Teejet Nozzles are leaking once I stop spraying?

[Ijustwantausername]

What is causing this? When I let off the trigger and pressure stops, the nozzles leak out of the tip what is left in the wand.

I read something about a strainer (which didn't come with the nozzles) would stop the leak. Any advice on what mesh type strainer?

I am using AI11004 nozzles. Thanks.

I've used a no drip check valve. SOLO offers one. I believe it's BP wand universal. Hope this helps.

Thanks. What BP did you use it with?

Make sure your strainer has a silver disk in it. That means it is a check ball strainer and should solve it. Also make sure the strainer is clean.

I've searched and all I can find is the one posted for solo. Does rittenhouse sell it?

Didn't much matter, unless it's a handheld or a metel type wand tip. If the nozzle cap inner diameter is too snug. The support lip holding the valve from moving up the tube can be CAREFULLY, LIGHTLY, grinned to support a better fit. Most all BP's will support.

Oh okay, I guess my concern is whether or not the check valve will fit in the nozzle body. The boom I am using is a SP systems 2 nozzle boom.

I read on teejets website that the strainer and check valve are "not for use" on AI tips.

T-JET had brass check valves for boom application. I don't know full list applications. That's about as much as I got,,, here.

AI tips have a pre orifice assembly that is not compatible with the strainers fitted with the ball and spring check valves. I use diaphragm check valve nozzle bodies and the regular strainers before the nozzles. Much prefer them over the ball and spring checks. Spring checks restrict flow way more than a diaphragm check.

Since it takes 10PSI (if I read right) to get beyond the diaphragm check valve, does that mean if I am spraying at 40PSI, that the water that exits the nozzle is actually being sprayed at 30PSI?

Even if that's not the case, is 30PSI sufficient for those AI11004 tips? I know you like to run 40PSI on yours.
