View part detailsThetford Sani-Con Turbo 500S & 700 — Parts Diagrams
The Thetford Sani-Con Turbo 500S and Turbo 700 are RV waste-discharge systems that use a macerator pump to send wastewater through a compact discharge hose. The two versions share some nozzle and hose service parts, but their pump assemblies and mounting arrangements differ. Check the exact system model before ordering.

How to identify the Sani-Con system
Thetford identifies the complete Turbo 500S as 97587 and the Turbo 700 as 97500. The model label or serial-number plate identifies which system you have. A 500S pump is not the same as a 700 pump-and-tank unit. See Thetford's model and serial-number identification sheet (PDF).
Sani-Con Turbo 500 / 500S parts diagram
The 500S uses a stand-alone pump connected through a three-inch inlet coupling. In the drawing, the replacement pump is item 1, the switch box is item 2 and the discharge hose and nozzle are items 3, 6 and 7.

Sani-Con Turbo 700 parts diagram
The Turbo 700 has a pump built into its wastewater tank-housing arrangement. Its factory replacement pump is 97518 (pump with tank housing), not the 500S 97540 pump. The round access cover is a separate service assembly, part 97517, containing its screws and O-ring.
| Diagram no. | Thetford part | Component |
|---|---|---|
| 1 | 97518 | Pump with tank housing |
| 1 | 97519 | Tank housing only |
| 2 | 97514 | Nozzle-cap and gasket kit |
| 3 | 97517 | Access cover, screws and O-ring |
| 4 | 97520 | Discharge nozzle with clamp |
| 5 | 97521 | 21-foot hose, nozzle, clamp and coupler |
Which replacements are shared?
Both factory parts lists identify 97514 for the nozzle-cap kit, 97520 for the discharge nozzle with clamp and 97521 for the 21-foot hose assembly. The 70400 nozzle with cap is a separately numbered Sani-Con accessory; do not assume it is the same kit as 97520.
Choosing a pump or fixing a leak
For a 500S, compare the 97540 replacement pump with your existing pump and wiring. A 700 uses a different pump/tank-housing assembly. If wastewater is escaping near a 700 pump access cover, use the 700 drawing to identify part 97517 rather than ordering only by O-ring size. If the hose-end connection is leaking, compare the nozzle, caps, gasket and clamps with the factory illustrations.
Before servicing a waste system, isolate 12V power, follow Thetford's flushing and sanitation procedures, and avoid working on pressurized or contaminated hose connections. For wiring and installation instructions, use the 500S support manual or 700 support manual.
