NoTap® Pipe Blocking
NoTap® pipe blocking is a complete system for easily and economically repairing pipes and installing or replacing equipment in your pipe system, without having to drain the system first. Sections of pipe to be worked on can quickly be temporarily isolated by means of internally blocking the pipes with inflated balloons.
The NoTap method can be used for hot water, fresh (tap) water, compressed air and refrigerants (glycol and salt based solutions). It is suitable for all pipes of metal, for example: black steel, painted steel, galvanized steel, stainless steal as well as copper. Valid for both thin-walled and annealed tempered pipe.
Blockings can be carried out on pipes up to DN50 (2") and connections up to DN300 (12").

- Work can be carried out during normal business hours, eliminating the need for costly weekend or after hour work
- Less corrosion in the water system for increased life expectancy of the system
- Reduced risk for water damages due to faucets left open
- Environmentally friendly
Blocking is done by inserting a balloon into a pipe by means of a hole drilled into the pipe through a mounted clamp and then inflating the balloon. The section of the pipe to be worked on can thus be isolated without having the expense and trouble of draining and then re-filling the system. When the work is done, the balloon is deflated and removed, and a sealing cap is mounted to the clamp.
With NoTap you can carry out repairs and branch connections without first draining the system. You will save a lot of time and money and the method is simple!
Installing and replacing valves and pumps
Are you replacing a valve, pump or mixing valve in a system? Try our method of pipe blocking on each side of the valve or pump first. Then do your replacement with ease.
Repairing leaks
Do you have a pipe that is leaking? Try our method of blocking on each side of the leak. Then repair the leak quickly and easily.
Installing heat pumps, boilers and heat exchangers
Use NoTap when you need to rebuild the heating system. The installation will go quicker by using our method of blocking and you will avoid problems with corrosion as no fresh, oxygen-rich water is added to the system.
Heating equipment
With NoTap you will totally avoid problems associated with heating equipment such as welding, soldering, etc.
