Possible Problem
Solution
A. Neutraliser overcorrects upon
installation or after replenishment.
1. The inlet bypass can be partially closed
to allow untreated and treated water.
Periodically test treated water pH and open
bypass valve when pH begins to drop.
B. Neutraliser fails to increase pH upon
installation.
1. Make sure bypass valve is closed.
2. Test water or have it tested via third
party. If high hardness or total dissolved
solids (TDS), seek alternate means of
treatment such as feeding a solution of
soda ash or caustic soda.
C. Neutraliser fails to increase pH after
being in service.
1. Check filter bed for cementing or
channelling. Break channelling or
cementing with stiff rod or tubing.
D. Excessive pressure drop.
1. Check untreated water for sediment,
silt or sand. Install sand trap or multiple
cartridge filter prior to neutraliser.
2. Check the inlet is connected to the port
labelled "upflow".
