Question:
Hi - we just bought a used camper, it came with a new 3 sewer hose - i believe it is this part number D04-0120PB What do you recommend for the fitting to go into the dump station drain hole? I want to make sure whatever I get will be able to store in a standard sewer hose holder tube. Thanks

Hey John, congrats on the new camper. For a sewer adapter that'll attach to your Quick Drain Sewer Hose item # D04-0120PB, I recommend the EZ Coupler 4-in-1 Adapter item # F02-3103.
The EZ Coupler item # F02-3103 is going to insert directly into your hose for a leak proof connection. It has a 90° elbow so you won't have to worry about aggressively bending your hose. The end that connects to your camp grounds dump station fits 3" slip and 3", 3-1/2", and 4" threaded sewer inlets.
What kind of camper did you get?

Hey John, We have been using EZ thread on couplers for many years and have been very happy with the product. The 90 elbow stays on the hose and stores easily in any sewer hose storage tube. The cone shaped fitting fits in any sewer line drop and the elbow piece fits easily into it and secures in place with a small twist. It is a good idea to place something with a little weight on top of the elbow fitting before pulling release valve. The back pressure may force the connection out of the sewer line drop when the valve is opened.
