HOT TAPS
HOT TAPS - AN EXPLINATION
What is a hot tap?
A hot tap is the creation of a branch connection off of an existing pipe (or vessel) without interrupting the flow.
​
When would a hot tap be used?
A hot tap is a good choice when disturbing service to the surrounding area isn't an option. For example, a new fire hydrant must be installed but homes and businesses in the area can't afford to have their service impacted.
​
What are the risks of hot tapping?​​
Rarely, issues to arise during hot taps and can include leaks and lost coupons, where the section of cut-out pipe is lost within the pipe being tapped.
​
N.S. Pawliuk works hard to prevent issues from occurring through employee training. & experience, correct materials & equipment and adherence to industry best practices.
​
What sizes of outlets can be hot tapped?​
The most common pipe materials in Canada can support outlets the same size as the existing pipe. Manufacturers make specialized tapping sleeves for this purpose. Click here to see examples of "size-on-size" taps we have completed.
Certain limitations apply, especially with concrete cylinder pipe. Contact us for more information.
