What should I consider when installing a sewer backflow preventer?

• <div><p>Be sure to consider how often you may need access to your pipes in the future. This can help you decide if you want to install a basic PVC backflow preventer or spring for a clear or removable one. </p><p>If you think you’ll need access to your plumbing often, or if your pipes have a history of problems, it’s probably worth spending a little more for something you can look into without removing the backwater preventer.</p></div>

Q: How do you adjust the mixing valve on a shower?

• <div><p>You can adjust the mixing valve on your shower if it uses a single handle to control both hot and cold water by removing the handle and adjusting the cap on the mixing valve. The cap fits over the valve handle and creates a low and high point for your handle to spin. Remove the cap and turn it to adjust how it mixes hot and cold water, and then replace the cap and reinstall the handle.</p></div>

Q: What is the air admittance valve on a washer drain?

• <div><p>The air admittance valve, or AAV, is a spring-loaded mini-vent that sits right next to your washer. It acts in place of a standard vent stack connection, opening to let air into the drain whenever pressure builds up. It otherwise stays closed to prevent sewer gas from escaping into your home. This gives the washer&rsquo;s plumbing system the air it needs when water enters or drains.</p></div>

Q: Can I remove a bathtub myself?

• <div><p>Yes, you can remove a bathtub yourself if you have previous DIY experience and basic plumbing knowledge. You should have at least one other person help you if you approach this project as a DIY. However, hiring a plumber or bathroom remodeling pro can prevent accidental damage from demolition or water leakage.</p></div>

Q: What’s wrong with high water pressure?

• <div><p>Excessive pressure (above 80 psi) puts too much stress on plumbing pipes, joints, and fixtures. This can lead to leaks and burst pipes. Plus, it shortens the lifespan of appliances, can waste water, and can raise your utility bills. High water pressure might feel like a gift, but it&rsquo;s actually a silent threat to plumbing. </p></div>

Excellent!! He came right out (on Saturday night!!) and assessed the issue. Thankfully, it wasn't a busted pipe, but a very slow draining issue that was backing up into the basement. He referred me to a person who handles this type of problem. I'm really impressed (and super thankful!!) with...
