Mike, Does the ceramic ball keep you from having to flush it out everytime or is there some other reason like corrosion resistance? What is the reason for the gun?

The YRL-50 gun has the largest ball, 13/32" is the largest for a 3/8" size gun. It also has the best feel, with the hydraulic action.

The large openings and a larger 0050 nozzle allows for better flow, hence less back pressure, and more chemical draw.

Try it, let me know how it works.

Yes ceramic is corrosion resistant.

The YRL-50 gun comes with a stainless steel ball unfortunately. Bleach will eat it up within a year and it will start to leak like a sithe.

If you decide to try the gun order a 13/32" ceramic ball and a spare spring for backup, see the links above.

Always aggravating not having backups in the field when murphy's law kicks in.

I have gone through so many guns, I finally found one that I can stick with. All you need is spare springs and a ceramic ball.

The ceramic ball outlasts the springs, buy more springs.

Or if the gun still doesn't give you enough draw.

Use pressuretek's heavy duty ball valve with adapters to fit a stainless coupler and #50 nozzles

It's less comfortable, and not as easy to work with, but it will max out your chemical draw.

Use this one. All the others I've tried are too stiff. This one is the smoothest.

Ceramic is the chit Spencer !
Toilets are made out of it.
Think about it ?

One more thing Spencer, you probably know and use them already but just checking.

The 5-8gpm 2.3 orifice injector works best for 8gpm

and 3-5gpm 2.1 orifice injector works best for 5gpm

Whats up Spencer? Just to add to all of this. I have been using the same guns that came with the machines I've bought since I bought them. 2 from older machines and 2 from newer.Im sure they are not the most expensive guns. I also use the same ds injector that the machines came with. I believe they are general too. I add a water to my sh but also add alot of Dawn. the Dawn seems to make the sh stick to the surface giving it more time to do it's dance and eat up mold and mildew. I never seem to have a problem doing it with this equipt. However I do notice a slight difference when I use the #30 or #40 verses the regular balck soap tip. The black soap tip seems to pull chems a bit better and soap up more. This could be a part of your problem. Try dumping a bunch of Dawn in your mix. It gives a nice silky feel to the rinse process and pulls down webs and dirt like there is no tomorrow. Hope this helps a little. Love you all, Larry
