TOTO TH679A CHECK VALVE / NON-RETURN VALVE – 2 NOS., INSTALLED WITHIN MIXER FAUCET ASSEMBLY. PROVIDE TO PREVENT BACKFLOW BETWEEN HOT & COLD WATER SUPPLIES.
Important
The exact installation position and orientation depend on the TOTO faucet/mixer model. TOTO lists TH679A in assemblies such as TMN40BT2B, TMN40BT1NB and TMF40ASZ, among others.
If you give me the TOTO sanitary/faucet model number, I can prepare the as-built drawing information including connection size, location, quantity, dimensions and a simple schematic detail for TH679A.
