Three cheers for Gilmour Hose End Sprayer!
I've used a Gilmour hose end sprayer for numerous purposes for years and years! I find it much easier to use than lugging around a pump up sprayer and it lasts much longer. I bought several extra container jars to use with different products I sprayed such as sea weed, fish emulsion, fertilizers, etc.
The box says 'Lifetime Replacement Policy" so when the plastic pick up tube broke I emailed the Gilmour-Customer-Service-Department for a replacement of the tube. Lo and behold -- they sent me a whole new sprayer! Yay! Three cheers for Gilmour.
Incidently, after using I spray WD40 into brass nozel to keep the adjustments working freely.
