Thor Ace has both macerator and gravity dump. Look for valves in the wet bay that direct flow to one or the other. Close the valve to the outlet you are not using. Some setups have both connected - gravity works by default, macerator works when pump is on.
Low water pressure with 40 PSI at regulator indicates restriction downstream. Check inline water filter, city water check valve, and any winterization valves. Pump running on city water confirms restriction.
Top Presto-Fit alternatives: Camco RhinoFLEX (best value), Valterra Dominator (heavy duty), Lippert Waste Master (premium cam-lock). Look for 20+ mil thickness, quality fittings, and cold-weather flexibility. Avoid ultra-cheap thin-wall hoses.
The Camco Rhino Sewer Hose Adapter Pro is a versatile solution that connects to both threaded and non-threaded RV sewer outlets using a secure clamp system. It eliminates the need for multiple adapters and provides a reliable, leak-resistant connection for most RV waste systems.
Tight sewer connections from oversized flanges. Apply silicone lubricant, lightly sand the bayonet ears with fine sandpaper, or switch to slip-fit style connectors for easier use.
Sewer hose without fittings is rare - buy cheap complete kit and swap fittings, or try industrial bulk hose. Consider repairing leak with hose clamp or sewer hose repair tape.
Your RV sewer hose will likely freeze at 25°F, especially with the uphill section that creates standing water. The two-inch rise at your hookup point is particularly vulnerable to freezing.
A slow-draining gray tank is typically caused by grease buildup, soap residue, or debris in the tank or drain pipe. Most issues can be resolved with tank flushing, valve cleaning, or using specialized RV tank treatments.
