Quick overview

  • HydroQuip part 34-0178 Ordered by the factory part number, so you get the switch that was fitted originally.
  • Rated at 1 amp The switch is the 1 amp version, which is what separates it from the higher rated switches in the range.
  • Pressure sensing A pressure switch closes or opens its contacts as water pressure rises and falls, so the equipment only runs when flow is present.
  • Direct swap Replaces the existing HydroQuip switch without changing anything else in the circuit.
  • A common failure point Switches that stick, chatter or never make contact are usually the cause when equipment refuses to start or cuts out.
  • Small part, whole system The switch is inexpensive next to what it protects when flow is lost.

Product details

This is the HydroQuip 1 amp pressure switch, part number 34-0178. It is the direct replacement for the original switch, ordered by the factory number so there is no guessing about which version you are getting.

What a pressure switch does

A pressure switch watches water pressure and makes or breaks an electrical circuit accordingly. Only when there is pressure in the line does the switch close and let the equipment it protects run. When pressure drops away, the switch opens again. That is what keeps things from firing up dry.

When to replace it

Switches wear out. A contact that no longer closes leaves the equipment dead even though everything else is working, and a switch that sticks or chatters makes it cut in and out. If you have confirmed the system has proper flow and it still will not run reliably, the switch is the part to change.

Questions and answers

What people ask about this product, answered by our pool techs.

What amperage is this switch?
1 amp. HydroQuip lists it as the 1 amp pressure switch, part number 34-0178.
Is this a genuine HydroQuip part?
Yes. It is sold under HydroQuip part number 34-0178.
How do I know my pressure switch has failed?
A switch that will not make contact keeps the equipment from starting, and one that chatters or sticks makes it cut in and out. Both point at the switch once you have confirmed the system actually has flow.
Will this fit my system?
Order it by part number. If your existing switch is marked 34-0178, this is the same part. If the number differs, check with HydroQuip before ordering, because the listing does not carry a model compatibility list.
