"Ned with Mast Plumbing has been great to work with. I?ve hired him for work at my house, which involved relocating the plumbing for my washing machine, extending and repairing some water and drain lines. Ned has also helped several of my friends and some of my clients I?ve referred to him with projects ranging from plumbing new gas lines, tankless water heater installs and installing new water mains. Ned is clearly very experienced, professional and patient. He explains the process clearly, and is honest about your best options. I highly recommend Ned with Mast Plumbing, and will continue to refer him to anyone I find in need of a quality plumber."

"Our service tech, Devan, arrived promptly for an after hours call. He was courteous, professional, and knowledgeable. Showed us exactly where our blockage was and remedied it for a very reasonable price. Having many horrible experiences with plumbers in the last 40 years, I feel like I've finally got a go-to plumber with All About Rooter, LLC ."

"Harts dispatch kept me updated on the status of the plumbers arrival. We called for two issues and of course the mystery noise stopped the day he came! But he was able to fix the low pressure in the sink by replacing the faucet. All other plumbing companies we had out said our only option was to replace the old galvanized pipes! I truly appreciate that Konner took the time to look at the issue, listen to us and come up with a solution that worked and not just say the most expensive option of replacing all the pipes! Highly recommend using Harts!"

"Bath Conversion owner Kevin visited me and listened patiently what I wanted. I wanted to replace the bathtub for the soaked one and add to the shower. Total cost was fair. Once he had a tub, he contacted me then they worked so hard, had almost done in one day. The second day was just finishing and took less than one hour. They cleaned everything. They were very friendly and very professional. I strongly recommend this company to others. Thank you, Kevin."

"I had called out 4 different companies to come and give us an estimate. West Coast Plumbing was the 4th and final one to come out. I had kinda resigned to the fact that we were just going to some how borrow the money to get the water main fixed. The City of course says it needs to be done within 30 days of some kind of leak being noticed by us the homeowner. Our water bill jumped up by $600.00 Long story short, John from West Coast Plumbing came out to take a look. John not only thoroughly took a look at what we already dug out , but told us he can't say for sure until he can get a better look. John said the first thing that needed to be done was have 811 out and to mark all the lines so nothing gets accidentally hit while the digging is going on. He said he would proceed to write me up a estimate that covered the minimal to the worse case scenario. It was very detailed and answered all of my questions. I decided to go with West Coast Plumbing. Not only was John very knowledgeable, but professional and friendly. He was also the only one that said 811 needed to be out before anything could be done. It was better to be safe than sorry. John called 811 and they were all here and done the same day. I was not charged for the trip out by John, it was a free estimate. I was told by another company it was a free estimate and then charged $150.00. I just can't say enough about John and West Coast Plumbing. Michelle who initially set the appointment up was also very helpful and very nice. We also got a Military discount. Thank you for making this experience less stressful. Cynthia M Orting, Washington"

Plumbing FAQs, answered by experts

How long it takes for a pipe to freeze depends on the outdoor temperature, the level of preventative measures taken, and how long the outdoor temperature stays below freezing. With this in mind, expect most pipes to freeze within six to eight hours. Uninsulated exterior pipes can freeze in under six hours if the temperature is below 20 degrees. It takes at least 12 hours for unprotected pipes to freeze at 32 degrees.

Yes, you can have a toilet without a septic tank. However, it will have to be a composting toilet. Composting toilets work similarly to aerobic septic systems in that the waste, which sits in a separate compartment below the toilet itself, is slowly broken down by aerobic bacteria. These toilets typically have a vent to get rid of harmful gasses with a fan, which requires a battery. You will have to dispose of waste in the toilet manually every three weeks to every three months, depending on how many people are using the toilet.

Even though they’re modern-looking, easier to clean, can be hung at any height, and help save space compared to traditional toilets, wall-hung toilets have some downsides. They’re more expensive than standard toilets, sometimes by a few hundred dollars. They’re also difficult to install and may require major plumbing work to reroute the drain if the previous toilet was a floor-mount model.

This tight fit can make repairs more difficult. You’ll also have to consider where you can hang them and weight limit restrictions, so they may not be the best fit for every home.

For a fully-foamed hot tub, freezing typically occurs when the temperature drops below 28 degrees Fahrenheit and remains at or below this level continuously for a minimum of 36 hours. If your hot tub and pumps are still operational, however, the water circulates, and this continuous movement helps prevent freezing, even in very cold conditions. This circulation, along with the insulation provided by the foam, helps maintain the water temperature and prevent it from freezing during extended cold periods. Still, if you’re not planning to run it regularly, be sure to winterize the hot tub properly to prevent damage from freezing.

The best place for a kitchen sink drain is the middle of the sink. Most people prefer center drains because they allow for better water and waste drainage, and the center location limits splashing because water flows straight down the drain hole. If the sink drain is too close to the edge of the sink, water can collect and drain too slowly. It can also be easier to clean sinks when the drain is closer to the center since debris is easier to wash down and doesn’t collect along the sides as easily.
