I was disappointed that I could not easily source a replacement o-ring for my cheap plastic insecticide sprayer. No pressure, no spray..
On the WWW there were replacement gasket sets costing up to $20 for a sprayer that cost less than $7 new. O-rings for as low as $1.50 ea if you buy 10 at a time and then add shipping.
I finally broke down and bought another new sprayer (2 year warranty). After assembling it I noticed a new (to me) feature. The new one, looks pretty much identical to the old one with one difference. The new one has a pressure release valve. The old unit required unscrewing the pump body to relieve pressure after each use, or for refilling. Unscrewing while under pressure could cause the o-ring to bind up, and perhaps fail sooner.
Or not, but that is my optimistic hope.
