"Great. Didn't need to cut drywall (this time). Repair was made to fix leaking. Experienced plumber cleaned surrounding area to remount and seal to house siding. It's much better than before! Would hire again to fix all plumbing issues. Great service!"

"I found water on the floor of my basement! Horrors! I got 3 estimates and chose T.QEXCAVATION.Plumbing to do the fix. I liked the work ethic of Terence, the owner who was the guy who did the job. He kept me informed of what was happening and how the project was going, turned the water on when he could and off when he needed to so I had water off and on instead of not which meant the world to me. The job is done, I'm happy with the result and would recommend T.QEXCAVATION.PLUMBING to anyone in need of any kind of plumbing job. He is my plumber from now on."

"I reached out to The Waterline Group (TWG) after getting a quote from one of the large plumbing companies in the area. The problem was a bad Backflow Preventer. The quote was very high and included work that didnâ t need to be done. TWG inspected the problem and got me on the schedule quickly for $900 less than what I was previously quoted. The TWG technicians were very polite and efficient and everything has been working great ever since. TWG exceeded my expectations and they will be my first call the next time I have a plumbing problem."

"Water leak was detected due to uncharacteristically high water bill. Plumber determined leak between mail shutoff valve to water meter. Received several estimates - Interstate was the most competitive - as advertised that’s all they do (water and sewer line repair or replacement). Once hired, professional, courteous, prompt, and skilled. Satisfied so far and would recommend!"

Plumbing questions, answered by experts

Replacing cast iron pipes when they’ve reached the end of their life span is key to preventing leaks and clogs. Over time, cast iron pipes corrode and experience pipe scale, which thickens the inside of the walls and increases the chance of clogs while also decreasing water flow. As the material deteriorates, you could experience costly leaks that increase reparation expenses. 

Cast iron can last between 50 and 75 years, but it’s still a good idea to check for leaks as your pipes approach the 25-year mark, as pipes can already show signs of deterioration within the first three decades.

The standard size of a pipe for the main water line ranges between 3/4 inch to 1 inch in diameter, but ultimately, the size will depend on your household size and its square footage. Depending on the size of the property, the water line size can range upwards to 1.5” in diameter for a very large house nearing 10,000 sq. ft. Incorrect pipe sizing can lead to potential damages and leaks. To avoid incorrect sizing, consider getting help from a local plumbing professional who can help you choose the right size and material for your pipe.

You can use a water gauge to check that water pressure, which should be between 40 and 60 PSI. If you don’t have a water gauge, you can also time how long your showerhead takes to fill up a 1-liter container. If it takes longer than 6 seconds, you’re dealing with a case of low water pressure.

Water main breaks are relatively common, particularly in areas with older infrastructure. The frequency of breaks depends on factors such as the age, material, and size of the water main pipes, weather conditions, and the overall maintenance of the water system. Older cities with outdated pipes are more prone to frequent breaks, while newer communities struggle less with this particular issue.

PVC pipes are more affordable and applicable in most parts of your home’s plumbing system than copper pipes. They also require less maintenance. The only major restriction with PVC pipes is their low heat tolerance. Therefore, they’re not your best option for supplying hot water from the water heater throughout your home. PVC pipes are also larger in diameter, so they may not fit into certain spaces in your home.
