I have my Python for years and years. I hook it to the kitchen sink using a quick-connect fitting that I bought in the garden section of Wally World. I have plenty of water pressure and I can do a 50% change on a 75 gallon FW tank in about 15 minutes. I changed out the gravel cleaning end for a longer tube with a strainer in it and after years of use, I replaced the plastic shut-off valve with a brass one from a garden supply. Nonetheless, I have never had the hose or the valve clog with sand or gravel. Mine works like a charm and I use it to empty and refill 8 FW tanks on cleaning day. No buckets. Unfortunately I can only empty the SW tanks and must refill with buckets and a pitcher.
