"The technician arrived at the start of the 2 hour window. On time! Very professional. Explained options for dealing with my toilet leak. I chose to replace the toilet and gave him guidlines for the new toilet. He went to Home Depot, acquired the toilet returned promptly and installed it in a timely manner. After which he broke down and explained the itemized charges. After paying for the work thru my credit card, I received an e-mail summary right away...One major concern that I had in hiring Western Rooter & Plumbing was that their technicians had been vaccinated for Covid 19. I had been referred to Western earlier this year by my condo HOA for a common area leak repair in my unit. I was assured by the dispatcher that the technician coming to my condo was vaccinated against Covid. So when I had this toilet leak problem 6 months later that I had to pay for, out of a multitude of plumbing companies, I went back to Western Rooter & Plumbing after receiving the same assurance."

"The technician was early, polite, and efficient. The price was fair and the work fixed the problem. He did offer to run a camera down the drain line, but every plumber I've ever hired has done that and he didn't force the issue. An all-around terrific experience."

Sewer Boyz are our GO-TO for all things plumbing-related. We have had them work on basic leak repairs, to installing new toilets, to Hydrojetting blocked drainage lines, to replacing sump pumps! They are super professional and knowledgeable and above that, very easy to work with. If it's a more complex repair, they always make sure you understand exactly what the issue is before you make any commitments. We trust and appreciate Jonathan and in this line of business, we NEED to have knowledgable, dependable and affordable specialists like Jonathan and his team. It makes our jobs and lives easier."

Toilets FAQs, answered by experts

Yes, you should screw your flange to the subfloor, including cement. The best way to get this done is to predrill holes into the concrete using a hammer drill and a ¼-inch concrete bit. Be careful when you’re ready to bolt your flange down, as you can accidentally crack it. You can avoid this issue by not installing the screws too deep. Or, you can opt for a flange with a stainless steel ring so you don’t have to worry about cracking the plastic.

There are a few reasons why this could be the case. More than likely, your flapper is worn out and needs to be replaced. When it’s worn out, it lowers the water pressure during each flush leading to inefficient flushing. Luckily, replacing a toilet flapper is a simple repair that should only take about 30 minutes.

DIY is not recommended for commercial settings due to safety and code compliance. Hire licensed professionals.

The cost of making a bathroom accessible can be $3,000 to $25,000, but you could spend as much as $50,000 building a brand-new ADA-compliant bathroom. Some bathroom accessibility upgrades to consider include:

  • Installing grab bars: $100–$500 

  • Lowering cabinets and vanities: $1,200–$2,500

  • Installing modified doors: $700–$1,500

  • Installing a modified toilet: $400–$1,000

  • Installing an accessible sink and faucet: $100–$1,000

  • Adding a walk-in tub: $1,100–$17,000

  • Converting a bathtub into a walk-in tub: $350–$1,000

  • Installing a wheelchair-accessible shower: $2,000–$7,500

  • Installing a shower ramp: $16–$300

Yes, frozen pipes can prevent a toilet from working correctly. If the pipes are frozen, water cannot flow, which means your toilet tank won't be able to refill after a flush. This will prevent the toilet from flushing again. Depending on which lines are frozen, the ice can also block the drain pipe, preventing water from flushing away.

As a temporary workaround, you can manually add water to the tank for each flush. To clear a frozen drain pipe, you can try filling the toilet bowl or tank with warm water and flushing to help thaw the ice. However, the best long-term solution is to unfreeze the pipes to get your toilet back in working order.
