The pressure tank and switch decide when the pump runs. When either goes wrong, the pump pays for it: it starts and stops every few seconds, thousands of extra times a week. Fixing the tank or switch is far cheaper than the pump it saves.
Call (321) 220-9883Signs it's the tank or the switch
- The pump clicks on and off rapidly while a tap or zone is running.
- Pressure surges up and down in the shower.
- Tapping the tank sounds dull all the way up (it's full of water, no air).
- Water spits from the air valve on top of the tank.
- The pump won't kick on until someone taps the switch.
- Pitted or burnt contacts inside the switch cover.
What gets done
- Air charge check and recharge, set a little under the switch's cut-in pressure.
- Tank replacement when the bladder has failed. Waterlogged tanks don't stay fixed.
- Switch replacement for burnt or pitted contacts, or a clogged pressure tube.
- Settings checked so the pump runs fewer, longer cycles.
Do sprinkler systems have tanks?
Many Melbourne irrigation pumps are started by the timer through a relay and have no tank at all. Others run on a pressure switch with a small tank, so hoses and hose bibs work. If yours cycles when nothing is on, there's a leak or a tank problem worth checking.
Common questions
How long do pressure tanks last?
Many last 5 to 15 years. Once the bladder fails the tank waterlogs and needs replacing.
Can I recharge the tank myself?
With the pump off and the tank drained, you can check air pressure with a tire gauge. If water comes out of the air valve, the bladder has failed and the tank needs replacing.
Is short cycling urgent?
Not an emergency, but it wears the pump out fast. Get it looked at within days, not months.
