What Is Leak Detection and how Thomas Plumbers can help you.

Leak detection is a control method used to identify, monitor, and measure the unintentional entry or escape of fluids and gases, usually from pressurized systems or into empty enclosures. Leaks can move from the inside of a component or machine into the outside, or penetrate from the outside in, due to differences in pressure between two regions. Most leak detectors are primarily responsible for locating the leak, determining the extent or rate of leakage, and keeping track of increases or decreases in leakage. Leak detection is highly important in industrial systems that rely on sensitive components or equipment with the potential for being damaged by external contaminants. 

Environmental concerns and the rising value of some manufactured products have made leak management a vital concern. A product’s quality and the safety level involved in its production can be greatly influenced by leak detection effectiveness. Leak detectors often reduce overall manufacturing costs by decreasing the need for repairing or reworking products. Leak testing and detection are implemented to prevent material or energy loss, improve a manufacturing system’s reliability, and reduce the risk of environmental contamination. 

Leak Detection Terminology

In order to understand the principles of leak detection methods, it is necessary become familiar with the terms used in the process. A leak itself is defined as the passage through which a gas or fluid escapes, leakage refers to the fluid escaping, and leak rate is the amount of fluid or gas passing through the leak over a unit of time and under a specific set of conditions. The minimum detectable leak is the smallest passage or flaw that can be detected in a leaking system, while the minimum detectable leak rate is the lowest rate of escape that can be identified and measured. Minimum detection levels are used to determine the sensitivity of a leak detector, but these values are often influenced by variables such as operating pressure and temperature.

Types of Leaks

There are generally two types of leaks that can occur in an industrial setting. A “real leak” is a localized source of outflow, such as a simple hole, that provides a direct passage through which material escapes. A real leak can be in the form of a crack, a tube, or a flawed opening. These kinds of leaks often expand over time and they may change due to fluctuations in temperature and pressure. A distributed leak is a specific type of real leak caused by fluid permeating an extended barrier, which involves the diffusion of fluid particles through a porous solid. A “virtual leak” is the second basic type of industrial leak, and it occurs due to the gradual desorption of gas from a surface or gas escaping from sealed containers in a vacuum system. Vacuum systems sometimes have both real and virtual leaks occurring at the same time.

Selecting a Leak Detection Method

There are several factors that may influence a leak detector’s effectiveness for a given application. Some of the major considerations in selecting a leak detection method include the size of the potential leak, the physical specifications of the system, the type of tracer fluid being used, and the purpose of the detection device (whether it is intended to detect, locate, or measure). These factors can affect leak detector selections in a number of ways:

  • Large Leaks: If the leakage amount is too large, the leak detector can malfunction, making it important for the instrument and detection method to have a working range suitable for the problem. When a detector moves to full scale and cannot be reset unless it is removed from the leak, it has probably become swamped from excess leakage.


  • Small Leaks: A smaller-sized leak may not register on a detection device because it is below the instrument’s operational range, making it difficult to find and repair. If a detector records zero leakage, this does not necessarily mean there is no leakage present, as the reading may be inaccurate due to the leak’s size. The parameters for a detection device should be determined according to minimum detectable leakage and maximum leak rate.


  • System and Tracer-Fluid Features: If a gas or liquid tracer-fluid is used to track the movement of material, it is important for the tracer to be non-reactive to the system’s components so that it does not interfere with operational performance. Gases with a small molecular size and a high diffusion rate, such as helium, tend to be effective in these circumstances.


  • Leak Location: If the purpose of the detection unit is to locate and pinpoint a leak, probes or portable detectors may be needed to scan the surface of the fluid passage. In vacuum systems, a tracer fluid can be effective for spotting the position of a leak, while pressure systems may be better served by bubble detectors, liquid penetrators, and chemical indicators.

Bathroom renovations 

can have a significant impact on the way people use and view their homes. A clean, beautiful space can make homeowners’ daily routines that much more pleasant and potentially add value to the house. But, regardless of the numerous benefits a bathroom remodeling project holds, it’s a big job and should be thought about seriously.

As plumbing renovation experts we explain the reasons why people get bathroom renovations usually fall into three categories. People may either need a bathroom that functions differently, one that’s more modern and stylish, or a bathroom that’s clean and undamaged.

If you’re considering a bathroom renovation in your own home, it may be smart to look at

the reasons other people begin this significant home remodeling project. It may even give you new bathroom renovation ideas!

1. Functional improvement 

Thomas Plumbers explain that as people grow older, different shower options become more appealing because of their safety. When a home has multiple bathtubs, she said that people often choose to turn one into a large shower. As well as being luxurious and looking great, turning a former bathtub into a walk-in shower eliminates a significant slipping hazard – stepping over the tub’s curb.

