 Washing machine seems to cause extremely low water flow
Author: mwbarrett47 (FL)

Hi, I hope someone can lead me in the right direction. Ordinarily the water pressure/water flow in my house is great. A few months ago we noticed that the water was just trickling from any faucet in the house. If you flushed the toilet it would take extremely long for the tank to refill because of this low flow. We did some investigating and seem to think we have it narrowed down to when the washing machine is running. For example, if we turn the washing machine off, then the water flow is back to normal. If we turn the washer back on, it trickles out from any faucet in the house. This doesn't make any sense to me. The clothes in the washer are wet so it is getting water. Is it getting enough water, who knows?

The washing machine is a LG model WM2701HV which was purchased new in July 2010.

You have a volume issue, which is usually a restriction in the main water line. A clogged screen in the pressure reducing valve or a clogged water filter are 2 common causes.

Many washing machine hoses have hose washeres with screens to prevent debris from entering the machine. Check for this washer on both ends of the hot and cold hoses.

Your issue is not the washing machine. You have a volume/pressure. I would verify everything from the main shut off to each water appliance. As asked, do you have a pressure valve on the outside of your water service line?

Best Wishes

Thanks for the reply. I don't really know if I have a pressure valve on the outside of my water service line. I don't see one anywhere near where the water line enters my house. I don't really see one near the water meter either. I guess there could be one but I am not sure that I would know one when I saw it or perhaps I just didn't do enough digging. What about the plumbing stacks that come thru the roof to provide air flow? Could a partial clog in one of them cause low water flow? What about the hot water heater? I know I am just throwing stuff against the wall here to see if anything sticks. I have a call into a plumber so hopefully he is competent enough to figure it out. I will post the results when the problem is finally resolved. I just hope it turns out to be something simple. Maybe I do have a pressure valve and that is the problem as most of you suspect. We shall see.
