Boshart 9013FSG2J24M4 – Frequently Asked Questions
1) Will the Boshart 9013FSG2J24M4 pressure switch thread onto my 1/4 inch tank tee or pump port?
Yes, as long as the port is a 1/4 inch male pipe thread. The 9013FSG2J24M4 has a 1/4 inch FPT (female pipe thread) connection, which is the standard pump control port on most jet pump casings, tank tees, and pressure switch nipples. It mounts directly on the pump or on the piping near the tank.
2) What does the low level cutoff on this Boshart pressure switch actually do?
It shuts the pump down when system pressure drops below the point that indicates the well or supply has stopped delivering water, so the pump is not left running dry. On the 9013FSG2J24M4 that low level function is built into the switch, not a separate add-on device. Once it trips, it holds off until you reset it by hand.
3) Can I use this switch on a submersible well pump, or is it only for jet pumps?
Both. The Boshart 9013 FSG2 is a diaphragm-actuated switch built for electrically driven water pumps, and Boshart lists it for jet pumps, submersible pumps, and reciprocating pumps. It is the standard type in the 9013 line for common residential and light commercial pumping.
4) I am replacing a failed pump switch. Is 9013FSG2J24M4 a direct swap?
If the old switch is a 1/4 inch FPT diaphragm switch set at 40-60 PSI with a low-level cutoff, the 9013FSG2J24M4 drops in on the same nipple and the same two-line, two-load terminal arrangement. Where it is not a straight swap: if your existing unit has no low level feature, this one adds a trip that will shut the pump off and require a manual reset when the well draws down, which is usually wanted but it is a behaviour change on the job.
5) What is the difference between the Boshart 9013 FSG, FRG and FYG pressure switches?
FSG2 is the standard water pump switch, contacts close on falling pressure to start the pump. FRG is reverse acting, its contacts open on falling pressure, which is how you wire a low-level or transfer application that needs the opposite action. FYG covers higher horsepower and higher pressure requirements. The 9013FSG2J24M4 is an FSG2 with the low level function.
6) Do I need anything besides the switch to finish a pump control rough-in?
The switch itself covers the control; you still supply the 1/4 inch MPT nipple or tank tee port it threads onto, thread sealant, and the conduit or cord connectors for the line and load wiring. The 9013FSG2J24M4 ships as the switch only, with a 1/4 inch FPT port. A pressure gauge, if you want one at the tank, is a separate item.
7) How is the Boshart 9013FSG2J24M4 packaged for distributors?
Boshart ships it in cartons of 40 pieces, which is the stocking unit for plumbing and pump wholesalers carrying the 9013 line. Country of origin is Mexico. The manufacturer part number to order against is 9013FSG2J24M4.
