The Monument 175C U-Gauge is a manometer designed for testing pipeline and drain systems for leaks following installation or repair work. This essential testing instrument is built from unbreakable components, making it suitable for demanding site conditions where durability is critical. The gauge tests up to 100mm (4 inch) water gauge pressure and works effectively regardless of pipe diameter, providing versatility across different plumbing and gas installation projects. This makes it particularly useful for gas engineers and plumbers who need to verify system integrity before commissioning. A practical hinged lid design allows the cover to fold back and form a stable base behind the gauge during use, improving accuracy and ease of reading when conducting pressure tests on site. The robust construction ensures reliable performance for leak detection work across drainage and pipeline applications.
