Pro Advice: Several Tips When You Install the Kitchen Sink

  1. Make careful choices and consider the material when buying a basin sink. The material of your sink may influence how your basin can be installed. One frequently recommended choice is stainless steel sink because it is easy to fix and more solid.
  2. There are a few necessary preparations to make before you install the sink. The first thing is to drain the water in the pipes in advance to keep them water-tight and immune from rust. You should also clean the countertop, remove old putty and polish the cut to ensure that your sink fits into the opening.
  3. After the installation of the sink is completed, do not use it immediately. Before plumbing your kitchen sink, you should wait for a period of time to let the putty dry, thus preventing the moisture from penetrating the connections. After that, flush the pipes to remove the sediments.
  4. Check the connections with a drainage test. Firstly, fill the sink with water. Then, check whether all the connections are sealed and make sure that there is no water leakage. You can put a towel on the connections, particularly those that are near the tubing, the drain, and the trap to see if the towel is dampened. If there are leaks, carefully turn the nuts until the leak is stopped.
  5. Clean the cement, caulk, or putty left on the countertop. If they are not removed in time, they may dry out and leave stains, destroying the overall beauty of your kitchen. You can apply detergents and wipe them away with dampened cloth.
