HydroForce is dropping pressure

[Mikey P]

Filter is not clogged.
If I take the sprayer out if the picture, the gun alone spray fine, hook it back and pressure drops in half but is still drawing chem.

Check the dema valve, check that the small hole in cap is clear.

the one in the handle?

Do you get bubbles while spraying with chemical? A small hole or crack in tube will cause pressure drop.

the one in the handle?

Yes..
And the one in the jug.

Nope

Switch plumbing to backflush the dema block.

Switch plumbing to backflush the dema block.

That's what I mentioned when I said check dema valve. I think there is a clog or "pebble" floating around in there.

The pressure is supposed to drop significantly when hooked through the actual HF. From about 400 psi through your line to 120 or so out of the jet.

I'm guessing you know that, though.

Try the Multi Sprayer brand... Dema Blocks made in the USA at St . Louis.

JonDon has them labeled as Powerforce II

Even if just order the dema block it makes a difference

Can get those dema blocks at dultmeiers. Of course they won't have that hydroforce brand name stamped on them : )

Did you run turtle wax through that too!

 

[Mikey P]

is that a problem?

 

[steve_64]

It was on your other sprayers. What makes you think the hydroforce would be ok?
