Thetford Sani-Con Turbo 700 Tank & Pump Kit 97518

When the Sani-Con Turbo 700 quits pushing waste, this is the part that brings it back. Thetford's 97518 is the complete tank housing with the macerating pump built right in, the heart of the whole evacuation system. If your pump has stopped spinning, grinds without moving anything, or the housing has started to weep at the seams, swapping in this assembly gets your rig dumping cleanly again.

Here's why folks reach for the full assembly. On the Turbo 700, Thetford builds the macerating pump into the tank housing itself, so the two really work as one unit. Part 97518 gives you both the tank housing and the pump together. There's a pump-only route out there, but if the housing is cracked or you're already in there with everything apart, doing the whole assembly once is the move that saves you a second teardown down the road.

The Sani-Con Turbo 700 is a permanently mounted, 12-volt DC waste system. The macerating pump grinds everything down and pushes it out through a 1.5-inch hose, so you're not wrestling a big three-inch sewer line at the dump station. It moves a full 40-gallon tank in about 50 seconds, and the discharge fits six common dump station inlet sizes, garden-hose adapters included. That means you can reach inlets a gravity dump could never touch, uphill or across the pad.

Who needs this? Owners whose Turbo 700 has simply worn out. These pumps live a hard life. They run wet, they run often, and after enough seasons the motor gives up or the impeller stops grabbing. Common signs are a motor that hums but won't turn, a pump that runs but barely trickles, or a slow leak forming around the tank housing. Any of those and it's time.

Installation is a bolt-in job on a system that was designed to be serviced. The assembly mounts where the old one came off and wires back into the same 12-volt feed. Take your time with the plumbing connections and the electrical terminals, and give everything a test run before you close up the bay. Every 97518 is run tested and water tested at the factory, so what shows up at your door has already proven it moves water and holds pressure. It's made in the USA and backed by a limited one-year warranty.

One note on what's in the box. This is the tank housing and macerating pump assembly. Hoses, nozzles, the discharge cap, and the wall-mounted control switch aren't part of this kit, so if any of those are damaged, plan to source them separately. The good news is that most Turbo 700 failures are the pump or the housing itself, which is exactly what 97518 covers. Match the part number to your existing unit before you order, since Thetford's Sani-Con line spans several models and the 700 assembly is specific to that system.

A couple of things from experience. Macerating pumps don't love being overloaded, so go easy on the amount of paper going down, and give the system a good rinse after each dump to keep the impeller clean. Keep the electrical terminals dry and protected, and check your hose connections at the start of each season. Treat it right and this assembly will give you years of quiet, hands-off dumping.

And if you've been limping along with a system that only half works, you already know how much of a difference a healthy pump makes. No more standing at the dump station wondering if the tank is really empty. No more babying a motor that might not start. Drop in a fresh 97518, and dumping goes back to being the quick, boring chore it should be.
