Do not try to patch pieces in. You'd be doing it forever. Wasting
money and time. When it starts getting leaks, in multiple areas, from
cracks and punctures -- replace the run. Save the drip heads and
barbed fittings. They can be used again.

Get a 100' or 500' (?) rolls and replace *long* runs.

Just sayin'
