i still have my original solution pipes from new 5 years ago. okay so they have all had new ends numerous times (triggers broom springs to mind) but still work well, only had 2 bursts that worried me, one in a commercial, i just flooded a carpet, that got sorted and the second popped on the way down a set of stairs, some went on the wall paper but wiped off relatively easy. not sure what i'd do if it happened in front of a customer, might be time to purchase some new just in case i think.
