DN15 blue copper single flow rate mechanical water meter installation video DN15 blue copper single flow rate mechanical water meter installation video introduction Conclusion First: install the core four elements Correct direction: The arrow on the water meter must be in the same direction as the flow of water. Position horizontal: The water meter must be mounted on a horizontal pipe with the dial facing up and the reading clear. Straight pipe section requirements: there must be a straight pipe section ≥10 times the pipe diameter before the water inlet of the water meter, and a straight pipe section ≥5 times the pipe diameter after the water outlet to ensure accurate measurement. Easy maintenance: the valve should be installed before and after the water meter for future maintenance or replacement. Detailed operation steps Step 1: Prepare Tools: Pipe pliers, adjustable wrench, raw material tape (Teflon tape), level, tape measure. Materials: WATER METER, two GLOBE VALVES (or GATE/BALL VALVES), necessary stubs and elbows. Safety: Be sure to shut off the main water source and make sure there is no standing water in the pipe. Step 2: On-site inspection and planning Check specifications: confirm that the water meter model and diameter are consistent with the pipe specifications. Reserve SPACE: CHECK that the installation location meets the requirements of the straight pipe section (see Core element 3 above) and leaves enough space for valve operation and meter reading. Determine the direction: clear the direction of water flow in the pipe, ensure that it is consistent with the direction of the water meter arrow. Step 3: Pipeline processing and pre-installation Clean the pipe: clean the burrs, debris and rust at the pipe interface. Pre-assembly: The water meter, valve and pipe fittings are pre-assembled on the ground to check whether the connection is smooth and the length is appropriate. Step 4: Formal installation Wrap the raw material belt: at each external thread interface, wrap the raw material belt clockwise for 5-8 turns, and the tail should be in the direction of tightening when wrapping to ensure sealing. Connect the inlet valve: SCREW the inlet valve into the pipe and tighten it with pipe pliers or wrenches. Connect the water meter: Connect the inlet of the water meter (usually marked with

Step 4: Formal installation Wrap the raw material belt: at each external thread interface, wrap the raw material belt clockwise for 5-8 turns, and the tail should be in the direction of tightening when wrapping to ensure sealing. Connect the inlet valve: SCREW the inlet valve into the pipe and tighten it with pipe pliers or wrenches. Connect the water meter: Connect the inlet of the water meter (usually marked with "IN" or the end pointed by the arrow) to the water inlet valve and gently tighten it with a wrench, taking care not to damage the meter with excessive force. Connect the water outlet: connect the water outlet of the water meter with the water outlet valve, and gently tighten the same. Check the level: Use the level to check whether the water meter is installed horizontally. Step 5: Test and acceptance Slow water: first slowly open the water inlet valve, and then open the valve in front of the water meter, let the water slowly fill the pipe, observe whether there is water leakage. Comprehensive inspection: confirm that there is no leakage at all interfaces, and then open the valve behind the water meter to restore normal water supply. Check metering: Observe whether the meter pointer or number is turning properly while using water. Risk and plan Risk 1: Water leakage Reason: improper wrapping of raw material belt, untightened interface, damaged pipe fittings. Plan: Close the valve immediately, rewind the raw tape or replace the damaged pipe fittings. Risk 2: Inaccurate measurement Reason: the straight pipe section is not enough, the installation is inclined, there are bubbles or sundries in the pipeline. Plan: Check whether the installation conforms to the specifications, try to drain water and exhaust. If the problem persists, contact a professional. Risk 3: Damage to water meter Reason: excessive force during installation, hard impact inside the pipe. Plan: When installing, be sure to use a special wrench to jam the hexagonal position at both ends of the water meter to avoid directly screwing the case. Clean pipe before installation.
