Common Questions

What's the most common cause of low water pressure in Potomac homes, and how do you fix it?

In our area, low water pressure often stems from mineral buildup in older pipes or fixtures, especially with our local water composition. It can also be caused by hidden leaks or a failing pressure regulator. We start with a thorough plumbing inspection to pinpoint the exact cause, whether it's a faucet aerator needing cleaning, a corroded pipe section requiring repair, or a water heater issue. Our approach is diagnostic first, ensuring we fix the root problem, not just a symptom.

My garbage disposal is leaking. Can you repair it, or is a full replacement usually needed?

It depends on where the leak is originating. Many leaks come from worn seals or loose connections that we can repair efficiently. However, if the leak is from a cracked housing or the unit is very old, a replacement might be the more reliable and cost-effective long-term solution. With over 30 years of experience, we'll give you an honest assessment and a clear quote for either a repair or a new garbage disposal installation, so you can make the best decision for your kitchen.

Do you handle major projects like full sewer line replacements?

Absolutely. From ground dig-ups for new sewer installation to repairing broken lines, major underground work is a core part of our service. My background includes decades as a plumbing supervisor on large-scale projects, so we have the expertise to manage significant replacements or installations efficiently and with minimal disruption to your property. We're fully equipped and insured for this level of work, providing Potomac homeowners and businesses with a reliable local source for these critical jobs.
