Having noticed it getting harder to remove broken poly fittings out of PVC pipe lately I laid blame on my 5 year old riser removal tool (assumed it was worn down) and bought a new one. Only type I could find was a was a Pope verision and it hasn't made much difference. Anyone know of a better brand? I tried out Bunnings Garden Rain brand in store (took a sprinkler with a broken nipple inside) and I couldn't get it to budge. Neither could one of the staff.
