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.
