BlueChem and Vuilders Warehouse

Bought the BlueChem Turboflo 1.1 kw pool pump a few years ago, and it has performed well. The shaft seal has now broken, and the only people who silly spares for BlueChem pool products are Builders Warehiuse, because of an exclusity deal; Builders however, cannot supply the seal, because it is not a stock item. My issue is: how can Builders sell an expensive product like this, which is subjected to wear and tear during its normal course of operation, and then dies not carry any distress for it? So, prospective poll pump buyers, do not buy such items from Builders Warehouse, because you'll eventually find yourself in the same predicament as me, needing a low cost dose part, but instead you'll be forced into having to buy a new machine for 15 times the price. To Builders Warebouse: how you have degenerated into a 3rd - world company, outrageously expensive, and no stock of engen the most basic products.
