Grey water tank & HP air additions - '72 D22C

[JCMAC]

  I installed a 35 gal gray water tank (Plastic-Mart.com) to comply with the CA and AZ laws.  Also added a high output air compressor to provide water pressure in the coach and be able to inflate the tires!
  The black water tank had its own valve and I added a new valve to the main discharge also. Now the grey water backs up in the existing black ABS piping until it reaches about 6" below the floor and a new saddle tee I added there, which the directs the grey water down and back to the new grey water tank.  A sensor reads the level in the coach and a seperate drain is piped to behind the RH rear tire.
  The VIAIR 450C air compresor (in the back RH corner) is wired and piped to either a pressure regulator for 25 psi coach water or can be switched to a small tank for a 90 psi (max) air for tires.
