Which pressure washer to clean out black tank?

I just bought a pressure washer kit to clean out my 150' french drain in my back yard.

https://www.amazon.com/gp/product/B0...0?ie=UTF8&th=1

Got me thinking I could shove it down the toilet and clean up my black tank. Scared my gas pressure washer might just blow everything apart. Choices of pressure washer:

1. Gas 3,200 psi and it is a beast
2. Electric 2600 psi
3. Electric 1100 psi

All are equally easy to use but thought I might go with the #2 instead of the beast.

go with the beast . most come with different nozzles for wider spray and less force when needed . then when it comes to cleaning the driveway you will have the power needed . imo

Oops, I wasn't clear. I already own all three of these pressure washers.

A pressure washer is a little bit of an overkill, besides you only be able to shoot straight down. Get one of these:

My pressure washer has a 3 ft long wand with about a 45-degree bend.........that was after I accidentally stepped on it. I don't recommend the modification. Otherwise, it works great for almost all applications.

I have that kit I linked from Amazon that has a few different multi-directional nozzles with it.

I don't see an end that will only shoot sideways and not potentially back towards you. Be prepared for getting sprayed, and hopefully just with clean water.

Instead of going down the toilet, try this approach:
  • Empty the tank.
  • Crawl under the trailer.
  • Inspect the black tank and determine on which side of the tank the sensors are located. They are easy to spot.
  • Pick a wand/nozzle that will spray in that direction when inserted in the black tank outlet.
  • Take off the drain cap.
  • Open the valve.
  • Insert nozzle and spray.

The one nozzle only sprays backwards to draw the hose in further. And it rotates.

I could go in the out hole with the hose and nozzle but that's a recipe for poo face.

Ok, that is not clear from the link, photos, or the description that says rear nozzles lol. Best of luck staying dry and clean. I do see where it shows then pushing it down and then sideways. Maybe that helps.

It's still worthwhile to know where the sensors are, even if you are putting a wand down the toilet, so you know which way to face it.

I ran across a video like this (maybe the same but it seems it was last year sometime). Maybe it would help?

A whole lot of talk, talk and more talk. Just get to the point!

By the way, it's not advisable to perform a Fred & Ginger routine on your roof.

I am not putting a wand down the toilet. I am putting a hose with a nozzle on the end down the toilet. It's a snake like used in plumbing.

Go with the 1100. Dump and flush tank if you have a flush. Get you one of the following and put the pressure washer in the small cam up to the tank, wrap a cotton rag around the hose and push it in and out. When done pull the hose just far enough that you can close your dump valve, have a tub of some sort under the small cap during this process. Once you remove the pressure washer hose and drain what's in the pipe between the dump valve and the cap, hook up and dump.

CAUTION

I wouldn't use a pressure washer of any type in my black tank.
If you have a black tank flush, that's plenty. Simply run the black tank flush for 30 to 60 seconds and give it a rest. After 10 to 15 minutes, time enough for solids on the tank wall to emulsify, run it again. Use a clear dump adapter to monitor the output. If you notice that you dislodged a significant amount of solids on the second pass, wait a few more minutes and hit it again.

If you don't have a black tank flush, use something like this tank rinser.

Household water pressure is about 60 PSI +/-. The rinsers might create the illusion of a jet of water at slightly higher pressure, but physics says not. The increased velocity of a small nozzle at 60 PSI is more than enough cleaning power. I may be alone in this opinion, but there's not a chance I would put the wand of a pressure washer down my black tank at 1100 PSI +. I use my pressure washer to strip paint and remove stain on decks. While the plastic tank might be fine, I can't imagine the sensors and seals in the tank tolerating that kind of pressure. But that's just my opinion.

Yeah, I'm thinking that pressure washer nozzle thrashing about in the black tank might take out a sensor. I have a tornado installed and don't have any issues with sensors so may just leave well enough alone.
