The small water tube that runs up the slide to squirt water onto the slide needs to be replaced. My slide looks like a standard slide with a curve. I can't find any labels on the slide to indicate the brand, type, size etc. I've seen replacement tubing parts on-line, but am wondering how I know what to order. Are these replacement tubes pretty standard across slide brands? I think I also need to replace the nozzles because water only trickles out. Any help would be much appreciated! Thanks!
