Great value direct from source
Buying direct saved me a lot compared to local supply houses. The packaging was secure, and every component was present. Highly recommend for DIYers and pros alike.

Perfect for my HVAC project
Needed a reliable distribution point for underfloor heating. The flow meters are accurate and easy to balance. No issues with the fittings connecting to my PEX tubing.

Good product, instructions could be better
The manifold itself is solid and leak-free after pressure testing. However, the included installation guide was a bit vague on torque specifications. Overall happy with the purchase.

Excellent build quality for the price
Installed this manifold in a new basement renovation. The PP-R material feels very durable and the ball valves operate smoothly. Direct from manufacturer shipping was faster than expected.

Solid performance
Been running for three months now with no leaks or pressure drops. The only reason for 4 stars is that one of the mounting brackets was slightly bent, but it didn't affect installation.

Professional grade equipment
As a contractor, I have installed many manifolds. This Woximiller unit rivals brands that cost twice as much. The brass inserts are well-seated and the plastic housing is robust.
Q: Are replacement flow meters available if one gets damaged?
A: Yes, we sell individual replacement flow meters and valve cartridges. Please contact our support team with your order number for assistance.
Q: Is this manifold compatible with oxygen-barrier PEX tubing?
A: Yes, this PP-R manifold is fully compatible with standard oxygen-barrier PEX, PERT, and PB tubing commonly used in underfloor heating systems.
Q: Does this come with automatic air vents?
A: Yes, both the supply and return bars are equipped with built-in automatic air vents to facilitate easy system bleeding and maintenance.
Q: What is the distance between the center of each port?
A: The center-to-center spacing between each loop port is standardized at 50mm (approximately 2 inches) to ensure easy pipe routing.
Q: Can I use this for a radiant cooling system as well?
A: Absolutely. As long as your system operates within the temperature and pressure limits (max 95°C and 10 Bar), this manifold works for both heating and cooling applications.
