Leak Detection Equipment We Use

leak detection equipment we use

Detecting plumbing leaks can be a challenge because your home’s plumbing is often buried in concrete slab foundations and sealed in the walls.

If the source of a water or sewer leak is not obvious, you will want to contact an experienced leak detection company.

Trained technicians and specialized leak detection equipment can quickly find the leak source and repair it as soon as possible.

The good news is that today’s plumbing leak detection companies and equipment can avoid tearing up floors, or tearing down walls or ceilings to find the source of the leak and fix it.

We use several different types of leak detection equipment, including:

Video inspection that can see into the pipes by sending a camera down the pipes to find the location and cause of a leak.

Ultrasonic detection that uses sound technology to measure sound loss variations in the pipes.

Infrared leak detection that allows plumbers to see what is inside walls, beneath your floors, and underground the piping under ground.

Smoke detection in which harmless smoke is pumped into the pipes to emerge where a pipe leaks.

What are the common symptoms of leaky plumbing?

  • Cracks or wet spots appearing in your walls, floors, or ceilings.
  • Warm spots on the floor where hot water is leaking underneath.
  • Mildew or unusual moisture under carpets.
  • Hearing running water when all the fixtures in your home are turned off.
  • Nasty smells coming from floors or walls near drains or sewer piping.
  • Shifting or cracking of your foundation/slab.

Signs that you may have a water main leak include:

Decreased water pressure: Rust, scaling, and mineral deposits can build up inside and narrow your water main pipe significantly.

Increased water usage & bill: Periodically check the water usage in your home to see if there’s a sudden and unexplained spike in water use and water bill. A spike is often a sign of a new leak going unnoticed.

With a smaller and slow leak in the underground water main, damage may go undetected for months or years until it becomes too large to repair inexpensively.

Soggy areas in your yard: Areas in your yard of unusual vegetation growth, wet or sinking ground. With a large enough water main leak, the water shows up on the ground’s surface around your home. Squishy, muddy areas that aren’t caused by faulty sprinklers are likely coming from underground.

Unchecked, underground water main leaks can damage landscaping and your home’s foundation, adding repair costs. It’s better to detect leaks and fix or replace the water main early.

Fouled water coming into your home: Traces of rust or dirtier water coming from your faucets likely come from a deteriorating or split water main.

Dave & Junior did a fantastic job, and under less-than-ideal circumstances with regards to the digging to expose the elbow that leaked! They found it, fixed it, refilled the pit, and cleaned up afterwards in good order.

Would HIGHLY recommend this team anyone who needs a difficult job WELL DONE!

Kyle was fantastic. He identified the problem and explained everything to us in terms. Our options and he recommended the less expensive option, because it makes the most sense and is less intrusive. Note: Kyle spoke to us and not at us.

He then recommended Dry County Restoration to repair all of the damage from the broken pipe. Steve is amazing! He had fans out here for the flooding 20 minutes after we signed the contract. Again, he spoke to us and not at us.

Showed us where all the flooding was and why things needed to be replaced. He used some sort of electric tool thingy. Both companies are amazing. Local, family and veteran owned. You can’t beat that.

The guys did a great job with fixing my toilet and checked out why my dishwasher was leaking.

Will definitely call your company back when I need repairs in the future. When I called to make an appointment for repairs you came out the following day, which is awesome cause most places I called I had to wait a few days or more. I really appreciate the quick service.

I could not have asked for a more professional service. We had a below slab leak that we caught early. RTOP was able to get on the calendar as second plumber evaluation. Kyle, was the service tech to respond.

As a retired contractor and firefighter i have seen both ends of contracting and public service. Kyle knocked it out of the park from his first evaluation. We were expecting a 10k dollar plus repipe, and worried of how to absorb this hit. Kyle was able to reassure us he could find and stop the leak. Typically i would have blown that response off and went with another. He showed great humility, experienced knowledge and didnt go over the top.

Within an hour he was able to pinpoint the leak and stop it. As well as express the various types of repair’s . Because of the available money at hand and with his exceptional knowledge and reassurance we went with a pipping reroute.

Kyle nailed it. Perfect craftsmanship and attention to detail and homeowners concerns. RT Olson may have a new candidate for ownership. Thank you young man. Excellent job.

A pipe busted and our garage and outside yard area flooded.

David and Junior (JR) were very communicative, shared their best plumbing practices and advice, and answered all of our questions! When they didn’t have an answer, they immediately connected with their boss to find the best solution or answer.

They were responsive, friendly, and professional, we will definitely do business with them in the future, if needed!

David and Jr. were the definition of accurate and awesome! Two really personable guys that came in and handled business with no delay. They performed the leak detection and put me in contact with RT Olsens sister restoration company instantly. I am thoroughly satisfied! Can’t wait for the repair. Thanks again RT Olsen as well as David & Jr.