Showers can be installed that have minimal or no curbs, which are easier to step over and look modern. Seats and handles in the shower, lower sinks and other functional modifications that make the bathroom more friendly to people with limited mobility are also popular in bathroom makeovers for a stylish appeal.

2. In need of repair 

Some bathrooms simply need a renovation. It’s not just the dirt and grime that can build up in a well-used bathroom – there is often structural damage that leads to bigger problems down the road. Cracked floor tiles, excessive mold or water damage to the ceiling below the shower may be signs of leaks or problems which require more than surface repair.

Although fixing broken fixtures or mending damage may be a popular reason for a bathroom renovation, for some it may be an excuse to finally create the bathroom they’ve always wanted as well.

3. Update the look 

Modernizing or improving the look of the bathroom is one of the most popular reasons for a bathroom remodeling. Sometimes people get tired of the bright blue fixtures that were there when they moved in, while other times people just want more use of the space. They want to update the space to include more storage or larger fixtures.

We at Thomas Plumbers always advises our clients to look to the future to decide whether they want to renovate their bathroom and how they should do it.

“We always ask people to consider how long they’re planning to stay in the home. If they are planning to grow old in the home, to make sure that they make it age appropriate and something they can grow into. So they don’t say, ‘Why did we keep this tub?'”

These popular reasons for making over your bathroom may help you decide whether or not it’s time to update your space.


All About Taps & Mixers

Thomas Plumbers are experts at the right choice of Home aesthetics. Faucets are the most noticeable facets of your plumbing. They are where form and design meet function. Choosing the type of faucet for your home, one with superior design and function, is an important decision for any homeowner. There are many options out there for the consumer to choose from, many of them sporting new and innovative design and functionality. Some of these faucets include:

  • Single handle
  • Top mount
  • Side mount handles
  • Pull out spout
  • Handle-less faucets with motion sensors

They also come in a variety of finishes from brass and brushed nickel to chrome.

Faucet Innovations

Faucets have changed a lot in the past ten years. Most modern faucets no longer contain washers, but use a self contained cartridge to stop leaks. While these new faucets are often sturdier than the old models, when they do break or leak, they become much more difficult to repair and/or replace. This is because cartridges are specific to the brand and style of faucet installed. 

What is hydrojetting?

Hydrojetting is the process of using a high-pressured flow of water to scour the interior surfaces of the plumbing pipes, removing scale, grease and other debris that's built up inside the pipe walls over time. As opposed to rodding, where a plumber uses a tool to power a hole through the buildup, hydrojetting achieves a comprehensive cleaning of the pipes.


An inside look at how it works


Accessing a cleanout, an area of the plumbing system that allows a specialist to easily gain access to the pipes, the plumber inserts a hose that's connected to a tank of water. The hose can withstand the high-pressured water that's sent into the pipes, and a specialized machine pressurizes water from the tank.

The plumber should have the expertise to deliver the right water pressure for the problem at hand, which varies depending on the condition of the pipes. In general, a plumber may pressurize the water up to a 5,000 psi, or more, and deliver as many as 20 gallons of water per minute.

The process of removing buildup involves working with gravity. The majority of home plumbing systems use gravity to pull wastewater out of the home and into the local sewer system. The hydrojetting tool works from the bottom up. Inserted into the downstream portion of the system, it moves upstream, working its way up through the system. As the water scours the pipes, the debris that's dislodged then moves down, with gravity, safely flushing the debris out of the system.

Getting the job done

The process of hydrojetting works to resolve a number of common plumbing problems. It successfully removes debris that accumulates in the home's plumbing pipes due to hair, soap residue, grease and more. In addition, it resolves tree root infiltration and mineral and scale buildup in the sewer drains.


In most cases, hydrojetting is a safe way to remove blockages that cause clogging. However, it is possible to cause further problems if a novice plumber employs hydrojetting in the sewer lines when tree-root penetration is significant.

Always work with a plumber who will visually inspect the indoor plumbing system and the sewer lines using video camera equipment to assess the root of the problem before implementing any solution. If tree root infiltration has led to pipe damage or compromised the pipe's waterproof coating, hydrojetting will not solve the problem, and can even lead to more problems, such as causing infiltration of rocks and soil through perforated septic lines.

The plumber should also use video inspection after cleaning out plumbing pipes to assess the effectiveness of the hydrojetting, and the general condition of the pipes.

If you're experiencing problems with your plumbing system, work with an experienced, knowledgeable plumbing specialist. Using diagnostic tools, hydrojetting allows plumbers to accurately and effectively clean out debris from the plumbing system and sewer lines.
