Uneven water flow, low pressure when the pressure at other faucets seems all right, or troublesome switching back and forth from spray head to sink spout can be caused by a malfunctioning diverter valve or by a restricted hose.
Remove the spout from the faucet body by hand or tool. Fill in vinegar to the water diverter till half full condition. Clean the diverter valve with vinegar and a soft brush. However if the mineral clog is heavy to remove, keep the vinegar inside the diverter for 12 hours or more to work as dissolvent.
Cause. Spray buttons on sprayhead have worn out. Over time, dirt and debris collect in the sprayhead causing the internal diverter to no longer divert water properly between the different spray functions.
A faucet diverter valve is a plumbing mechanism that lets you “divert” (or redirect) water from your bathtub faucet to your showerhead and back. You can also use it to switch back and forth between the kitchen faucet and the faucet sprayer. In either case, it allows water to be diverted from one spout to another.
A diverter valve is a mechanism in a combi boiler that opens or closes to direct hot water either to radiators or taps and showers. A diverter valve may be faulty if your water is lukewarm, if your hot water taps work but your central heating does not or if your hot water taps only work when the central heating is on.
One of the most frequent complaints of a faulty diverter valve is hot water running cold, or lukewarm. The combi boiler should prioritise hot water outlets when in use and not your heating, however, if the valve is slightly stuck open, the water flow rate may not be adequate to provide the necessary heating output.
Spray Misting From Faucet
Use a cloth or a brush to remove minerals, tape or debris from the aerator, as it could be clogged. Be sure to also check the aerator washer. Reinstall the aerator and check again. If the problem still shows up you will need to replace the aerator as it might be cracked or damaged.
The most common reason is that spinning faucet handles can be caused by general wear and tear on the faucet stem, otherwise known as the faucet cartridge. This part can be replaced by removing the faucet from the sink and inserting the new cartridge.
Well, once you've found the diverter valve, simply run your tap water on hot and keep an eye on it. When hot water is run, the valve should close. If it doesn't move then you've got yourself a stuck diverter valve.
We wouldn't recommend fixing the diverter valve yourself. If you think there's a problem, you should call a suitably qualified engineer to have a look at it for you.
There are two common incidents that can cause this to happen. You can remove the side sprayer and soak in 50/50 vinegar and water solution for several hours to clear them out. The second common cause is the hose underneath are compromised and bent. Lastly, the issue could be a blocked or damaged diverter assembly.
This can be caused by a variety of factors, including sediment or mineral buildup, a faulty valve or diverter, or a clogged aerator. One possibility is that the aerator, which is the small screen located at the end of the faucet, is clogged with debris.
The mechanism that controls the flow of water is a small valve called a diverter valve. It is situated inside the body of the faucet, usually directly under the base of the swing spout, as shown in the drawing.
If the aerator still won't budge with any form of gentle movement back and forth, apply WD-40 Penetrant spray. This will clear any resistance in a short while and allow easy removal. Once removed you can soak the aerator parts in a solution of vinegar this will loosen any built up mineral deposits.
Clogged aerator
After working for a long time, all the dirt, debris, and other sediments collect and clog it. When this happens, the faucet will sputter when you turn it on.
Disturbances in the water flow can cause harmless temporary sputters. Faucets sputter as air in the pipes work its way out. If faucet sputtering continues, you might need to clean or replace faucet parts. A malfunctioning water heater can lead to inconsistent heating and sputters at the faucet.
The cost to replace a shower diverter valve falls between $20 and $200 on average. This type of valve works in the exact opposite way from a mixing valve. Water enters from one inlet and exits through two outlets. You can use a diverter to change the water flow between your showerhead or bathtub faucet.
In most cases, the diverter valve looks like a pin located on the bathtub faucet spout, but it might appear as a third handle or lever. When the valve is activated, a rubber stopper plugs the water flow and the pressure sends the water through the showerhead.
The main difference between a diverter and a transfer valve is how they direct the water supply. Diverters switch the flow of water between a tub and shower — either the showerhead or the tub faucet gets the water flow. Transfer valve sends water to multiple outlets at the same time.
After you remove the lid of the boiler, you have to locate the diverter valve mechanism. Run tap water on hot and observe the diverter valve. If you run hot water, the valve is supposed to close in order to divert it to the tap, meaning it should move. If you see no movement, then it's stuck.
Lifting the throttle releases the boost pressure into the air cleaner box. If the valve is defective or inadequate, you will get a loss of boost, extended lag or a throttle response that is sluggish. These problems go away with the installation of an aftermarket diverter valve.
