Pulling from the top.

†††† As a confessed former bottom dweller, I now pull from the top. Who else pulls from the top of their tank. Tucker told me to do this and once I started, I was amazed. the flow is so much better and more consistent.

†maybe has to do with air, kinda like siphon,the liquid being forced up the shorter leg and into the longer one by the pressure of the atmosphere.

Coming from the bottom, the air is trapped. that is my guess...

from the dictonary

a tube or conduit bent into legs of unequal length, for use in drawing a liquid from one container into another on a lower level by placing the shorter leg into the container above and the longer leg into the one below, the liquid being forced up the shorter leg and into the longer one by the pressure of the atmosphere.

if your lid is tight on the tank when draning from bottom†; isnt there a air lock? or air block?

Whooaah! DOOOAAAHH?! I am feeling a little like Homer Simpson about now.

Im lost, I'm found, ooh I got it...hmmm...nope, lost it again??

Seriously, LOL

Good Call Kid, Raystown....sounds reasonable.

Suction or vaccuum LOCK can from my understanding, have a draw down effect, slowing flow down, especially, when you have a tankful of LOVE and a TIGHT Gasketed LID and when all that is combined when drwing from a leg bulkhead, for example.

Can we all be on the right track and say that VACCUUM slows flow when combined the barometric atmospheric pressures.

What is the Correct answer?

What do you say Professor Chris?

Atmosphere, Vaccuum, ? What might cause this effect to occur?

WE pull from the top to eliminate LEAKS
I would think flooded suction would be superior, as you have in† a Bulkhead situation.
But† air locks CAN slow suction down in a non vented lid situation.
In OUR world, we see no real difference in flow pulling from the top, but have never actually COMPARED.'
Our "motive" was to eliminate the trouble prone bulkhead, and it;s LEAKS.
Having rusted driveshafts break at 70 MPH with 600 gallons roof cleaning mix gets OLD, fast!
Plus, the nasty **** at the bottom of the tanks dont get force fed into your roof cleaning†pumps like it does with a bulkhead.

I used to use an elbow plumbed into the outlet of the tank, with a ball valve. Once the ball valve was opened, the flow would significantly diminish, due to the air pockets. Also, it would leak from time to time.

Once we started pulling from the top, the flow increased, no leaks, and no granules sneaking into the line, right Tucker!!!!!

The only line on my system that I pull from the bottom with is from my 125gal tank using my surflow system. I pull from the top when using my 50gal and always pull from the top when using my Roof Cleaning pump. I used to have 4 different tanks and pulled from the bottom. I have tried to get away from this because of leak problems. Nothing is worse than pulling up to do a Roof Cleaning Job and you find out your fittings are leaking all over.

When pulling from the top do you have to cut a hole for a bulkhead on top or do you go through the opening that's already there?

Some guys cut a hole and run a piece of pvc pipe and run the feed hose into that. I just take the cover off and†drop mine through the top. I do it that way because I use 3 different tanks for whatever type of Roof Cleaning I am doing. Just makes it easier for me.

Me too Larry. I simply pull out my hose and stick it straight in the hole, and let the suction take care of the rest.

It is a good idea to place a rubber grommet in the hole, and run hose through it ?
Kinda keeps spills down when roof cleaning rig is†moving down the road.

I never ATTACH my hose. i let it dangle until I'm ready to put it in, and then just take the top off the tank.

How can you pull from the top?
Wouldn't you have to keep dropping your suction hose every few minutes???
I just drop my PVC suction hose in my tanks?
I use a screen, but it would be nice to stay away from the bottom dwelling crud!

Put a 3/4" Bulkhead valve in the top?

It has inside and outside threads.

Thread a male threaded to female PVC slip fitting into the inside of the bulkhead fitting after you cut the hole in the top of the tank, and make a 3/4" or even 1" suction tube (make sure to properly measure tube and include fittings and inside bulkhead measurements† so tube only extends down to within an inch or 2" max from tank bottom.

Use from 3/4" or 1" PVC tubing and glue using primer and appropriate glue.

Always go oversized and reduce down, rather than restrict flow and have diaphragm failures RESULTING from pump starvation.

Put an elbow out the top with a 1" CHEMICAL 20 MESH SS or heavy duty poly filter inside and then draw from the outlet flow side of the Spin on filter to catch bottom dwelling crude.

Make sure you use oversized tubing, fittings and ends, elbows, etc. and reduce down to final size for your hose fittings, which are 1/2",5/8" or 3/4"

The end

After a phone converstaion with Roof Clean USA Georgia, I now understand what "pulling from the top" means. It's just NOT pulling from a connection through the bottom!
You put your suction hose in the "top"
I gave up on "pulling from the bottom" years ago!
Lost too much chlorine with leaking seals!
I pull from the top! †smile.gif

I use a bungee strap to secure the hose in place and keep it from sucking the bottom. With the strap, I can adjust the hose as the amount of chem goes down.
