- Check the location and orientation of the tank. Ensure the tank is in the proper location so
the unit connections will line up correctly with the piping. If required, test fit the valves &
manifolds to be sure. If the unit has a side mounted manifold, occasionally tank shims are
required between the tank and the floor to ensure piping / manifold will have a minimum
of 1/2” clearance. If required, install shims before starting to load the tank. Make sure the
tank is properly installed (tripod base tanks should be secured to the floor). It is very difficult
to move a tank once the media has been loaded and may damage the tank.
- Fill the tank approximately 1/3 full of water. This will help protect the laterals from the me-
dia being poured in. Distributions tend to float up once water has been put into the tank so
confirm that the distribution is being held on the bottom of the tank and is centered. Con-
firm the riser tube is plugged so no media will enter the distribution.
- Check the media list and start from the bottom up. Ensure the proper amount of each type
of media before moving on to the next media. It is common to have additional partial bags
to add up to the required quantity of each media.
- The support bed media is first (coarse gravel first, then medium gravel followed by fine
gravel etc.). Pour the gravel so it is evenly spread out in the tank (use a circular pouring
pattern). Note that the gravel will not level out on its own when backwashed. It must be
manually levelled. To check the level, the water can be drained down until the media just
starts to poke through the water surface. This will help determine if the media is level. The
most important layer to get as level as possible is the top of the support bed , the fine grav-
el. The gravel will not move during backwash. If, for example, all the gravel has been poured
to one side, the unit will not have even flow distribution and the unit will not perform as in-
tended.
- Once all the media has been loaded, unless there are special instructions not to, the media
tanks should be filled with water to allow the media time to soak. If possible allow the me-
dia to soak for several hours, preferably over night.
