"Schmitty's Plumbing responded to my Angi's service request almost as soon as I submitted it, and they beat out three other Angi plumbing companies in terms of pricing and transparency. I hired Schmitty's to remove an old double bowl kitchen sink and faucet with a new single bowl sink and upgraded faucet. There was no upselling or attempts to convince us to replace our garbage disposal which two of the other plumbers recommended we do. We saw no reason to replace our disposal which functions well and is not that old. Partners Drake and Gage came out to our home as scheduled, and they got to work immediately working efficiently and thoroughly. We appreciated their no-nonsense, honest, prompt service, and very fair pricing. I chose Schmitty's based on the positive customer reviews, and would hire them again. I told them I would recommend them to all my friends who have plumbing needs!"

"I needed only scope and locate my 4" sewer pipe from an exterior cleanout to the house. Rescue Rooter gave me a discount for the work. John the plumber came out. He has 26 years of experience and was very knowledgeable and skilled at using the camera. I've been doing remodeling for 30 years including plumbing installation (drain pipes, copper water pipe repair and installation). In addition to using the electronic locator, he also went old school in using witching sticks to confirm the location of the pipes."

"Professional, easy to work with, respectful employees, excellent customer service, and quality work! The vanity install required some extra plumbing work and the installer was able to handle it all just fine. Super happy with the work done!"

"They did a great job. Response time was very fast. Our sewer pipe was clogged they cleared it right away, were very professional and gave us a bid to line the sewer pipe to prevent future problems.

Plumbing questions, answered by experts

When evaluating plumbing in Maple Valley, start by locating your main water shut-off valve for emergencies. Next, inspect exposed pipes for freeze protection, as the area experiences occasional hard winter freezes. Schedule a sewer scope inspection to check for root intrusion. If your home has original copper supply lines, inspect them for pitting corrosion. Finally, check your water heater to ensure it meets current state energy efficiency standards.

Helpful?

Cosmetic plumbing in WA involves simple fixture swaps like replacing a faucet or toilet. These updates do not require permits as long as the underlying pipes remain untouched. Functional projects, such as repairing leaks or replacing water heaters, always require permits and a licensed professional. Keep in mind that opening a wall for a cosmetic bathroom update frequently exposes corroded pipes, immediately turning a simple visual upgrade into a functional repair.

Helpful?

For plumbing in Maple Valley, choose materials that handle the soft, acidic local water. This water causes pinhole leaks in older copper pipes. Use PEX tubing for supply lines, as it resists corrosion and withstands occasional winter freezes. For drain and vent lines, select approved PVC or ABS plastic. When running underground exterior pipes in our clay-heavy soils, install a crushed gravel base to prevent settling and protect the lines.

Helpful?

After finishing plumbing in WA, schedule a final inspection before closing any walls. If you disturb older galvanized pipes, test your water quality to check for leached sediment. Submit as-built drawings for any new sewer lateral connections. Finally, inspect your crawlspace vapor barrier for damage. High annual rainfall makes crawlspace moisture a serious issue, so ensure this barrier remains completely intact to protect your home from excess dampness.

Helpful?

Updating your plumbing in Maple Valley directly protects your property value and removes buyer objections. A clean sewer scope report and a compliant, modern water heater are strong assets during resale. Replacing old copper lines with modern materials builds buyer confidence and prevents inspection delays. Always close out your permits after finishing the work. Documented, permitted upgrades prove your system is safe and fully compliant with state disclosure laws.
