Has anyone tried a normal household macerating toilet in a conversion? Seems like it would allow locating the toilet anywhere and make draining the black tank easy. | ||

Bazz, no direct experience but I've looked at a lot of different plumbing items. If it's labeled "household", it usually means "lots of water used" and (for something like mascerating), I'd expect high current use. I hope that there's something out there that's an exception to this, but so far ... | ||

There are macerating boat toilets that pump waste where you need it. A manual boat toilet will push waste a long distance , no need for a macerator. The problem is the std drop down RV toilet is by far the least maint and lowest water use. If you don't want to crawl up hills with a TON of water ,water use and capture is a BIG consideration.

Morning Basil, On a humorous note, you have to watch advice from Bruce, as he called our buses "Murrikins." Now that we have stopped laughing, here's my thoughts. As you say, a macerator would make emptying black tanks easier, and would resolve the design problem of having to locate the toilet over a bay. The disadvantages that I see are slightly more water use, maybe, and the necessity for an inverter to flush while off shore. Now, unlike the highly touted all-electric toilet that was posted a couple of weeks ago, your idea would only use 'high' current for seconds, unlike the other which uses it for fifteen minutes. So, I say welcome, try it, and a big thank you for asking, instead of making a big post on how great your stuff is, and then calling people names who disagree with you! George | ||

Thanks for the input. A little more detail....I have an eagle with an 84" ceiling. I'd like to raise the floor of part of the bus by 7 inches, which will allow me to place four 6" high waste tanks (104x17, 35G) under the floor. The toilet does go over one tank so I could drop directly. However, I figured if I macerate the waste before it goes in, I could connect all four to give me 140G of waste capacity. I do recognize I now need an inverter or shore line to flush, and water use will rise. This Sanistar toilet says it uses 1.1 gallons per flush. How would that compare to realistic water use in an RV toilet when cleanout and multiple flushes are included? I am also thinking about using their gray water pump for the shower. Has anyone had any experience with pumping shower water? | ||

This Sanistar toilet says it uses 1.1 gallons per flush A drop RV toilet is 1/2 pint for a pee, and an entire PINT! for an ALGORE. RV stuff works , why re-engineer 50 or 60 years of success? FF | ||

FF, you're right about the water usage. I also noted that they're $700-750, and power usage is 600 - 950 watts (although, as GT says, it's a short-time power draw). They *will* pump "uphill" (if it were critical for you to have that feature) and pump out your shower (if it were critical for you to have that feature) -- and if you're "power-poling" all the time, maybe the water/power issue wouldn't be an issue. But, as FF says, things built for RV's are *good* and it's probably not a good thing to ignore them unless you have a good reason to "do it your way". | ||

ON our coach we did not wish to have any tanks in the bays for freezing hassles. WE chose a 55g flat tank that is (IF i REMEMBER ) 10 or 11 inches high. A low profile Sealand RV toilet was bolted to the top of the tank (after it was boxed and top suitably reinforced ). Works just fine as the rest of tank surface is under the sink in the galley. ON the opposite side we put the FW tank , and its built under a long series of drawer storage, where the bottom foot is not missed. As the tank would be a bunch of hours to pull, the Dupree waste dump valve was a better install than a cheaper RV unit. To dump we go outside , open a small door, connect the hose and go inside and pull the dump valve handle.Nothing to worry about in freezing weather. FF | ||

We have a marine masserater toilet. It is a 12 volt starter motor that does the dirty deed. It uses very little power and no more water than our old gravity drop r/v style that was in previous campers. We control how much water goes into the bowl just like in previous campers. We have a rear bath and it pumps it to the plumbing bay no problem. Nice ones are kinda pricy 6 to 7 hundred. | ||

FF, in my configuration the toilet would be over the same area the dump valve is, i.e. the bottom of the slope. My concern was that material would 'pile up' making the rest of the tank less useful. The tank I am looking at is 6" high, 104" long and 17" wide. I was thinking about putting four across connected to each other, all under the 7 inch raised floor under the queen bed. Do you have the toilet positioned so material runs away from it in the tank? Is 'piling up' of material a big issue to be concerned about? | ||

Its called accreation , or drop out , when the stuff settles to the tank bottom and begins to collect. No big deal, you simply do what RV folks do when ever a lack of water causes "standing soldiers" firm non flushing piles from too little water in the waste.Usually from operating the system in a campground wrong. Dump 20-30lbs of ICE into a freshly dumped tank and go for a ride . Accelerate and brake with vigor and the tank will be clean with no hassles. You will definiatly have problems with 4 tanks! as they will not get the velocity needed to carry off much of anything. One bigger deeper tank will work far better. Time for Plan B.
