Tip & How-To about Washing Machines
If you are thinking of changing or upgrading your old washing machine, there is a one thing that you need to consider. The plumbing that takes the water away may have been okay for your old washer, but it may not work well for a new washing machine. Many houses have been built with 1-1/4” or 1-1/2” drain standpipes for washing machines. While these pipes were entirely okay for the washing machines that they were to serve, they are no longer okay for many of the new washing machines of today.
The new front load and many of the new top load washers are now using a separate pump for removing the water from the washing machine. This is great for getting the water out faster, but the water goes out so fast that the piping is no big enough to handle the volume of water that is being pumped.
For many of the new washers you need to have a 2" standpipe and trap... the older 1-1/2" standpipes and traps will not handle the higher volume of the new pumps. Because of this, you will have to also upgrade your plumbing to make sure that your new washer will not flood you out when it discharges the water from the machine.
The plumbing is often easily accessible, but in some cases it is not that easy. When possible change the plumbing from the main trunk line to the washer with a new 2” trap and pipe. If a total change is not possible, then get the pipe as big as possible as close as possible to the trunk line. This will give you at least less resistance to water flow and give a reserve space for the water to go to. The most important part is the trap as this creates the most restriction to the flow of the water. Also getting the pipe as high as possible where it dumps in at, will help, but check on the maximum height limitations of your washing machine. If you get the pipe too high the washer will not be able to pump the water high enough to get it over the top and into the pipe, creating yet another problem for you.
By checking all this out before you purchase that new washing machine, you can save yourself a lot of headaches later.
