Hi Zack, I myself would want a bottom drian for clean out, most tanks have viton or epdm seals ( gaskets) on the lid and drian depending what chemical chart i look at they both seem ok ,viton seems to be better, they all have thier life span with sh so keep an extra gasket on hand. have fun Vinny

Decent outfit there, I've gotten a power washing tank or two from them myself. Shipping isn't a dream, but unless there's a local retailer, good luck finding them cheaper anywhere else....
The tank description states "Molded in 3/4" NPT outlet standard.", so I don't know why it came with two. I think the best course of action us to head to home depot or lowes, and get a 3/4" cap (probably PVC) and insert a garden hose gasket and screw it on to the tank tightly. If you really want to be sure it's water tight, wrap some teflon tape on the threads before tightening it down.
Good luck!

Thanks again everyone! I never thought of having to flush the tank? I think I will put a plastic plug with gaskets on one, and a ball valve with gasket on the other for cleaning.

Yeah shipping was like 80$, but i can see why they have to!

How do you all get your SH from the drum to the tank? An electric pump? Thanks in advance for advice!

hey guys,
I have my complete setup here at my shop. Wired up the 12v fatboy like bob at PT does on his fatboy bandit.  Cant wait to see it kicking, but before i do . . .

I got a 100 gallon poly transport tank form tank depot -
and it has 2    3/4" drain bulk holes with red plastic plugs in it. What can I do with these? The tech specs dont show these? How can I make it SH proof. Should I get them plastic welded shut? I spent good $$$ including shipping and cant really ship it back?

PS after taking a closer look- the holes are pretty deep threads molded. Perhaps I could put a long threaded plug with teflon tape in it?

Zack

Here are some thoughts on this topic ?


Plug the hole or holes with an appropriate Kynar Plug if, or when you can find one.

Do a Google search on Kynar plugs or bulkheads in your Inside Hole Diameter.

Next time you and anyone else is buying tanks for Roof Cleaning, MAKE SURE and do yourself a favor and ASK the supplier if there are already pre-installed bulkhead fittings already on the tank. You can choose to NOT have these installed.

If you can and especially if you are having a TANK drop shipped or sent by freight to you, make sure to get a tank or TANKS with NO bulkheads or fittings at the bottom whatsoever and therefore you will ELIMINATE that as a POTENTIAL SOURCE for LEAKS.

By always drawing from the top and by being careful what goes into and out of the tank you will prolong pump life and minimize spraying problems and you will never have to replace bulkhead fiitings or SEALS as there will be none to EVER fail.

LEAKING BULKHEADS can CORRODE metal (exposed, unprotected Steel especially)and eat paint FAST and can make your trailer become UNSAFE by leaking onto axles, brakelines, drivelines  (on flatbed trucks) even rusting out drivelines and U-Joints. Be careful with leaks, theyt can be MORE then just an environmental issue, they can be hazardous to your health if not resolved quickly or avoided entirely.

Some use a Poly screen or pool leaf scoop or SS colander when filling your tanks from the lid when or if possible.

It is better to keep debris out of your tank. To rinse your tank you can reverse the flow on a POLY shop vac after your tank is empty and  SUCK the debris in the bottom in the vac with a long suction wand and vaccum hose.

Rinse everything thoroughly so the SH doeasn't have a chance to chemically eat away your shop vac ( buy on on sale and expect it to fail eventually from this type of use. You will not have to rinse your tank very often as long as you find a way to filter everything that you can that you put into it.

I like to put a PVC draw tube from the top and down to about 1"- 2" from the bottom of the tank. If possible put a poly agitator end on the bottom of the tube or screen the chemical mix from the tank to your pump. That will save future problems down the line with clogging and nozzles getting Chit stuck in them.

Another way to clean the tank is to get a electric trash pump from Norhtern tool or Tractor Supply or anywhere they sell a inexpensive poly impellor trash pump and just rinse your tank (after using up almost all the chemical at your last job or diluting what is left so it becomes a VERY WEAK concentration well and then have a separate small tank and suck up any trash and debris with the trash pump and then send that material you sucked up into another tank you earmark as your cleanout tank and then rinse it good afterward.

These are just some ideas and suggestions, there are many more and I encourage all others to submit their ideas here as well.

Just some ideas and some advice from experience. Hope this helps.

Regards,

David W.

Bill, take it down and get it welded. YES, plastic and poly tanks can be welded, I have one!

Hi Dave,
Can you please tell me is PVC and PVC glue gonna hold out on my drain??
(My tank has one already until I replace it with a larger one)
And if you can maybe give me a list of approved materials for this you have tried like, rubbers, plastics, metals, valves, valve seats and gromets?
Are pretty much all plastics gonna last? Just not rubbers?
How does copper react to the love?
This will save me alot of further questions on these materials as I build my system.
Perhaps we should post this info in a new topic specified for sustainable system materials.

PVC will hold up, for a while, nothing is forever, especially in the roof cleaning trades. Kynar and Teflon are about the most impervious to most chemicals especially, the LOVE.

Teflon and Kynar both have an "A" rating for chemical resistency. Any metal will be attacked by SH. Better to use plastics, santoprene, Viton, EDPM, but all these are not going to last very long.

Go to Hypro Pumps or UDOR and check there chemical compatability charts.

Snyder tanks website has a great deal of info on what plastics and Poly and rubbers work and do not work with SH.

"Perhaps we should post this info in a new topic specified for sustainable system materials."

Good Idea, do it so it comes up agin to everyone's attention, Bill.
