Pallas Viva RO Booster Pump - 75gpd

This is the booster pump for Pallas 5 and 6 Stage Viva reverse osmosis systems, rated to support a 75 GPD membrane. WrekinWater supplies it as a genuine replacement when the original pump on a Viva system weakens or fails, restoring the extra pressure the membrane needs to produce water at its rated capacity. It's an electrical component fitted before the membrane in the RO train, not a part intended for non-Pallas systems.

Signs this needs replacing

• Water production has slowed noticeably or the storage tank takes far longer to fill.
• The pump is silent or you can't feel it running when the system is producing water.
• Taste or TDS has worsened alongside slower flow, suggesting low membrane pressure.
• The pump hums or buzzes but doesn't seem to be moving water.

Mains water pressure alone often isn't enough to drive a 75 GPD membrane at its rated output, so the booster pump raises the pressure feeding the membrane to get the flow and rejection rate the system is designed for. As the pump wears or its motor weakens, pressure drops, production slows, and the membrane works less efficiently even if it isn't itself at fault. Because it's a powered component plumbed into the RO line, a failing pump affects both output and water quality.

WrekinWater is a family-run water treatment retailer based in Bettisfield, Shropshire, with more than 50,000 customers served over 15 years and an "Excellent" Trustpilot rating. We stock the specific Pallas Viva pump so your system is restored to its proper boosted pressure rather than run on an ill-fitting substitute.

How to replace it

1. Isolate electrical power to the RO system and shut off the mains water feed before starting.
2. Open the dispensing tap to relieve pressure until water stops flowing.
3. Disconnect the push-fit tubing and the low-voltage power lead from the old booster pump.
4. Unscrew or unclip the pump from its mounting bracket and remove it.
5. Fit the new pump in the same orientation and reconnect the tubing and power lead securely.
6. Restore water and power, check every connection for leaks, and if you're not confident with the plumbing or wiring, ask a qualified water treatment engineer to fit it.
