"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!"

Plumbing FAQs, answered by experts

Vinegar is better for an AC drain line because it’s less corrosive and won’t damage the pipes. It’s also a safer and easier product to use. Bleach should not be used on your AC drain line because it can corrode your pipes and harm the evaporator coil in your air conditioner.

A back pressure valve is a control valve used on production vessels, such as separators, treaters, and free water knockouts. The valve holds pressure until a set point is reached, and then releases upstream pressure to reset. Back pressure valves are not safety mechanisms. Instead, they are regulators designed to keep the fluid, gas, or liquid mixture in a system at a certain pressure level to prevent bursts and other incidents.

Meanwhile, a backflow preventer is a safety mechanism that kicks in when the pressure has already failed and contaminated water flows in the reverse direction. Most backflow preventers consist of two one-way valves, or check valves assembled together. This design only allows water to pass through in one direction but not the other.

Yes, you can fill your toilet tank manually to help it flush, or you can pour the water directly into the bowl to flush it manually. This will work for the majority of toilets, as most use a gravity feed system. However, you should only ever use this as a temporary solution. If your toilet tank isn’t filling, you should find out why. First, make sure the speedy valve connected to your toilet and your water main are open. If that doesn’t solve the issue, call in a professional to address the problem.

Shower valve replacement costs an average of $350, and most homeowners pay between $150 and $550. The price will depend on labor costs in your area, as well as the type of diverter valve you choose. A simple diverter valve could cost just $20 in materials, while a high-end mixing valve for better temperature control can cost $350.

You may not be able to prevent water spots on your black faucet, but the good news is that you can quickly wipe away water spots, fingerprints, smudges, and smears with a damp cloth. The best practice is to get in the habit of wiping the black faucet daily to prevent any mineral buildup or hard water stains.
