STEP 4: BACKWASHING AND FLUSHING THE SYSTEM
STEP 4-A: BACKWASH
The purpose of the backwash and flush procedure (similar to the most simple sink filter units) is to remove
media dust and fines from the system instead of going into the home and to prepare the system for usage. There
will be the occassional fleck or flake, however following this procedure will greatly reduce this issue.
Following the remaining procedures is a helpful way of checking the installation of the system. Is it plumbed in
correctly per our instructions with main supply of water to inlet, the outlet to the home and a correct bypass and
drain application?
Pressure limited to 65 PSI, with a minimum of 35 PSI (40 PSI for Iron units)
and a flow rate of at least 8 GPM (12 GPM for 1354 units).
•
After the initial “sputtering” you should get a good flow under pressure out of the drain line. The initial drain water is gray
(fines and dust). At the end of a proper backwash procedure that drain water will clear.
•
HF and 11/2” valves have greater flow characteristics and greater lift of media and make a mechanical noise as the valve
piston drives into the valve body and the flushing could produce noise. This is normal. If too loud, the automatic backwash
time can be re-set to a day time, instead of the quiet of the evening. See Instructions to Re-Set the Backwash Time.
Not getting a good flow out of the drain line?
•
Check to see if the drain line is undersized, restricted, or may travel too long (especially up & over).
•
Check to see if the water supply lines are plumbed backwards. You will get an initial, surge then a greatly reduced
flow that does not appear to be under pressure. Remember, if plumbed correctly the inlet water is under pressure.
