"They weren't able address part of my project which included fixing a bulkhead wall, and masonry. I wanted to have it all addressed project by project and discovered that there was more damage to one of the walls that needed fixing. As they weren't concrete 'masons', they wouldn't be able to fully address that before installing a drainage system. It was all within my budget. I just didn't want to have the drainage system installed and have it fail because due to the mortar crumbling. The person that went to my house spent a considerable amount of time. He was knowledgeable, courteous, and not pushy. It wasn't until I had another contractor come through that I realized that what I had initially planned on was not going to work. When I went to cancel, the person that handled my estimate was concerned that I was cancelling and that I was being given "bad advice" from another contractor. I thanked him for the time he spent, and the information that he gave me, and sent my cancellation form. I would have hired them had they been able to fully address the entire project(s)."

"Bill was great to work with! He did such a great job. He was very honest and had great ideas. He was extremely professional and kept to his word. He showed up on time and completed the project in a timely manner. His prices are reasonable and fair. I have several future projects lined up with Blake Mountain Home Improvement. I can't say enough great things about Blake Mountain. As a matter of fact I still talk to him!!"

Plumbing FAQs, answered by experts

Start by inspecting visible pipes for signs of corrosion, moisture, or discoloration, which can indicate a leak. You should also listen for sounds like hissing or dripping, which may point you toward a leak. Moisture meters and infrared cameras can also help you identify areas of increased moisture around your home, which can also signify a leak.

The size of a pipe isn’t always the outside or inside diameter. Rather, it’s a nominal diameter that depends on the type of pipe. For male pipes, you’ll need to measure the outside diameter. For female pipes, you’ll need to measure the inside diameter. You’ll then need to use a nominal diameter conversion chart to get the actual pipe size you’d buy in the store.

If your toilet won’t stop running, you might have a bad fill valve. This may be the case if the valve has calcium or debris buildup, is cracked, or shows visible signs of wear and tear. A bad fill valve may also be the culprit if you’ve already checked the flapper and chain and adjusted the fill height to no avail.

You’ll only need to replace your sink’s pipes when you start to notice signs of wear like corrosion or leaking. Most pipes last somewhere between 20 and 100 years, depending on the material. Copper and cast iron can last up to 100 years. Galvanized steel and brass generally have a 50-year lifespan. PVC pipes last 25 to 40 years.

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.
