In the previous article, we have a preliminary understanding of some basic knowledge of angle valves. In this article, we mainly introduce the installation precautions, key points of purchase and cleaning methods of angle valves.
Precautions for installing angle valve
- Professionals are invited to install it, and it is required to install it in a place with good water, so as to avoid accidental losses;
- Before installation, please be sure to clean the sand and sundries connected to the outlet pipe to prevent the ceramic chip from being jammed and resulting in water leakage;
- When installing, do not hold the handwheel of the angle valve with your hands and rotate it to tighten it. You should wrap several layers of cloth or paper towels on the valve body, and then clamp the valve body with a wrench and rotate it to tighten it. If the valve body is directly clamped without wrapping the buffer, it may scratch the surface of the angle valve and affect the appearance;
- After installation, the main valve should be opened to enter water, and check whether there is any leakage in the angle valve. Generally, the water should be pressurized for about 15 minutes to confirm. If the angle valve is not installed in the water pipe, the angle valve should be closed.
Angle valve selection points
1.Look at the material
The best copper material is relatively heavy, and the excellent material greatly prolongs the service life of the product; although the zinc alloy on the market is relatively cheap, it is easy to break after a year of use, and maintenance is uncomfortable.
2.Look at the spool
The spool is generally made of ceramic spool, the spool is the heart of the product, it is tightly closed and the life span depends entirely on it, especially the sealing ring and ceramic piece inside! But generally we can't see it, so we have to try the feel, the feel is too heavy, the switch is uncomfortable, the feel is too light, it will leak in a short time! The soft touch has a longer lifespan.
3.Look at the plating gloss
Look at the gloss of the electroplating, pay attention to the gloss, whether the product is blistered or scratched, the surface of a good product is smooth and shiny, and it is smooth and flawless to the touch.
4.look at the brand
The most important thing to buy an angle valve is to look at the brand. Generally, the standard angle valves of big brands are more guaranteed in terms of quality and service. Don't buy "three noes" products for convenience or cheapness at will, so as to avoid no way to claim when a problem occurs.
How to clean the angle valve blockage
Step 1: Unplug the socket and close the two triangle valves.
Step 2: Unscrew the nut of the hot water port, block the hot water port, and prevent the water from the water heater from flowing out. At the same time, unscrew the nut of the cold water outlet, connect the hose (the shower pipe is enough) to drain the water until no water flows out of the cold water outlet. For a 50L water heater, drain for about 1 hour.
Step 3: Remove the hose connected to the cold water outlet, connect one end of the hose to the hot water outlet and the other end to the faucet, turn on the faucet to fill water for 1 minute, and plug the cold water outlet, let the cold water stay in the inner tank for a while , and then open the cold water outlet to drain, repeat several times until the drained water is clean.
Step 4: Screw on the nuts of the cold water port and the hot water port, open the triangular valve, and turn on the hot water from the faucet of the water heater. After the water flows out, close it.
