Tomorrow I will tackle a problem that has plagued me forever. I finally did some drain isolation tests to see what was flowing into the black tank, and what was flowing into the grey tank. No real surprises here, except that it led to the realization that the black tank has no vent, only the grey tank is vented! That explains some of the odor problems I have been having. I have developed a strategy to overcome this issue with minimum impact by adding a vent pipe from the grey tank to the black tank. This will allow the single vent to serve both tanks. This is a relatively easy fix, since the tanks are side by side, and easily accessed. No structural mods required. I am also adding a ‘wind venturi’ to the roof vent to assist purging the tanks.

While at the RV store this week picking up a few repair parts, I managed to pick up a new tank level monitor system for a pittance of $25. I found it, dirty but in the original unopened box almost hidden on a shelf, marked at $55. I asked the service manager, Gene, if that was the best price, and he reduced it to $25. This unit usually sells at an inflated price of $150 or so. I spent most of today installing the “tank end” of the system. Not a fun job, but do-able, after 3 time-killing trips to town to get parts costing about $5 each trip. The gas cost more than the parts. I will do the topside portion sometime later, maybe even on the road. One might ask why bother, sine I already have level semsors. The new sensors are external electronic type that do not become unreliable due to contamination.

OK, spring is approaching. The weather for the last couple of weeks here at Sierra Vista, AZ, have been so nice it is hard to believe that one must wait a little longer to depart.

Just as well, as I have embarked on some repairs/updates to Barth. I have scheduled a mobile repair service to reseal suspect areas of the roof. I think there may be some unseen seepage around vents, antennas, lights, skylights, satellite dish, etc. It has been years since any attention was given to this periodic necessity. I could do it myself, however, I do not do roofs, period!
