You're a very brave man. Considering the very high pressure the macerator pump puts on the smaller hose there is a very real possibility it could burst - I don't have the nerve to walk away from mine for even a minute!!
Yuck! The Sewer Solution I use isn't actually a macerator..rather it merely uses water-jet power to liquify the..um...tank contents as they drain past the water jet. Not a whole lot of pressure actually. And, the hose is thick stuff...super thick walled. Hose is stainless hose clamped at both ends and after the 10 foot hose, it's all 1 inch pvc from there to the drain. Again, not a ton of pressure, but it's effective. My current run is 40 feet and slightly uphill.
Go figure. Who designs these lots?
