You may remember from one of our blogs a week or so ago in which Twin Plumbing experts suggested several drain cleaning and maintenance tips for Los Angeles homeowners. One of those tips was to make sure that your home’s main drain has an operational back-flow valve in order to prevent drain disasters in the case of heavy rain and flooding.

We want to dig into that piece of advice a bit more by discussing what a back-flow valve is, exactly, and why it’s so important to have one.

First of all, what is the main drain?

In any home’s sewer system, there’s a main sewage line that is responsible for carrying all of the home’s sewage away from the home and out to the public sewer system. All of your plumbing fixtures drain into the main drain: your shower, your toilet, your area drains, your dishwasher — everything up to and including the kitchen sink flushes wastewater out through this drain.

That’s why it’s so immensely important that you take care care of your main drain! A problem in the main sewer line could cause trouble for all of your home’s plumbing devices.

What does a back-flow valve do?

Your pipes have to handle a great deal of wastewater on any given day — and a rainstorm is frequently all that it takes to push them over the edge. When your drains are sending too much water to the public lines at once, it can reverse, causing all of that wastewater to come rushing back into your home.

A back-flow valve stops that dirty water right in its tracks. When your main drain has a back-flow valve attached, it doesn’t let that sewage go anywhere but out. This is precisely why a back-flow valve should be installed in every home! It’s a precaution against the disasters that cause property damage and health risks.

So call a professional about having a back-flow valve installed for your home today. We hope this blog has been helpful, and as always, thanks for reading!
