"Zach and his crew were amazing! Our old water heater sprung a massive leak at 2:00am on a Saturday morning. Contacted Zach at 7:30am and he called right back and was here within the hour. Not only did we replace our water heater with a tankless model, but also moved it from the second floor to garage. Zach did all of this on a Saturday for a flat fee!! He and his crew were here for 9 hours without complaint or even seeming to take a rest!! Knockout Plumbing is indeed a 'Knockout' and I would highly recommend!! Kudos to all!!"

"Very well done! Tennant called to notify us of a leaking garbage disposal unit. Received a phone call when technician (Raman) arrived with a clear diagnosis before work was to be completed. Used an Angie's list special that was honored with no up-charges or additional work added. Drain Pro is now my go-to for all plumbing needs."

"They were fantastic. Jared and Jake were very professional and courteous. They went above and beyond when replacing our water heater. The previous owners of the house installed the old water heater poorly. These guys not only replaced the water heater, but fixed all the piping and attachments as well. I’d definitely hire this company again for any plumbing issues."

"I can't say enough about how amazing Matt and his team are. He came out initially for a quick inspection to give us an idea what was going on with a leak in our basement and it turned into a nightmare of a situation with so many different problems. Our house is very old and there were a lot of things going wrong all at once. That being said, they handled everything so well and Matt's expertise, professionalism, and compassion meant so much to us during such a stressful time. I will recommend Matt to anyone that ever has a plumbing problem, he truly deserves everyone's business!"

"Jason and Henry crawled  through a very unpleasant 3' space between our first and second floor to find out that there was a double ptrap install and the vent line just venting into open space. They corrected the plumbing, installed a studer cap and brought everything upto code (fixing the bad smell) problem.

I really appreciate there willingness to belly craw into a tight space to solve the problem without having to cut a hole in the celling.

They came in just under what they estimated it to cost. Showed up promptly and were professional. This is the second time I have used Cahill's Plumbing and have always had a good experience.

FAQs for plumbing installation for a remodel or addition projects in Federal Way, WA

Adding bathroom plumbing to a detached garage starts with the basic line installation cost of $900 to $1,300. On top of this base expense, you'll need to budget for each fixture. A toilet costs  $250 to $550, sinks cost $150 to $800, and a shower or bathtub costs $400 to $1,900. The project will also require ventilation, moisture-resistant materials, and possibly electrical work. Remember that these costs reflect only the plumbing aspects—additional construction, finishing, and permitting expenses will apply to complete a functional bathroom space.

While certain aspects of garage renovation might be suitable for DIY enthusiasts, plumbing installation requires professional expertise. Connecting to water and sewer systems demands specialized knowledge and equipment, and improper installation can result in severe water damage, code violations, and potential health hazards. Most municipalities require permits for plumbing modifications, and these often stipulate that licensed professionals must perform work. Consider limiting your involvement to simpler tasks like painting or basic finishing work.

The timeframe for adding plumbing to a detached garage spans one to three days for the actual plumbing work. However, this represents only the active installation period. The complete project timeline must account for planning, obtaining permits (which can take weeks depending on your locality), coordinating multiple contractors if needed, and addressing any unexpected challenges that arise during installation. Weather conditions can also impact excavation and outdoor connection work.

Adding plumbing to a detached garage will likely increase your property taxes. Tax assessors consider plumbing an improvement that enhances property value and functionality. The specific tax impact varies by location and project scope. Converting a garage into living space with plumbing facilities can trigger significant reassessment in many jurisdictions. Before proceeding with your project, consult your local tax assessor's office to understand the potential tax implications and factor this ongoing expense into your decision-making process.
