repair or replace
[u][color=#810081]http://www.bellgossett.com/literature/files/1427.pdf[/color][/u]
page 12 says it all for me..."SCHEDULE:
• Blow down weekly (at least once) when the
boiler is in operation.
• Disassemble and inspect annually. Replace
the low water cut-off if it is worn, corroded,
or if components no longer operate properly.
• Inspect the float chamber and equalizing
piping annually. Remove all sediment
and debris.
• Replace every 10 years. More frequent replacement
may be required when severe conditions
exist such as rapid switch cycling, surging water
levels, and use of water treatment chemicals.
It is too critical of a device to not be sure if it will work.
If it was me, if I were thinking about repairing the switch, I would take it all apart and make sure there isn't any debris or buildup anywhere.0 -
Clean the low water cut-off
and replace the switch, you should be all set after that. Just make sure the Sylphon Base Assembly (Float) does not have water in it if so replace it. Make sure to instruct the customer how to blow down and remove the spring loaded # 14 blow off with the new flush version.0
