Thanks for that info. I hadn't seen this one before, although I've used other hose-end sprayers.
Do you use the same source for purchasing just the jars?

Don't ya just love it when a company stands by their product? It's become so rare that when it does happen it inspires a celebration!
I've felt that way recently too, although unrelated to gardening products. My kitten destroyed the wires on my new Altec Lansing speakers I got for my computer. I called them expecting to pay for replacements and they sent them free of charge! Maybe it was my genuine appreciation for their product that created the goodwill (very good quality sound for a low end product) or perhaps that's just standard practice for them. Same with Calphalon pots and pans. They'll replace something (and even send an improved and more expensive replacement) with no questions asked. Such a nice feeling and creates loyalty.

Yes, one doesn't mind paying for good quality! Some of the stuff you get nowadays are just poor facsimiles it seems. They look like the real thing, but don't do the job. And good guarantees are just the icing on the cake.

I purchased the Gilmour hose end sprayer at Lockhill Feed Store and they had the extra containers available there also. Regular bottle caps fit to cover the contents. I haven't checked lately to see if they still carry them, but they are very good about ordering anything in their realm of activity.

Had a similar experience. Broken nozzle was 'fixed' by
sending me a whole new unit!

Don't buy extra bottles. I've discovered that a 2 liter
soda bottle will fit the sprayer. Just get a longer
pickup tube. Twelve inches is just right. Cost - $.17.
Yes, that's seventeen cents.

And you don't have to refill the 16 oz Gilmour bottle so often.
Two liters (64 oz)is a lot of whatever you'r spraying.

I have a Gilmour pump sprayer, and had the same results you did when I had a problem. They are a great company, stand by their product, which is hard to come by!
