I am having a problem with my pw. It will not build pressure when using the tank. But if I plug in the hose it works fine. I am wondering if I have a pump problem? I have checked the inline filter and line and everything is clean. any ideas? BTW my machine is a Landa SGHW 3500-6 w/330 gal tank on a trailer.

Air leaks They will getya:lgwave: Thanks All!!

Yes it used to. pldoolittle I did not think to check for air leaks. I feel kind of dumb now :banghead: . Will give that a check after I get home from work.:bouncy:

What would the cons be for making a stainless coil for my kero fired boiler. Other than cost, I can bend the coil. I would most likely use 316

Thanks guys.:)

Please bare with me as I am new at this. Is it possible to "pump" chemicals into a DS instead of lowering the pressure at the wand. I do however understand I would most likely want some kind of metering pump to determine exactly how much chem I want in the line. My goal is to be able to build a manifold that would allow multiple chems to be used with a switch. Any help would be appreciated

Thanks for your input Russ. I do like your idea for shutting a clutch off via remote. I hope this valve does a better job than regular DS's. Shane

This valve from DEMA seems to be the one!! http://www.demaeng.com/product.php?id=75&catid=28 It will allow chem draw at up to 3000 psi. I ordered one for $75 + shipping of $8. I will let every one know how it works when I get it!!

Don't forget to look at www.craigslist.com

I was really trying to stay away from upstream injection. My machine has upstream (Landa SGHW 3500-6) and the prob is the unloader has a recirc to the tank. Yea I could put it back to just a loop through the pump but I like having the ability of letting it run without overheating the pump. I was looking at the DS and yes I would have to have something like a hydraulic pump to be able to overcome the check valve in the DS at high pressures. I wonder if anyone knows if car washes do it up or downstream? As far as the manifold I was going to use a Stainless block about 6"X2"x2" and then drill and tap to my needs. That also gives me the option to put flow meters and stuff to determine how much chems are being injected and at what rates. Please keep the good stuff coming.

I am new here but I use an 06' F350 SD 6.0 torqueshift CC LB 16' trailer with a Landa SGHW 3500-6. It is a very long truck but it doubles as a rec vehicle for my 32' RV and my wife and 3 kids.
