However, there are also times when a plumber comes out to do any kind of work, like a leaky faucet, and independently decides to run a pressure check. If the pressure is 80 psi or higher, he goes to the homeowner and recommends having the valve installed (which he, of course, is happy to do).

That is the question we started getting and are getting more and more often. And it’s usually from someone involved in a the sale of a house.

Gas valves are integral to the oil and gas industry, enabling the controlled flow of materials through pipelines. Understanding the various valve types and their applications is essential for ensuring the safety, efficiency, and success of operations within this critical sector.

We learned two things. One, most of the manufacturers had no idea what we were even talking about when we asked about the the pressure reducing valve. So how can these valves be that important if the manufacturers have never even heard of it?

It costs about $1,000 to $1,500 to have the valve installed. For buyers I recommend not having it installed but to get the money from the seller for the valve installation. Then put it in the bank or be prepared to give that amount to the next buyer if they insist on having the valve installed or getting the money to do it themselves.

Globe valves are often chosen when precise pressure control is needed. They are also employed for on-off operations. These valves feature a vertically positioned valve plug that can be raised or lowered by the actuator. Due to their S-shaped passageway, they tend to cause greater pressure drops compared to other valve types. Globe valves are well-suited for flow regulation and throttling functions.

The valve is a mechanical part. And anything mechanical can and will fail. When the valve fails, the water pressure in your home will be next to nothing or extremely high. So you paid to have this unnecessary part installed and now you have to pay to have it fixed and deal with poor water pressure until you do.

In the last five to 10 years, we started getting calls from customers asking about pressure reducing valves. What wasn’t an issue before suddenly not only became an issue but is also getting worse with each passing year.

The diversity of operational conditions in the oil and gas industry has led to the development of numerous valve types. Each type offers distinct advantages and drawbacks, making it essential to grasp their applications to ensure efficient operation within the industry.

Choosing the right gas valve can be challenging due to the variety of types and functionalities available. Determining the primary function of the valve and assessing factors like pressure levels, the need for additional safety measures, and automation possibilities can guide the selection process. Environmental considerations also play a role in selecting suitable valve materials. By considering these factors, the optimal valve for a given process can be identified.

Given the array of environments they are employed in, there are several types of gas valves commonly used in the oil and gas sector. Below is an overview of seven such types:

Residential water pressure typically falls within the 45 to 80 psi (pounds per square inch) range. Anything higher than 80 psi is considered high pressure and that is what we will be discussing.

Radiant heat is the most comfortable and efficient form of home heating. Radiant floor heating systems conduct heat through the floor, which then broadcasts ...

Water pressure changes. It’s the nature of the system. So unless the water pressure is constantly at a higher psi, we don’t recommend installing the valve.

A pressure reducing valve is exactly what it sounds like, a valve that reduces the water pressure in your home. And water pressure, as you probably already know, is the force with which water flows through your pipes and out of different fixtures like faucets, toilets, and water heaters. High pressure is strong and low is weak.

The oil and gas industry relies heavily on the efficient flow of materials through pipelines, a task that necessitates the use of reliable equipment. Among these crucial components, gas valves play a vital role. These devices regulate the flow of oil and gas, allowing for precise control over the movement of liquids and gases within pipelines. Gas valves manage fluid flow by starting and stopping, adjusting quantities, controlling direction, and maintaining or relieving pressure. To cater to diverse operational environments, a variety of gas valve types have been developed over the years. Understanding these types is crucial for ensuring the safe and smooth transportation of materials in the oil and gas sector.

And two, all the manufacturers test their fixtures from 150 to 200 psi. Meaning, these devices — faucets, toilets, water heaters, etc. — are made to handle a psi from 150 to 200, and homeowners are being made to worry about 80 psi.

Slam-shut valves enhance equipment safety upstream or downstream. Positioned before regulators, they automatically close upon detecting significant pressure changes, necessitating manual reopening. Also known as relief and safety valves, they are indispensable in preventing accidents and injuries in the oil and gas sector.

