"Sutherland plumbing recently replaced my homes waterline after we discovered it was leaking. I chose them after getting 3 quotes & am very pleased with the results. Their pricing was competitive and their communication from quote to project completion was extraordinary. By using horizontal drilling they avoided having to remove rose bushes & retaining walls and left the sight clean. They will be my go to plumber going forward."

"Landon was amazing! I contacted Service Plus Plumbing to install a new kitchen faucet that I had purchased as a gift for my mom. First, he responded to my request for quote (through Home Advisor) within 5 minutes...on a Saturday! Landon was so kind and professional. He was able to fix the existing faucet (saving me the cost of the new faucet) and even tidied and tightened all the plumbing under her sink. My mom was very impressed, and that’s not easy to do. My family has several homes in the area and now we have a new plumber. We’ll tell everyone we know to call Service Plus Plumbing for all their plumbing needs."

"There aren't enough superlatives to properly rate this company. My wife and I are Realtors. So we deal with a lot of plumbers, electricians, etc. Axiom is far and away the best in all areas - friendliness, competence, experience, pricing, honesty, promptness - you name it. Our main drain line was clogged. After 3 different plumbers failed to fix the problem, Rob Evans of Axiom PDX found the clog and fixed in less than an hour. Rob saved us thousands of dollars in bogus repairs that had been proposed by the other plumber. Unless I am forced, I will never use or recommend a plumbing services company other than Axiom PDX. You won't be sorry (and you really might be sorry if you run into one of those big company scammers who almost got us)."

"The service was professional and efficient. We had been without hot water for months, all the other plumbers who came in and assessed the job told us they could not help or it was too complicated. Anton just said he liked a challenge and once the project was started it only took a few days. I would recommend Anton to anyone needing plumbing work. Our family is very grateful!"

"I had Henco help with my new home water conditioner installation(pre-brought from Pentair). The job was done super well and the guys(Nolan and Zack) who came out were very professional and willing to explain all the little details about what I needed to know about the system and the plumbing work. I am glad I hired Henco, and I will definitely go back to them if any plumbing job is needed in the future."

Plumbing FAQs, answered by experts

You cannot replace a shower valve without turning off the water. Always turn your water off before doing any kind of plumbing work—and this project is no exception. Turning off the water is a best practice for personal safety and to keep things in your home dry.

Baking soda and vinegar aren’t just great for making a volcano for your kid’s science project. You can also pour this dynamic duo down your shower drain to dissolve hair clogs. If that doesn’t do the trick, you can step it up with a commercial liquid drain cleaner. 

The size of a pipe isn’t always the outside or inside diameter. Rather, it’s a nominal diameter that depends on the type of pipe. For male pipes, you’ll need to measure the outside diameter. For female pipes, you’ll need to measure the inside diameter. You’ll then need to use a nominal diameter conversion chart to get the actual pipe size you’d buy in the store.

Adding another bathroom isn’t the most complicated project you can undertake, but it’s in the top 5%. Anything involving plumbing and electrical work should be handed off to a pro, and adding a half bath involves both. A contractor may charge $70 to $120 an hour for labor, but chances are they can work much faster and more accurately than a DIYer.

No, putting new plumber’s tape over old plumber’s tape is not recommended. The old tape connection may not be completely adhered and could cause a leak. 

Instead, remove the old tape completely, clean off the pipe threads with a clean rag and wire brush if needed, then apply new plumber’s tape to make your connection.
