Does anyone have any experience with a 1" lay flat hose for their macerator discharge? I'm thinking about making 2 25' sections. Txs

This is what I'm referring to.

You mean like this?

Yep. No problem. I have a 25ft 1in id flat hose that I adapted a full bore (this is key) brass female garden hose to one end and a heavy 1" galvanized elbow with a short nipple to keep the other end weighted in the dump. Just make sure to extend the flat all the way with no kinks or turns and it pops right open and flows without loading the sani-con pump at all.

If you are connecting 2 25ft flats I'd join the flats with a full 1in connector (use a 1 in threaded union), not a garden hose connector. Flow resistance minimization is the key for pumping this length and there is certainly enough resistance in just "inflating" the flat hose.

Main reason for the flat is that it stores much better than a 3/4 garden hose and it probably flows better as well.

Beware, the blue plastic seems to like to eat the white plastic floor in my water bay. If you store the blue flat hose on plastic use a cheap plastic place-mat under it.

The garden hose end uses an non-swivel female garden (this has the largest flow) - 3/4 npt screwed into a 3/4 npt - 1 npt adapter and the 1 npt screws into the 1 npt to 1 nipple which slips into the flat. My flat came with the 1 npt/1 nipple already installed on both ends. That was really nice and something to look for. I think I got mine at a Tractor Supply - not all stores carry the smaller flats.

Good luck!

Yep thats what I needed to know. I plan on mounting my pump in the bottom of a 5 gal bucket and storing the hoses, etc above it. What is the diameter of your coiled hose? I'm sure it will fit in the bucket. As far as connecting 2 hoses I was thinking of PVC fittings. Do it Best carries 100' 1&1/2" for under $50 shipped to store and I can cut to length. I'm just not sure if all blue flat hoses are the same PSI etc.

My coil is about 8-10 inches - 5 gal bucket fit no problem. There is really no PSI loading so that spec won't matter. A nylon interconnect is fine, just keep it at the 1in NPT coupler size. I used the galvanized fittings to get the weight to keep that end in the dump. You can use the grey 1in plastic fittings to convert the flat to NPT as those will have the nipple end needed to go in the flat. You might want to cut down that nipple as you won't need the typically 2 odd inch nipples those gray plastics come with. Only an inch will do fine and allow tighter coiling. Nylon garden hose adapters are probably not full flow - I'd stay brass for that and use nylon to adapt the brass from 3/4 npt to 1npt to attach to the nipple fittings.