Of course, I’m not saying you should never worry about your water pressure being too high period. But here at In-House Plumbing Company, we do believe it’s a very rare situation where it’s necessary. And if you think you might be one of those rare cases, we are happy to talk about it with you.

Rotary ball valves are employed for rapid shut-offs in situations demanding tight seals. They are most effective in fully open or fully closed positions and are not ideal for regulation or throttling. Available in various styles, such as floating ball valves for low-to-medium pressure pipelines and trunnion ball valves for high-pressure conditions, they offer ease of repair, strong sealing, and swift shut-offs.

Among the most prevalent in the industry, gate valves employ a gate mechanism to completely open or close pipelines. These valves are ideal for maintaining controlled flow rates. When fully open, the unobstructed channel enables smooth passage of even slurry fluids like crude oil. However, gate valves are less suitable for applications requiring throttling due to the absence of noticeable pressure drops upon usage.

For sellers, I recommend not agreeing to install the valve and to just give the buyer the money so they can have it in case they decide to sell in the future or install it themselves.

We went out to a house once where the valve had failed and there was very little water pressure in the house. It wasn’t at either one of the two place I mentioned and nobody knew where it was buried along the line.

Water pressure valve

In these cases, typically the home inspector for a buyer comes in and does a pressure check. If it’s higher than 80 psi, the inspector recommends the buyer get the valve.

Not to mention there is no industry standard when it comes to where the valve is installed. Usually it’s installed in one of two places, buried in the ground on the main water line either near the area the water line goes into your home or at the water meter. But again, because there is no standard, the valve can be anywhere buried under the ground on the line.

There’s also a lot of information in the other blog posts that might help you understand better what’s going on with your home’s system.

A gas valve is an apparatus designed to regulate the flow of oil and gas. By opening or closing apertures, the volume of fluids passing through pipes can be managed. Valves enable fluid control by means of starting and stopping flows, regulating quantities, adjusting flow directions, and managing pressure levels.

And home inspectors are going to continue to recommend the valves. Like I said, it’s a liability issue because of the current codes. So my recommendation for buyers and sellers is this.

However, for the plumber, it’s just another revenue stream. He can easily show the homeowner the code and say that if this valve is not installed, there’s a risk of damage to the plumbing fixtures and even flooding.

One more important thing to note, the water pressure in any neighborhood can fluctuate. You can see 100 psi at one point and then 80 at another. One system in the neighborhood can show 150 psi and another show 75.

Usually it’s installed in one of two places, buried in the ground on the main water line either near the area the water line goes into your home or at the water meter. But again, because there is no standard, the valve can be anywhere buried under the ground on the line.

But we didn’t stop there. My master plumber, Bill Hoyle, and I went to a trade show a few years ago to talk to plumbing fixture manufacturers. We wanted to know if this was an issue we weren’t understanding, and if so, should we change our stance on it?

Check valves find utility in gas refineries where preventing backflow is crucial. Operating under pressure, these valves prevent the reverse movement of fluids, thereby averting cross-contamination of products. This eliminates the need for an actuator and requires precise installation to ensure optimal response to fluid pressure.

Comprising a plug-shaped disc with a horizontal passageway, plug valves facilitate fluid movement when in the open position. A 90-degree turn of the actuator blocks flow through the pipeline. Although not recommended for throttling, these valves are suitable for unrefined oil products in applications like biogas production.

Our stance: If a home that is 10, 15, or 20+ years old didn’t need the valve before, why is it suddenly a problem? There haven’t been any part failures or flooding because of the water pressure so it’s extremely unlikely the valve is now a necessity. Of course, there are always exceptions but for the majority of the cases, the valve is unnecessary.

For the home inspector, this is an issue of liability. The city code for new home construction states the psi cannot be higher than 80. So any new home will have one of these valves installed. So the home inspector will always recommend getting the valve installed in any home, new or old, with a psi of 80 or higher.

Butterfly valves boast simple construction, light weight, and compactness. They regulate flow using a disc-type element controlled by a rod. These valves can manage high-pressure pipelines and enable easy material flow. Their tight closure when shut makes them suitable for large-diameter pipes where gate valves are not applicable.
