The first step one should take before starting the washing machine installation process is to examine existing plumbing as well as the ground beneath and the wall behind the washing machine to ensure none of these items are damaged. If any plumbing has somehow been damaged, it is important to take care of this before the new washing machine is installed. Mold, mildew, and rot can occur on the walls or floor where the old machine sat, so be sure to inspect the area carefully before washing machine installation begins.
Once the plumbing and surrounding area have been inspected carefully, read the installation directions that come with the new washer. This packet of information can cut down on the time and hassle necessary for washing machine installation. Older washing machines often featured connections for both hot and cold water, while newer machines may only feature connections for cold water. Be sure to read the instruction pamphlet to find out what type of hook-ups are available on the new washer and how to properly install them. If the new washer is cold inlet only, the hot water source will need to be turned off and sealed to prevent leaking once installation is complete.
It may be a wise decision to replace the connection hoses during washing machine installation. This is not necessarily a required step, especially if the hoses appear to be in good shape, but the hoses can eventually wear out and will require replacement at some point. Doing this process during the washing machine installation can prevent the need for another maintenance project down the line and can also prevent leaks from worn out hoses.
A common mistake many people make while installing a washing machine involves over-tightening the hoses to the washing machine. The hoses have rubber gaskets inside of them to prevent leaks, and over-tightening the hose can crack or otherwise crush the rubber gasket. This means the rubber is no longer working to prevent leaks, and water will therefore be able to leak out and cause damage to the floor, walls, plumbing, or washing machine itself. Tighten the hoses snugly, but do not over-tighten.
It may be necessary to either extend the hoses or replace them altogether with longer hoses if the new machine sits farther away from the wall. It is best to buy quality hoses; buying cheap hoses may save money up front, but they are more likely to wear out quickly and begin to leak.
