The Chapin Industrial Stainless Steel sprayer is heavy duty and very high quality unit. The tank is heavy weight stainless and the pump is brass. Chapin uses a Tri-Lock to seal the pump handle to the tank. The Tri-Lock is built to last. The rubber hose is clamped to a stainless nipple coming from the tank which makes for a strong and long lasting connection. The Chapin plastic tank sprayers use a much cheaper and weaker system. The plastic tanks have a threaded hole in them. Then a plastic threaded adapter screws into the tank and the rubber hose clamps to the adapter. My old sprayer tipped over and pulled on the adapter which ruined the tank. The stainless sprayer is built for professional use and will last if it tips over. You will need the separate Chapin fan tip if that pattern is needed. Forget the other sprayers, buy the best and it will last for years!!
Awesome product... granted my home lot is only about 12,000 sq ft (.25 acres). But this thing performes like a champ... ran about 8 gallons on the first use, very durable, the nosel adjustments are great that offer good precision . Looks and feels extremely durable. The only plastic type of parts here the wand holder and the hose , other than that everything is metal! It does get a little heavy after a while of use but nothing that can't be solved by strapping on the sling.
