Sump and Sewage Lag Pump & Alarm Float Settings
|Printer Friendly (PDF)
We presented suggestions for the pumps off float level and the lead pump on float level in the last few articles. You may review those by clicking on the “Past Articles” area of the website.
Today we look at the lag or standby pump float setting and alarm setting. These floats must fit between the lead pump on and the bottom of the inlet. The less space between these settings, the less depth required on the sump.
The recommendation is a 6” or more between the floats. We also recommend the use of 3 floats with the lag pump and alarm at the same level. (See MMM of May 10 2010)
Next week we will begin a discussion about motor specifications.
