camper, I can't see the hole because there is a large black tank in the way. We do some measuring and find out we can cut the bottom out of one of the cabinets to get access. Apparently Sabre cut holes through the floor and heat duckwork for the black tank vent (luckily this balck tank is only used for the outdoor kitchen sink) before they install the tank. Then they forgot to install the connecting pipe to vent it through the roof, so the tank vents into the duct work! WOW! I'm glad I found this before anyone got really sick or anything blew up!
I'm going to call my dealer as soon as they open, but with camping 3 of the next 4 weekends, I think I'm on my own to come up with a temporary or permanant fix. For now, I taped off the ductwork to keep the fumes out of the camper and the pipe is open venting into the underbelly of the camper.
How many vent pipes stick out the top of a 35 QSIK? I have one sewer loooking vent over the bath, and 2 other unusual ones, one over the master bed room, and one over the bunk room, neither over a wall where a sewer vent would be contained. This camper has four waste tanks. My Rockwood had three tanks and three vents.
Can I cap this tank to seal it up, or does it have to vent?
Thank you for reading to the end of this post, any help would be much appreciated.
