Frequently Asked Questions

Will this pump improve my shower pressure?

The UPA25-150 can improve pressure in suitable low-pressure domestic water systems, including gravity-fed installations. Suitability depends on the existing plumbing arrangement and flow requirements.

Can it boost both hot and cold water?

Yes. The UPA25-150 is designed for hot and cold water pressure boosting, within its specified temperature range.

Does it operate automatically?

Yes. The integrated flow sensor enables automatic operation when sufficient water flow is detected.

Can the UPA25-150 be installed in any position?

No. The pump must always be installed with the motor shaft horizontal, regardless of whether the pipework runs vertically or horizontally.

IMPORTANT INSTALLATION WARNING: Installing the pump with the motor shaft vertical can cause extremely rapid pump failure, potentially almost immediately after startup. Correct installation orientation is essential.

Always follow the manufacturer's installation instructions and the indicated direction of water flow.
