Steps to install grommets:  Note that your pipe size will determine which size grommets you will need to install.

1) Mark the tank exactly where you want to place the grommets (double check your measurements to prevent an error)

2) Make a starter hole for your hole saw

3) Then cut your tank hole with the hole saw

4) Deburr the hole (important to create a tight seal)

5) Push short end of grommet with your hand into the hole till flush (check all sides to make sure seated smoothly

Steps to install sensors in standard formation.  Sensors are used to measure water level.  (please check w/tank manufacturer if unsure of where sensors should be placed)  Note:  Keep sensors at least a fingers-width from edges so probes/sensors seal properly).  Sensors are easy to install and are helpful to keep track of your tank levels.

1) Mark the tank exactly where you want to place your probes at end of tank (double          check your measurements to prevent an error). 

    a) Probes/sensors are typically placed at the end of the tank at top center (to                      measure when tank is full)

    b) Next probe is placed at the middle end of tank between the middle and side of              the tank (to measure when the tank is half-way full)

    c) The next probe is placed at the bottom towards the right corner (to measure when          the tank is empty)

   d) The last probe is placed at the bottom towards the center (to measure again when          the tank is empty)

2)  Now drill the 4 holes for the probes using your 3/8″ drill bit.  Remove any burrs to           get a tight seal

3)  Push probe sensor into the hole, wiggling into place then twist nut to tighten
