Ok here is my problem.
I ran my lines 20 ft from bottom of drum, through a pvc pipe[for protection and mounting] that is 10 inc above the height of the 20 gal drums.
Now my manafold is simply valves that connect to T's by a short piece of 3/8ths line. Then i stacked 4 of them. I could'nt find the right elbow for the last T. So i used a short piece of hose and capped it.
Now here is the problem/question.
If i open one valve and open my UPSTREAMER it wont draw untill i un-cap the T.
It wont draw and i get no water from the wand if i leave it capped.
What the heck am i doing wrong?
TTTT is what it looks like. I have it mounted vertical.
I dont get why it needs to be vented to draw.
Even after all the air is out of the line if i cap it off it stops drawing,then i loose water,and the hose that comes out of the burner that has the downstreamer hop's around.
I need to know if it's my set-up or if something is wrong with the variable upstream?
Because it did'nt do this befor i added the langth of supply line im sure im doing something wrong. Then again my unit sat for 53 days. I did check every hose clamp.

Ron,

Looks like you are still online give me a call, I am just now leaving office but phone will forward with me to my cell.

It sounds like it is trying to pull through a vacuum. The vacuum will let the little check ball stay in place, and not let you suck chemicals. It is kind of curious. Have you tried to lay it horizontally, instead of vertically, to see what happens? This is really unusual soundig to me.

i never took a UPSTREAM valve apart. For some reason i dont think it has a ball in it like a DOWNSTREAMER.
I was thinking it was just like a valve on your house that you use to turn the facaut on and off with.
I could be way wrong.
When i first hooked up everything it worked fine. Went to job and got screwed-up.
It is just soap im running through it.
For some reason i think it's plumbed like the drains in your house. They need a vent to drain. The upstreamer should pull, not work like a drain.
If you have a positive displacement pump and leave the upstreamer open and have no liquid to the chem line. Then you are sucking in air before the pump.
I dont know why it wont draw unless vented. It works fine with 4 ft of 3/8ths line but not 20 ft without the vent. I dont get it.

Ron,

Typically a needle valve is used in "upstream" soap setup.

Are you just trying to understand why the pick up needs to be vented? Is there some reason you can not leave it vented?



I am not sure I understand your set up, is the siphon tube inserted through the top of a drum, or are you drawing from an outlet at bottom of drum?



Check out the Chat Room.

First does your chemical tanks have vent holes at the top?

 

[ron]

i am just useing open 20 gal drums for chem tanks.
Just drop in the chem line with a strainer on the end.

 

[Larry L.]

Have you tried caping the line after it started drawing to see what would happen?

 

[ron]

bigboy

yes i did and it starved the pump or put air in the supply line because the flow went to a trickle from the gun.
I can run it with the vent i just want to know WHY.
I found the pic of your set-up. Mine is the same except my valves are mounted higher on the wall. Where yours are mounted to the floor.
I'll do some messing around and get back to you.

 

[Larry L.]

It really doesn't make any sinces,where is this capped line in your system?

I have mine my chemicals lines plumbed 1 inch off bottom on the tanks,the weight force of the chemicals could have something to do with it.

O thought you where a jack of all trades???????????,lol,,j/k

Ron:

If it is OK with Bigboy, would you mind posting that picture? I'm looking to do something similar and would appreciate the guidance.

Thanks!

 

[Larry L.]

I do not mind,its nothing fancy,just a redreck setup

 

[ron]

the pic is under "Hi BIGBOY [ACID]" use the search button. A mod can re-post it here. Not a good pic, you can only see part of the set-up. Just valves hooked into T's connected by short pieces of hose. Then hooked to valves that can let them be piped to a upstreamer,downstreamer,or shur-flo.

 

[Mark]

Here is a link to that post, I thought it would be better to post a link to this post than to move the post.

The picture is shown at bottom of third post in that thread.

Found it! Thanks! Redneck setups often work best, and you can't beat the price!
