Appliance Repair Questions? Ask a Technician for Answers ASAP
Hi, my name is Mike and I have been in the home improvement and repair field for 20 years. I will be very glad to help you today. How old is the home? Is there a crawl space or basement below?
This is a cement slab then? How old is the home?
Where does that pipe connect? It certainly is too small for a washing machine. Possibly an addition? Is that the original location for the washing machine?
Will you specify what Yes is a reply to? It is an addition or it is the original location of the washing machine? Where does the pipe connect to? The kitchen?
Does the pipe go through the wall and connect to the kitchen?
The site is prompting the phone call. Not me. Please ignore it if it is not an option. If you fill you kitchen sink then drain it do you hear any glugging from the washing machine drain while the kitchen is draining?
Very good. Will you do the test anyway? Maybe have your assistant drain the sink while you listen at the washing machine drain?
When you did that you filled the kitchen sink first then drained it?
Gotcha. Did you completely fill the kitchen sink then drain it? Were you at the washing machine drain pipe listening when the sink was emptied?
So every drain pipe requires a vent to prevent drain piping from getting air locked. The issue you are having very well may be that the vent is blocked or it would be that the drain pipe is partially blocked. If it is the vent pipe you will want to have a look in the attic. The vent pipe in the attic may run horizontally before it goes out of the roof. Often what will happen is the vent pipe will not be secured very well where it is horizontal. When this happens there will be a belly in the pipe and that belly will fill with rain water and block the vent. Check in the attic to see if the vent pipe is full of water. You will be able to tell by shaking it gently. If you find this then you will want to secure the pipe so that the water in the pipe drains down the pipe and that will solve the issue. If you do not find a pipe in the attic that is full of water then there is a blockage in the drain pipe. In this case then remove the trap and see if the blockage is there. If you do not find a blockage in the trap then the drain pipe will have to be snaked with a drain cleaning machine and possibly inspected with a drain camera.
You are very welcome
