Hi,

We are moving on to our little boat this weekend. We have a few jobs left to do, but I have an awkward concern. We have a standard Jabsco from the 90s and a brand new pump assembly, but it's not nearly as forceful as something from a house.

If sometimes my home toilet clogs up from going, what hope do I have with a Jabsco? How do others make the solid stuff go down? The jabsco goes directly out or to a tank for pumpout. We don't have any electrical stuff or macerator pump.

Firstly, congratulations on your digestive system's robustness. Like Shrek said so long ago, "Better out than in, eh?"

Secondly, don't be so shy. If you find blockage to be a frequent problem (the head's not yours), get some cheap plastic spatulas and be your own macerator. It'll go down sooner or later.

Rinse 'em off best you can and store 'em in a ziploc until proper cleaning can be arranged.

Be creative!

In 9 years, 3 of these full time on boat, of having a basic manual Jansco head it never clogged. If it does fill with water till it softens enough to pump it clear.

This of course only applies it is is waste and non clumping tp

Maybe you just need more Fibre in your diet!

Seriously though, there is a reason the Jabsco has been around and unchanged for so many years...it just works! A residential toilet relies purely on gravity and water volume to flush, the Jabsco is a positive displacement pump. It will flush just fine, some loads just take a bit more water. It helps if you make sure there is some water in the bowl before you start, then it doesn't stick as much.

I'm only guessing the home toilet clogs, due to the amount of paper used. That must be used sparingly on a boat head. Less so, if you have a mascerating electric head. Some even bag their toilet paper, rather than flush, but I just can't get my head around it.

Another serious issue with marine heads is flushing enough water. With fairly small holding tanks, many try to conserve space. However, if you don't pump enough clear water to chase the waste all the way to the tank, it will settle back down the piping, at the base of your head, where the joker valve lives. Once it gets all caked around the valve, it won't open for the next flush.

Buy Peggy Halls book, How to get rid of Boat odors. Lots of good advice on the proper design and usage of marine heads.

My thoughts also. Some people like to use a giant clump of toiled paper. On a boat, you need to use only what you need to use. That doesn't mean that you try to get by with just one square every time, but you should think about how much you really need to keep your hands out of it, and get the job done.

My wife and I go through a roll in 7-8 days. We never want for toilet paper. We use as much as we need, but no more. We've never had a clogging problem, either at home or on the boat. We do use 2-ply paper, about 250 squares per roll.

Maybe that's too much information, but on a boat, it does become an important issue. Nobody -- and I mean NOBODY! -- considers unclogging a head as time pleasantly spent!

I wish too much TP was the issue. We ha e discussed how much and what kind to use, so I think we will be ok on that front. I just need to get our engine online before we will up the tank so we can pump out. Luckily the pump is very close.

Anyone try to move a 29ft boat with a tiny minikota trolling motor to get to a pump out ? :->

I was able to move my 30 footer quite easily with my rib and 4hp tied alongside.

My advise to guests, who are sometimes concerned about making a clog, is that they can always flush at the mid point, before using the TP. I won't complain.

Also, unless someone flushed a forbiden item (flushable wipes, facial tissue, personal products), it will alsmost always soften up and then pass in a few minutes. Fresh TP can cause a blockage, but with the addition of some water and time, if it is dissolving tissue, it dissolves. Use only TP that falls apart in water.

Not often for me either (only extreme non-flashables).

One more thing. I added an inline intake strain after clogging on seagrass. Some marinas here have a lot of it, and it can clog the intake side head, as well as get smelly from rotting grass in the rim of the bowl. Rare problem, but this fixed it.

There are several models of bolt on bidets available. I found that the consumption of tp is greatly reduced. and are all together beneficial. Have them on all my toilets. R and D was done by bears in the woods so you know it's true. Vindiloo.

We did get a bidet for our house to test it before we moved, but I never installed it. Maybe it will work on the boat if I plumb some pressurized water. I'll see if I can measure to see if it will fit.

Further to this scintillating conversation ,I thought I should mention that most bidets have a gender designated control with a weak detent for the off position. Unlike a house toilet a marine head can fill to overflow if drippt at overnight. Trust no-one. So it's 3 in the morning and that damm jabsco pump is on again sort of thing.
