Replacement of PVC valve: close the sluice gate, remove the movable handle, there is a red and blue mark of about 8 mm on the handle, buckle it down, loosen the fixing screw counterclockwise with a flat-blade screwdriver, take off the handle, and remove it with an adjustable wrench Open the valve core, open the upper part of the gland with a wrench, and take out the valve core inside. The standard one is a decorative cover under the handle, and there is a small screw inside, the standard turnbuckle is a hexagon, and the non-standard one is a slot, and then the decorative cover is unscrewed by hand (this decorative cover is a plastic hand-twisted) not bad). Unscrew the large screw with an adjustable wrench, use a screwdriver to loosen the screw that locks the switch, then remove the old switch and install the new switch in place.