We recently had a slab leak that ruined our flooring and lower kitchen cabinets. Bob Olson from RT Olson Plumbing quickly identified the source of the problem. Because we had a couple other slab leaks in the past, Bob recommended a whole-house re-pipe. Bob worked with Stephen Gimenez at Dry County Restoration and together, their crews took care of all of the problems caused by the water damage. Bob told us that our insurance should cover new flooring and kitchen cabinets, but our insurance company repeatedly tried to deny our claim.

Bob and Stephen advocated MANY TIMES on our behalf with our insurance adjuster, and if it hadn’t been for their knowledge about valid claims, our insurance company would have paid us ZERO. Instead, thanks to Bob and Stephen, our insurance company finally agreed to replace the flooring and the kitchen cabinets. In our case, this was over a $25,000 difference. Dry County Restoration completed the work, and the house looks beautiful!

We are so thankful to RT Olson Plumbing and Dry County Restoration. Thank you all so much! Sharon Bishop

Technicians Dave and Junior at RT Olson Plumbing did an excellent job of determining the source of the water leak from my street drain, quoted me a reasonable price to repair, then completed the repair in good time.

I stayed to watch the detection process and was pleased that Dave showed a lot of knowledge and explained exactly what he was doing to detect where the leak was. After finding the source (an out-of-view valve in a valve box), Dave cleared the dirt from all 11 valves in the manifold, so any additional valves leaks would be evident, then replaced the bad valve.

These guys were friendly, knowledgeable and I’d recommend them for any plumbing job.

Two words no one wants to hear – slab leak.

Had a slab leak, carpet saturated, dry wall wet, space behind fireplace wet and the plumber sent out by home warranty company COMPLETELY INEPT.

Had used RT Olson in the past and called Bob when it was clear we were going to have to get our homeowners insurance involved. Bob sent someone out immediately gave us a quote that was within industry norms and the insurance company approved it.

Three hours after beginning…. water restored to the house after 5 days without water, plumbing rerouted and pressure guage so that hopefully same problem would not occur again. So here is what YOU need to know.

If you have a leak – don’t wonder, think or consider about it – Call RT Olson because because they will fix it right the first time. Best plumbers around!! Thanks again!!!!

I had a slab leak in my home and RT Olson Plumbing promptly came out to my home where they found the leak very quickly and capped the line.

They later redirected the pipe to restore my water. I was very impressed with the quality & prompt service both at my home and when I called their office.

Hot side slab leak- words that I used to fear would empty my wallet.

RT Olson not only gave me the most competitive quote, they had actually convince AAA to pay for the plumbing.

They were able to fix it quickly and help with the clean up. $0 out of my pocket makes me a happy man. Thanks for being awesome.

As a busy mom with 5 kids, I was very overwhelmed with the stress of having a water leak but Bob was very patient with me and answered all of my questions.

His team came and quickly worked to get us back into our home. They were friendly and did amazing work. I am very thankful for Bob and his team.

What set Bob apart from the rest is as rocky as we started it out, he was very humble and honest and he really had my families best interest at heart and I am very grateful. Thank you.

I had a water leak but I didn’t know where it was coming from, called a different plumber before calling Bob. I saw a big difference between Bob and the other plumber.

Bob was able to come in on time, explain to me the issue and roughly how much it would cost in 2 cases and also explained to me the insurance process and what to do when it came to talking to you them. He came in the next day detecting where exactly the issue was, and told me straight up how much it would cost if he gets started on it.

The price was reasonable and I am very satisfied with the process. If I could give them more than 5 stars I would. I highly recommend them to everyone!!!!

RT Olson staff were professional and friendly. They explained in detail how they were going to fix the slab leak and what the challenges were that they would face.

They were prompt, efficient and cleaned up after they’re work was finished. At first there was a problem with the pressure regulator. They came back immediately and fixed it. I was without hot water for six weeks. RT Olson fixed it in two days!

Clean, fast and great quality work.

Great price, and patient service. The plumber that came was on time, even stayed until the city came to fix the main shut of valve that I found leaking when I got home which took a couple of hours.

If you want quality work, go with them. It’s worth every penny. Would highly recommend.

Bob Olson and his guys did exactly what I was looking for, came early, found the leak in my wall super fast and found the problem to be very minimal, total cost was half what I expected. Even had them replace a stuck hose bib before they left.

Guys were professional, communication was quick, if needed I’ll use RT in the future for sure. Thanks!

I had a main line water leak in the middle of the night. I contacted R T Olson plumbing first thing in the morning and they were very helpful from the minute I talked to them. Had a plumber out within 30 mins and fixed my problem in only a few hours.

I felt very comfortable with this company and didn’t feel like I was getting ripped off. They let me know step by step what they were doing and were very respectful.

Will definitely be calling them for any plumbing issues in the future. Thanks again.

The repairs we hired the plumber were fixed. However, other repair items developed. We need a referral to a leak detection company and a referral to company that can air high-pressure clean patio drains around the pool.

The contractor was more than prompt; the contractor was early for the appointment. The representative was cordial, professional, and responsive. The representative’s work was done well and on budget. Thank you.
