Details

The full rundown

A bladder-type accumulator tank that holds water under pressure. It smooths out flow, stops pulsing at the tap and means the pump cycles less often.

Why it works

  • Smoother water flow: Reduces pulsation for consistent pressure at the tap.
  • Longer pump life: Minimises rapid cycling and wear on the pump.
  • Lower amperage draw: Improves overall system efficiency.
  • Noise reduction: Dampens vibration and pump hammering sounds.
  • Simple installation: Compact design fits easily into carava n and camper plumbing layouts.

What's in the box

  • 1x Accumulator Tank
  • 2x 1/2" BSP Barb Fittings

How it works

The accumulator uses an internal bladder that stores water under pressure. As you open a tap, water is released from the tank before the pump activates, reducing on/off cycling and stabilising flow. Before installation, the bladder's pre-charge pressure is set slightly below your water pump's output pressure to ensure proper performance.

What it suits

  • Suitable for 12V caravan, campervan, RV, and marine water systems
  • Works with diaphragm-style water pumps
  • 1/2" BSP female fittings for simple inline connection
  • Ideal for both new installations and upgrades to existing plumbing

Fitting it

Easy (2/5) Mount using the two anti-vibration screw points, adjust pre-charge pressure, and connect using standard 1/2" BSP fittings.

Features

  • Bladder-type storage: Maintains stable pressure and smooth output.
  • Anti-vibration mounts: Rubber grommets reduce noise transmission.
  • High working pressure: Rated up to 125 psi (8.6 bar).
  • Compact size: Easy to position in tight service spaces.

Thanks for the replacement, it works perfectly

From the Treklo crew

G'day, we're Treklo

We're a handful of blokes in Geelong who spend our weekends in utes, vans and campers. We got sick of 12V gear that gave up a few trips in, so we started making our own and running it in our own rigs first.

Not sure what you need? Flick us an email and one of us will sort you out. No sales script, just straight answers.

  • We run it ourselves

    Every bit of gear goes in our own rigs before it goes on the site.

  • Out the door today

    Order by 3pm AEST and it leaves Geelong the same day.

  • Sorted here if it plays up

    1 year Aussie warranty, handled by us, not a call centre.
