Replacing a damaged riser tube
In the event of a riser getting damaged and leaking, one of the advantages of Heliocol collectors is
the ease with which the leaking riser can be removed, the leak repaired, and a replacement riser
attached to maintain the uniform appearance of the panel.
A damaged riser is replaced using a Heliocol riser repair kit (consisting of two rubber sleeves and
two plastic plugs), and the broken riser itself.
Note:
Water does not run through the replacement riser. The purpose of the replacement is only to
maintain the uniform appearance of the panel.

7 mm Chisel
Important:
Do not use a chisel more than 7mm wide, as you might damage the adjacent risers as you
remove the broken riser.

Using a 7 mm chisel, and holding the flat side of
the chisel towards the header, cut through the
damaged riser, flush against the header. A round
hole is created in the manifold header.
Repeat at other end of riser and save the removed
riser for use in the repair.
