I have a 2007 2551 that I am reconditioning. I had leaks in the valves of both the gray and black water. I fixed them both by replacing the gaskets and adjusting the electric valve screws.
That process gave me a chance to understand the Sani Con macerator system and I hope improve on what I have. In that process I replaced some hoses and found that Menards had exactly what I needed. I used clear plastic and spa hoses that both had the correct ID to fit the Sani Con system. And I also found that the Valterra SS01 RV Sewer Solution Drainage Kit with 10' Hose and Accessories fits the Sani Con system that I have. (I'm not sure about the newer PCs). I'm not using the Valterra power jet or the quick disconnect but using the hose and elbow adapter still makes the Valterra replacement hose less expensive then purchasing the Sani Con hose replacement.
The 10' Valterra length is all I need for most situations. I'm using the old Sani Com hose as a backup or extension with a removable fitting between the Sani Con and Vanterra hoses.
I'm using a 3' Spa hose by connecting it to the last fitting from the macerator, adding another 90 elbow and running it into the PC hose storage box. With a fitting I'm connecting the Spa hose to the Valterra hose. I also used two 90 degree fittings from the macerator to inside the hose storage box. That eliminated the hose pinching the flow from the macerator because of the sharp bend required from the macerator to the hole into the hose storage area.
I tested everything and the macerator preformed flawlessly and with better pressure with the Valterra hose and modifications.
