I'm looking a possibly getting a killer deal on 150 ft of industrial grade collapsable hose problem is all the macerating pumps I can find have a outlet of 1 in & the hose is 1 1/2 in, what would be negative effect of stepping up to 1 1/2 in from 1 in off the outlet of a macerating pump.

Another option is to go with one gray tank and a composting toilet. More flexibility that way. My plan os for one 110gl gray tank and forgo the black tank altogethor. Saves a lot of plumbing.

You're talking about discharge hose that lays flat when not in use, right? You should have bought it!

I have 20 feet of 1" flat discharge host for my macerator and it isn't big enough (diameter). It fits the discharge port, which is nice, but the trouble starts there. The pump wants to discharge so much that it makes the hose stand out straight. Because the hose doesn't have any form on its own it doesn't bend very well; the walls tend to collapse or pinch. The macerator is so eager to move a lot of volume that when it hits that slight restriction, the upstream hose inflates like a balloon and turns the pinch into a kink, making the problem even worse. It takes some doing once the pump is running to straighten the kinks enough to get some flow.

I like the flat discharge hose concept, but I haven't put enough thought into figuring out how to make it work. I'd like to use a short section, maybe 5-7 feet, for most dump needs and have a coupler so that it can be extended to 20-30 feet for special occasions. Maybe a chicago-style coupler like those used on large compressed air lines..? I'd love to hear your ideas about it.

Haven't gotten our waste tanks yet. Original plan was to have black/grey combo (1 tank). But I like what I've been reading.

If I was to go with 2 what would be the recommendation for sizes for black & for grey. Our water tank is 28 gal and all I know is that I want my waste to be slightly more so that I run out of water before I run out of room for waste.

We have a Jabsco crapper (marine crapper) and can limit the amount of water we use there. I've had thoughts of putting a mascerator in line and what I'm reading I can flip a switch and add grey water when I need or want to.

With our equipment would 5-10 gal for black waste be too small and maybe 20 gal for grey water? Or should we be staying with the black/grey combo

Hubby is installing crapper over drivers side wheel well and to put a tank right there in ront of the tires would be a little tricky cause I think the muffler is coming out right there.

I would really try to put your toilet right above the black tank, nice straight drop, no bends or twists to have a clog. also easier to install.
