Hello all. I’ve struggled with backflow into my manual pump Jabsco head for several years. Replacing the joker valve works OK for awhile but I’d like to make it a little better. Last weekend coming back home from 4 days out with a tank maybe 3/4 full, we ran into a bit of a blow and sailed for an hour or so on port tack at 20° + heel. we ended up with several inches of very smelly tank contents in the shower bilge. The top of my tank is about 12” above the head discharge. The discharge line has a direct routing with no overboard y-valves and no loops. Problem is that it empties into the tank on the starboard side wall so on a port tack, the discharge hose is exposed to the full brunt of the tank. My first thought was to put a loop in the line but I can only get it about 4” higher than the tank without significant cabinet surgery. Reading lots of these forum posts, Peggy has convinced me I do not need a vented loop and may not need a loop at all, the real solution is to move the tank inlet to the other side so it’s close to the boat centerline.
Which brings me to my question. It seems I have 2 options to move the discharge interface. The obvious one is to plug the existing port and make a new one on the top (I have no room on the port side) using one of those spiffy Uniseal fitting and a 90° elbow. But wouldn’t it be simpler to just use the existing hole,remove the fitting, upsize it for a Uniseal fitting then install a section of rigid 1.5” pvc pipe into the tank with its end inside the tank near the far wall (near boat centerline)? This Puts the real discharge location where I want it but it seems to easy so I must be missing something. Thoughts and advice please.
Thanks!
