Backflow again

[Al]

We have had a backflow problem too (many posts on this topic) and decided to replace the pump assembly all at one time so we could rebuild the other one and have a spare. So far, no return of the backflow. I am waiting to see if the backflow comes back in a few days like you mention with other problems (vent, etc.) So, now I have on hand the old pump assembly and a spare repair kit. I want to clean the old assembly before installing the parts. Can you recommend a cleaning product? I thought of soaking it in a bucket first to clean it because I would rather not wear rubber gloves while repairing the assembly.

Just pump plenty of clean of water and detergent

through it. Put a piece of intake hose on it...stick the end of the hose a bucket of water and detergent and pump it through. If there isn't a tube of teflon grease in the rebuild kit, be sure to buy one and use it when you rebuild. Seems to me it would have made more sense just to try replacing the joker valve ($8) instead of spending $150-$175 for a new pump and rebuild kit that include new joker valves. Swapping out pumps every time you have backflow is a very expensive approach--especially to a problem that has nothing to do with the pump, but is downstream of the toilet...IF, in fact the problem IS backflow, and not intake water due to a failed wet/dry valve (a part that isn't in the rebuld kit). The only part in the new toilet that's blocked the backflow is the joker valve, which is in the head discharge fitting. Depending on how much you use your boat, my guess is, you'll start to see a little water in the bowl again along about December/January.I don't think it makes any sense to rebuild the old pump. Keep the kit to use as spares for the new one.
