Industrial Pitless Units include a variety of components from the Well casing options, to the discharge housing to if its a normal or flowing well. Some questions, so how do you find the answers?
When it comes to the discharge housing specifically, there are a couple of options you can choose from and we will help you determine which one will work best for you and your application.
In this blog, we will go over the well casing options, the discharge options and how to ensure you order the correct thing. Let's take a look.
Connection Options for an Industrial Pitless Discharge Housing
The variety of options available for an Industrial pitless unit enables the installer to connect the pitless unit to the well casing and also to the service pipe. In the below photo, you can see the different parts that make up the industrial pitless unit and see where the discharge housing and the well casing are.
Well Casing Connection Options
Welded
The first connection option is welded which is the connection style that is supplied with the Boshart pitless units. It is a standard MPT x beveled end adapter good for welding the unit directly to a steel well casing.
Flanged
The second connection is a flanged connection. When a flange connection is desired, a MPT x flanged adapter can be ordered. This style of connection is ideal when the installer is using a PVC well casing and would like to connect using a PVC flange. There are some cases where the installer will weld a flange to the steel well casing and they then choose this option to connect the unit to the well casing, instead of the traditional direct welding.
Quick Connect
Another connection option is the quick connection. The quick connection flange is a great solution for installations where it is not practical to weld on site. The quick connect MEGA flange provides a secure and watertight connection using basic tools.
Isolation Flange Package
An isolation flange package is also a connection choice that can be used when joining dissimilar metals, typically a 304 Stainless Steel Industrial pitless to a steel well casing. It is highly recommended to use an isolation flange kit to avoid the risk of galvanic corrosion occurring.
Nipple & PVC FPT x Slip Adapter
When you join a pitless unit to a PVC well casing, you can use a nipple and PVC FPT x slip adapter. This is a less expensive option but you must be sure to work with this flange with care and not over tighten the FPT connection. If overtightened, it could result in stress cracking of the FPT connection on the PVC adapter. The flanged connection is the superior option.
Discharge Connection Options
Flanged
For discharge options, Boshart Industries has four. The first one is a flanged discharge connection. If you want a flanged connection, a nipple and FPT flange can be ordered (similar to the above well casing connection). These are ideal when the installer is using HDPE service piping and would like to connect using a HDPE flange or ring assembly.
Mechanical Joint (MJ) Connection
Mechanical couplings are a great solution for any installation that welding on site is not an option. You use the MJ couplers in conjunction with a plain end nipple which would provide a secure, watertight connection using basic tools. The MJ couplers also allow for some deflection of the connection to compensate for shifting soil conditions.
Plain End Welded
A plain end (beveled) nipple is also available to be purchased for welding a steel service line directly to the unit.
Swage Nipple
If you need the discharge to be reduced to a smaller diameter service line, it is recommended to use a swage nipple. The swaged profile minimizes turbulence and friction loss. You can also use swage nipples when the service line is transferring the water a far distance. A larger diameter service line is required to reduce friction loss on the run of the piping. The swage nipples can also be fitted with a flange to provide additional installation options such as a HDPE flange.
Ordering
When ordering your pitless unit, certain types of connections and other accessories are sold separately and are listed on the order form. The order form is specifically designed to walk you through the selection process in a logical fashion, ensuring all of the information that is required is completed and accurate.
