Is there any problem with plumbing a filter inside my buffer tank directly into bulkhead rather than an inline filter on suction hose? If it is okay how long should I make it so I don’t have restriction
Personally I prefer outside due to ease of access, but I guess it could be put on the inside. Just easier for me to service on the outside.

As mentioned I wouldn’t do it cause of ease of access. That’ll be a pain to clean. At least you can fit in your tank to get to it. First time I’ve see someone inside of one…lol

I am going to have a domestic water supply line filter so I figured there wouldn’t be too much debri in the tank to start. is that a mistake? not taking anything for granted. I was going to make it about 12-15" long so there is plenty of water flow. I guess the only draw back is ease of servicing.
And “Innocent bystander”, the center cap is pretty big and taking the picture was a bit awkward but I’ve always been called stretch. Ladies at the supermarket always asking me to grab stuff from back of shelves and up high.

Don’t filter going into the tank, don’t filter inside the tank, filter between pump and exterior of tank with a real filter.

Ok,outside of tank. What order make more sense? Buffer tank, filter, proportioner, pump or buffer, proportioner, filter, pump. I’ll be bait and guess that I can place it after proportioner so it filters the water and bleach and surfactant? Also see a lot of guys running a drop stick with that filter. What do you recommend? Thanks
I recommend throwing away your proportioner. My comment was in regard to a buffer tank feeding a pressure washer. I didn’t catch that you were asking about a 12v suction application, so my apologies for that.
No worries. I have the washer plumbed with filter after tank. Worried about the 12v roof wash. Why should I throw away my proportioner. That’s a joke right?
I thought you meant pressure washer too, my bad. On 12v I have my filter on end of my 1/4” poly tube. I can pull the filter out at any time to clean if need be. I draw chems from the top.
I filter before and after my buffer tank. Helps to keep it clean. I also have a line that runs from my buffer to a ball valve so I can fill up buckets, sprayers, etc. Filtering before helps keep sand and debris from clogging clogging my pump sprayer tips. Just use a large enough filter to where it doesn’t affect flow.
If 99% of your work was commercial vinyl siding you could think about ditching the proportioner.

Maybe I should have labeled my heading different. Still learning the lingo. On my 12v roof Softwash I’m top feeding chems but not 1/4”. I’m using 3/4 to draw. Water is fed from bullhead at bottom 3/4 hose and soap 1/4” hose top feed. I don’t see why I can’t use a 3/4 y strainer after proportioner just before pump to filter all three at once?
In regard to siding washes vs roofs so far what I’ve booked is 50/50. Lots of dirty roofs here with all the oak and shade. I have my pressure washer set up for ds. Any of you guys run a dual injector off the chem bypass pulling from 12.5sh and surfactant? I don’t plan on batch mixing unless I’m using Chen’s other than sh. In this case I guess I need a extra bypass and injector to switch. Thanks in advance for the help
My proportioner lines all pull from the top, including the water. All lines have filters on them that can be cleaned if need be by pulling up the poly line.

I got in one of our tanks once to vacuum out all the silt from pulling from water tanks on dusty oilfield sites. Found a meth pipe in there. Good times.

You just gave up your hiding spot. At least you found your pipe before someone else did. 
Did it make you feel like you were inside a water bong?

Honestly, I was so disgusted that I crushed the pipe with my boot and vacuumed it up. I know what happened. I noticed a couple of my interior light bulbs were missing one day. Knowing our average hand, I made it very clear that if I caught anyone using drugs on my job site they would see me across the cattle guard and then they would be responsible for finding their own way home. So I’m sure one of them was in the trailer on their break getting high as a Chinese kite and heard me coming so they pitched the pipe in the tank. I have no clue how long it was in there. Could’ve been months or maybe even years.
But, yes, it did feel like I was in a water bong lol one that hadn’t been cleaned in years. The water we’d pull out of tanks on location probably should’ve had its own warning labels lol
