"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."

"Kesa was the best plumber we have had in 5 years. He is respectful and has great personality and shows what caused the problem. If we have problems in the future we will request Kesa first! Rescue Rooter is lucky to have him."

"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

Usually it’s fine to leave a toilet clogged overnight, as long as it’s not close to overflowing. In some cases, the extra time may give the clog time to work itself out. For example, if it’s caused by an excess of toilet paper, letting it sit could result in the clog dissolving and you may be able to simply flush it away by the time you wake up. 

Only let it sit though if you have more than one toilet in the home.

In North America, pipe measurements are listed as the nominal pipe size (NPS). This measurement refers to the outside diameter. As an example, a 1/2-inch copper pipe has an outside diameter of 5/8 of an inch. If a hardware store lists a pipe as having a 2 NPS, it means that all the pipes with this measurement have a 2 ⅜-inch outside diameter, regardless of wall thickness and inside diameter.

Depending on the layout of your bathroom, you may be able to replace a shower valve without removing the tile. The existing hole needs to be large enough to remove your old valve and fit your new valve. If the hole is too small, you’ll need to cut into the wall and remove some of the tile.

Plumber schedules can vary. Many plumbing companies follow a traditional five-day work week, and schedule plumbers so that someone is available during working hours. However, some plumbers choose a four-day work week and take a day off, usually Friday. In these cases, Friday work counts as weekend work and will incur the same extra charges.

Since pedestal sinks are narrow and don’t have a cupboard to conceal pipes, many homeowners change their plumbing to make it less visible. It’s a big reason why installing a pedestal sink is more labor-intensive than other types.
