Top Questions Homeowners Ask Plumbers (And the Answers You Actually Need)

If you’re dealing with a plumbing issue in your home, chances are you’ve typed something like “Seattle plumber near me”, “why is my water heater not working”, or “who fixes clogged drains fast” into Google. At Knockout Plumbing & Mechanical, we get calls every day with these same questions — so we put together this guide to answer them clearly, honestly, and helpfully.

Whether you’re searching for emergency plumbing services, affordable sewer repair in Seattle, or need help figuring out if it’s time to replace your water heater, we’ve got you covered.

💬 Common Plumbing Questions

1. Why is my water heater not getting hot?

This is one of the most common water heater repair calls we get in Seattle. It could be a faulty thermostat, sediment buildup, or a failed heating element. We specialize in both tankless water heater repair and traditional gas water heater service — and can often fix the issue the same day.

2. Do I need to replace my sewer line?

If you’re noticing recurring clogs, bad odors, or soggy spots in your yard, it could be time for a sewer inspection with camera. We offer sewer line repair and replacement throughout Seattle, Everett, Renton, and the surrounding areas.


3. Why is my toilet constantly running or leaking?

Leaking toilets are a huge source of wasted water. Sometimes it’s a simple flapper fix; other times, we recommend a full toilet rebuild. We provide toilet repair, replacement, and installation services for both residential and commercial properties.


4. How do I know if I have a hidden leak?

If you’re seeing water damage, spikes in your water bill, or hearing water running when everything is off — you might need leak detection services. Our licensed plumbers use modern tools to find and fix leaks fast.


5. What plumbing upgrades should I do during a remodel?

Whether you’re doing a kitchen remodel, bathroom renovation, or building an ADU in Seattle, we provide rough-ins, fixture relocation, and full repiping services. We’ll help you plan plumbing upgrades that fit your budget and timeline.
