Maintenance is often a necessary evil -- most people don't like doing it, but the less it's done, the worse the consequences. Here are some observations about ten of the most common hassles encountered in wastewater pumping applications and how to avoid (or at least reduce) them.
4. There's no such thing as "non-clog"
Shall we go looking for unicorns, too?
5. Is this real life? Or is this just fantasy?
Anyone who insists that
a pump is "non-clog"
clearly hasn't seen the kinds of things
real people dump down the drain
30. Total cost of a clog
Cost of pump downtime
Cost of extraction
Cost of labor (service charges or your own time)
Cost of transit
Cost of unclogging
Cost of parts
Cost of bypass pumping if required
Cost of sewer backup risk
Cost of reinstallation
31. And one very important cost
The opportunity cost of your time
32. Opportunity cost
You might be a pump specialist
You might be a jack of all trades
Either way...
104. Ask: Are the sensors useful?
For submersibles:
Do moisture sensors give you time to react?
For ODP/TEFC:
Is it worth doubling or tripling the cost
of an off-the-shelf motor?
154. Compounding costs can ruin a great system
Decide what you need
Measure the total costs
