7. Using pipe couplings
7.1 Using custom couplings
If you use custom couplings to connect the water lines to the UrSpring, please note the
following:
● The valve block of the control unit is made of plastic. Make sure that the internal thread
of the valve block is not damaged during installation by the thread of the custom
coupling used.
● Only use couplings with a 22 mm (3/4") BSPP, non-tapered (parallel) external thread for
screwing into the block.
● Make sure the coupling is not deeper than the maximum thread depth reach of 15 mm
(0.6”).
● Only use liquid teflon for sealing the pipe and fitting that is to be connected.
● Never use hemp (hemp will swell in contact with water which can lead to damage of the
valve block) or organic grease.
7.2 Using John Guest quick connect couplings
The UrSpring package contains John Guest quick connect couplings. Those couplings can be
used on a 22 mm (3/4") pipe made of plastic, and copper. When using the John Guest quick
couplings in combination with stainless steel pipes, the pipes need to have a groove. (see
separate John Quest datasheet).
To insert a pipe in the quick connect coupling:
1. Insert the pipe in the quick coupling.
2. The coupling touches the internal O-rings seal.
3. Push the inserted pipe fully into the quick coupling.
4. Pull the pipe, in order to ensure a force-closed
connection.
