Dual sink vanities that are space permitting offer several advantages in the kitchen and in the bathroom of a house. As long as the pipework is done correctly by a professional, these dual sinks require minimum maintenance and incur very few problems. Read further to learn about some common problems users face with dual sinks and how an expert would advise to solve these difficulties.
- How come the dual sink vanity does not provide cold water even though other water outlets in the house are providing sufficient cold water?
This is probably because the cold water pipeline leading to the dual sink may be frozen. To fix this issue without causing pipe fracture, open the cold water faucet and place a small electric heater just below the vanity. If this does not help in thawing out the pipe and allowing the cold water to flow, it is best to call a professional plumber to fix the issue.
- Why is there very low water pressure in one faucet (both hot and cold sides) of the dual sink?
This problem usually occurs when an aerator is clogged. The aerator connected to the spout providing less water pressure has to be unscrewed and cleaned. In doing so, be careful of the small plastic parts inside it. Once you have cleaned the screen, replace the aerator in the same way and your problem should most likely be solved.
- How to clean a clogged disposer in a dual sink?
When the disposers in a dual sink are clogged and if there is any pipeline connection to your dishwasher, this will lead to the water in the dishwasher backing up and not draining properly.
To solve this problem, remove the pipe which exits the disposal and clean it properly. The dishwasher water drains into this same disposal so once the pipe is cleaned, the dishwasher water will drain away completely.
- Can I install a dual sink where there is only one set of pipelines?
Yes, you can do so, provided you install a water splitter first. Place the device on the existing shut off point so that the water will split into two faucets for your dual sink.
- Why is the drainage of one sink more efficient than the other in a dual sink vanity?
This may be confusing especially because both sinks are draining into the same line, so one would wonder how this could happen. In a dual sink, both drain arms are horizontal at first and then join a vertical pipeline. There could be some sort of obstruction in the horizontal arm in the drain pipe of the affected sink. If you are observing this drainage problem only in one sink, then it is highly likely that a blockage is the problem. Try a pressure blast to clear the block. If this does not provide a permanent solution, you may have to cut off the area of the pipe that is blocked and then connect the drain to the rest of the pipework carefully.
- What is the solution to water backing up in both sinks of a dual sink vanity?
The common waste stack where both sinks dispose their waste could be blocked. Snaking the drain line will be help clear this kind of block. You could also try a chemical drain cleaner to remove the blockage.
- How to fix the issue of a dual sink which drains out the garbage disposal very slowly?
In this case, you might have already tried a drain cleaner and plunger and these may not have helped fix the issue. The next assumption is that the pipes under the sink closest to the garbage disposal are partly clogged. If so, the pipes have to be removed and cleaned. If there is no partial blockage, clean the drain line in the wall.
As you can see, clogging and water pressure problems are the two main concerns with a dual sink vanity. If you do not diagnose the problem correctly, repairing it will be difficult. Expert advice from professional plumbers can be of great help in these situations. Their experience helps in diagnosing the problem correctly and thereby providing a perfect solution to the problem.
