8.6 Installation of Union-style models (FV-15-U and FV-2-U)
Union style valve bodies are available for 1.5” and 2” FlowVis models and are
designated FV-15-U and FV-2-U, respectively. The Union style valve body offers two
main advantages:
1.
Ease of installation for retrofitting to existing plumbing, and where it is
difficult to ‘spread’ the pipe for the standard FlowVis valve body, and;
2.
Where the user wishes to uninstall the FlowVis during cold winter months
As with all Union style fittings,
it is essential that accurate measurements are
taken
before cutting out the section of pipe. The ends of the cut pipe must be cut
square. Removing too much pipe will prevent the union fitting from tightening up,
and leaks will occur. Cutting out insufficient pipe will result in difficulty inserting the
valve body in-between the unions.
