Score Breakdown
This verdict is based on the manufacturer's stated specifications, the current Amazon listing and its product images, the confirmed materials and design, real buyer ratings, and our research into the product category. Scores are consistent editorial judgments, not laboratory measurements, and we did not receive a paid sample.
Key Features
Fits tanks with diameters up to 16 inches.
Automates pump on/off cycling at those pressure points.
Relief valve must be adjusted to 75 PSI before use.
Simplifies draining lines for plumbing work or tank swaps.
Corrosion resistant, leak-free and lead-free.
Design and Build Quality
The tee itself is made from brass the brand states is corrosion resistant, leak-free and lead-free. The full kit measures about 12.5 by 5.9 by 3.5 inches and weighs about 5.37 pounds.
The included pressure switch is rated to cycle the water pump on and off at 40/60 PSI points, while the relief valve is designed to release pressure if the switch fails, and the drain valve is intended to help empty the lines for plumbing work or tank replacement.
Performance in Everyday Use
Miumoon states the relief valve ships unset and must be manually turned to 75 PSI before use, which the brand notes is safe for tanks rated 100 PSI or higher and compatible with both 30/50 and 40/60 PSI switches. The brand recommends checking existing plumbing before installing the new tee.
