I'm rebuilding a Navigator cleaner for a friend and I've been up there three times over the week end. Every time I leave I swear I'll never go back, but it's close by and I relent. It was aggravating that they didn't have the most basic of parts - the little rubber shoes that go on the bottom of the cleaner among other things... but anyway. There was another customer who was looking for a small part - it cost $4.50 he was willing to pay them up front for it and pick it up next weekend until the sales clerk told him it would also be $4.50 to ship it to the store. What? Don't you have deliveries coming anyway? Another guy was getting his water tested. He has a salt system and wanted to know how much CYA to add. The clerk told him anywhere between 40 and 90 would be fine. I ended up having to go to Warehouse Pool Supply - they have several Houston Locations. They had everything I needed which makes the trip way less stressful. We're just friends for now, but if things progress I may take it to the next level and let them test my water.
