Just had a new Jabsco marine head installed on Genesis and just like the one we replaced the bowl will not fill up with raw water. A quick phone call to Jabsco customer service and we found the original installation was not right. Damn $279.00 to replace a perfectly good head.
What is needed was a vented loop at least 12 inches above the holding tank. Sooooo I have to install the tubing and vented look ($32.00).
At least the new macerator and key lock work fine and will get us past the coast guard inspections in the Keys.
