Carl- when I did my macerator i was picky. I wanted a 1" id hose. That was smoothwall on the id. And flexible at a wide range if temps. After going to every big box home inprovement, plumbing, hardware and industrial supply shop in a 100 mile radious I could not find something I was happy with. Talking to Jim K he said he was able to find such a hose so I bought from him and was not disappointed.

I did notice there might be a simmilar hose at the overton store. But had no reason to look at it closer when I was there a month ago.

I was running mt macerator when it was just above freezing and hose is pliable.

Not that kit at all.

Just the hose he supplies with his macerator kit. I only bought the hose only:

I also use heavy duty 3/4" garden hose. I bought a 50' at Home Depot. I cut it in half and fastened the cut end to the macerator through a 3/4" to 1/2" adapter. Don't let the Home Depot plumbing dept tell you they don't have the adapter. It's not in Plumbing. You'll find it in the lawn sprinkler area.
Attach the end with the male hose end. Then you can use a hose cap on it to prevent the sewage from flowing out. I store the other 25' section in my propane compartment and attach the hose connectors together when I need to reach farther. Once I had to go about 150 feet to a sewer clean out while traveling. So I bought a cheap 5/8 50' vinyl hose and used that. The macerator ran fine while pumping through the 5/8 hose. I ran a 20ft piece of 1-1/4" pvc alongside my frame. The front rested atop the diagonal brace at the front and tied with a stainless spiral clamp just below the rear cross frame at the back. I also used the same clamps along the side frame. East to slide out the hose, unscrew the cap and pump out. Then put the clamp back on and slide it back into the storage pipe. No need to flush a hose.
You can find the one piece 20' pipe at a plumbing supply company. Get one with a bell end (made for connecting another pipe without using a fitting). This makes it easier to feed the hose in the end.
