Material selections such as Viton and Hastelloy c-276 ensure that FlowVis® will provide many years of trouble-free
operation in normally treated, sanitized pool water conditions. However, certain brands and designs of inexpensive
chlorine feeders are known to fail and release high concentrations of chlorine or even chlorine gas into the
surrounding filtration system. When this occurs, any equipment that comes into contact with these abnormal levels
of chemicals, will experience rapid and catastrophic damage. Inspection of any failed components will quickly and
conclusively confirm the cause of the damage, and under these circumstances, the product’s warranty will be void.
Under no circumstances should FlowVis® be used as a ‘check valve’ to prevent the eects of these Chlorine Feeders
damaging other equipment such as Heaters.
COMPATIBILITY
When using the ‘retrofit’ models listed in Table 3 on
page 3, it is important to note that each manufacturer’s
valve body design has a unique hydraulic
characteristic that will result in a specific FlowVis®
calibration scale being required. It is therefore
important that you select the correct FlowVis® model
for the particular valve body that is installed in your
system.
