Frequently Asked Questions - MasterFlush MF 7160 DOMETIC

What is the difference between models MF 7160 and MF 7260?
The MF 7160 is a standard bowl while the MF 7260 is a compact marine bowl. Dimensions and seat height differ slightly (see specifications).
Can I use pressurized fresh water for flushing?
No. Do not connect the raw water flush (models 7160, 7260) to a pressurized onboard water system. This could cause the pump to run continuously and flood the boat.
How to install a vented loop?
If the toilet rim is less than 8 in (20 cm) above the waterline, install a 0.75 in (19 mm) vented loop on the water supply line, with a built-in check valve, at least 8 in above the waterline.
What is the maximum discharge height?
The maximum discharge height is 4 feet (1.2 m). The horizontal run must not exceed 40 feet (12.2 m). These distances are not cumulative.
How to clean the toilet?
Use non-abrasive cleaning products. Make sure the water supply is open. Avoid harsh chemicals that could damage seals.
What to do in case of water leak?
Check all connections, tighten hose clamps if necessary. If the leak persists, inspect seals and replace defective parts.
Can I install a tank level controller?
Yes. Dometic recommends using a 'full tank' stop relay (DTM01C or DTM04) to prevent overfilling the tank.
What are the recommended hose diameters for discharge?
Use a hose of 1.5 in (38 mm) or 1.0 in (25 mm) inner diameter. For seawater, the inlet hose should be 0.75 in (19 mm) ID.
How to rotate the bowl?
Loosen the compression band, remove the plastic collars, lift the bowl, rotate it to the desired position, then retighten the compression band to 65 in·lb (7.3 Nm).

WARNING: Flooding hazard. Failure to obey the following warnings could result in death or serious injury.

  • If the toilet is connected to any through-the-hull fittings, properly installed seacocks must be installed in all piping connected to through-the-hull fittings. Seacocks must be easily accessible to all users of the toilet or secondary valves fitted in hoses where they are easily accessible. All valves must be full bore valves and of marine quality. Screw-to-close gate valves are not recommended.
  • If the toilet is connected to any through-the-hull fittings, all flexible hoses must be of marine sanitation quality and must be secured to any fittings (such as those at seacock, vented loop or toilet) with two stainless steel, worm-drive hose band clamps at each connection. Connections must be checked frequently for integrity.
  • If the toilet rim is ever less than 8 in. (20 cm) above the highest possible waterline at any time (during any conditions of heel, load, or trim) and is connected to any through-the-hull fittings, properly positioned ventilated (vented) loops must be installed in intake (if connected to raw water) or discharge piping to prevent potential back siphonage of seawater into the boat. Vented loops must be equipped with integral check valve that permits air into line to prevent siphoning.
  • If toilet uses raw water for flushing at any time, a raw water pump controlled by an automatically operating demand switch must not be installed. If the onboard water valve or any plumbing connections were to leak, the automatically operated pump would start and could flood the boat.
  • Do not connect raw water flush toilet (models 7160, 7260) to an onboard pressurized water system.
  • Before beginning any work on this product, be sure that all electrical power to the unit has been turned off and that the seacocks are in the closed or off position.

Dometic MasterFlush toilets operate with Dometic DTM tank monitor systems (available separately) to shut down electrical power to the toilet when the holding tank is full. This prevents overfilling the holding tank. Refer to the toilet system wiring diagram on the parts list.

  1. Route the input power wire from full tank relay of the DTM panel to the flush switch location.
  2. Follow the flush switch installation instructions on page 11 beginning at step 10.
