Garden Sprayer Plasitc.

[Diggin It]

Over the years, I've had more than one pump/pressure type garden sprayer spring a leak for no apparent reason. None of them have been dropped or banged for example. A year or so ago, I was shopping for sprayers again and found a two pack of two gallon ones at that infamous tractor and pet food store for 25 bucks or so.

A few days ago, I loaded one up with grass killer to do a fence line. I now have a trail across my yard where it leaked a fine stream of mix. That trail stops after about 40' so it must have stopped leaking. I pressurized it again and didn't see anything.

This morning I loaded it with weed killer and once charged, I noticed not one, but two very fine streams coming from the radius edge between the side and bottom. They also stopped after a few minutes. I don't get why a less than year old sprayer is leaking or why it stops by itself.

They stopped leaking probably because the pressure was down enough for the seam to close. Try pumping it back up and see if the leak returns. As to the leak itself, if you have a soldering gun you can try remelting the plastic seam to close it up.
