There is an older gentleman (Roger) that works there that always seems to be there when I go here. He is always very helpful and friendly. He has inspected my Hayward bottom cleaning device several times over the years. Sometimes he says it looks OK and suggests other potential problems or sometimes he tells me a part needs replacement. He seems to be a straight shooter not out just to sell replacement parts. He definitely knows this device well though. He has not charged me when no part is needed, even if he did a total disassembly to look at all the internal parts and do minor cleaning or lubrication. Leslie's is not the cheapest option but they are conveniently located to me and usually have exactly what I need.
