A mixing valve is a device that combines hot and cold water in a faucet or shower, to provide for a safe and comfortable water temperature. These mixing valves can automatically control the hot water temperature and are usually placed in a central location so as to control the flow throughout the house. Sometimes mixing valves can also be used for one particular outlet such as a shower. When the mixing valve creates problems, they can often be very confusing and may need expert help.
- What happens when a shower mixing valve does not provide hot water?
Maybe the cartridge has to be adjusted or the mixing valve is now old and needs to be replaced. In cleaning the cartridge, you have to remove it first and then flush out debris from the line by turning on the water supply. Be careful while clearing the line of trash so as to avoid flooding the area. When replacing the mixing valve system, look out for one that is similar to your existing one.
- What could be the problems with connecting a mixing valve to volume control valves so that you have the option of using it without a diverter?
Ideally, when a small pipe flows into a larger one, the pressure will drop. If the water pressure flowing through the pipelines is fairly good, no obvious problem may appear with this installation. If the water pressure is lowered to less than a preferred level, half-inch pipes, along with three-quarter inch to half inch couplings can be used. A preferred alternative is to replace the half-inch supply pipe with three-quarter inch pipes, which connect back to the meter. This may require more work but the resulting water flow would be much better.
- Why is there barely any water coming from a shower head that has a mixing valve attached to it?
To check this problem, you may have removed the shower head and replaced only the spindle. In this case, there could be two reasons for the problem. One is that the volume control spindle may be failing, and the other could be that the diverter is wrong. To understand this, you should know that the shower-only mixing valve units and the tub/shower units have the same valve but the diverters are different. If you have installed a tub/shower diverter spindle instead of a volume control one, this particular problem would occur.
Another possibility is that maybe the valve body is clogged. In this case, the valve body needs to be replaced.
Mixing valves play an important role, particularly in tub/shower and shower-only units. There can also by many different kinds of mixing valves used for other specific purposes or on specific fixtures. Problems with mixing valves can lead to complications in water flow and pressure. For this reason, mixing valve troubleshooting is extremely essential. For correct troubleshooting and solutions to mixing valve problems, it is best to seek help from a professional plumber. They can provide a quick and affordable solution to the problem.
