I’m a PhD student, whose field is glaciology, and I’m in need of a steam drill to make some holes in Himalayan glaciers.

Ideally, I’d use a Karcher hot water unit, however this is very much out of my price range. Instead, I’m looking to build my own steam drill, from a diesel powered cold water unit.

How can I heat water leaving the pump on a budget?

Practical suggestions welcome! A am

I appreciate this may be a peculiar post but pressure washers are a choice too for glaciologists!!!

So i want to pressure wash the parking area of my building and want to know if there is anything i should know before doing so. The floor tiles have dirt build up and the walls havr a bit of dirt also. How should i go about taking this on?

I had an Easy-Kleen 4000psi 4gpm and I’m wondering for my next one I should consider the BOSS? Just wondering because there is a reseller next to me but I don’t know much about it and if the quality is good in comparison to EK.

I have a home jobbie pressure washer 2700 psi I think with that turbo tip. What will get this out. I dropped acetone on it and forgot about it. Cold water and caustic soda?

Customers always ask how many washes a tank of resin is good for, and there's no single answer. For a fixed amount of resin, the total it can remove is roughly fixed: inlet TDS × gallons of DI water produced = a constant. So the higher your TDS, the less DI water you get, roughly in inverse proportion.

With the same resin, 100 ppm tap water should give you about twice as much DI water as 200 ppm. A larger unit like AKM's 15L makes sense if your TDS is on the high side or you wash a lot, since you refill less often.

What's your local TDS, and how long does a tank last you?

What you guys think?

I'm bidding on my old high school's football field bleachers and tennis courts and need some help on how to price them out. I've cleaned some in the past under my a buddy's company, but have never quoted them myself. The bleachers are about 22,000 sq ft (2 bleachers at ~11k) and the 6 tennis courts are about 35k sq ft. The bleachers are 20 rows Underneath the bleachers is entirely riverjack and rock. There's an asphalt path and old weedy grass somewhat close by, but that's about it. Mostly grime and dirt with minimal leaves. The tennis courts are 6 continuous courts side-by-side surrounded by dirt and weedy grass. Only organic staining and some leaves, but not many. The courts seem to be an asphalt base with a rubberized tennis texture rolled or painted on. This is in Virginia. No obstacles nearby, so don't really have to worry about the surroundings. I would greatly appreciate advice on pricing for each, as well as possibly bundling them together. Thanks!

Trying to figure out how this external unloader valve should be set on our predator pressure washer.

We have been starting with the internal pump on 3k psi and the external bypass valve on low and slowly turning it higher and higher as we need pressure. Ive seen conflicting information and AI is no help hahaha.

My pressure washer is now leaking oil at the pump.....

How should these valves be set at start up and how should I turn them when turning off the machine?

Do I start both low and slowly increase pressure on them then slowly decrease pressure on both before turning off?

Looking for a quality aftermarket replacement for Honda 16910-ZDW-003 inline fuel filter.

Do you all use the $50 honda filter? I feel they mark it up 5x.

Does anyone know of or have any recommendations for a cheaper, but still decent quality surface cleaner? I want a secondary surface cleaner that I can keep oversized tips on for lower pressure. I know I can just swap tips on my current surface cleaner, but I'd rather not keep swapping them back and forth. Thanks.

Hey y'all.
Just wondering how professional washers route their hoses to the backyards of the middle attached homes of a row.
Do you go up & over the roof (if so, how?) or do you go through the house (if so, what precautions are used?)

This client has a wooded area in her back patio with large acorns and organic debris that falls onto her new concrete patio (poured ~April '26). Gave it my best bleach based house wash mix and gave it a go with my surface cleaner but it barely budged. I only used the wide tip for fear of damaging the floor. From previous construction experience I know that concrete takes a few years to fully set. Is it possible this gunk is just part of the concrete now or is there a chem that's recommended to take care of it? Before and after wash shots attached.

I have a DeWalt 3300psi pressure washer with a Honda GCV200 engine I use for small jobs. It did sit a few months since the last time I needed it. It cranked fairly easily, but both at idle and in use it “surges” with a consistent rhythm.

I pulled the carburetor, made sure the pilot and main jets were clear and I thoroughly cleaned it, though it did look fairly clean already. After reinstalling the carb I’m still getting the surging.

The engine appears to sit on four grommets on top of the housing which allows the engine to rotate a few degrees when the pump is engaged. During the surging the engine rotates slightly in rhythm with the engine. This occurs both at idle and while spraying. If I put my foot on the engine to prevent any movement the engine runs smoothly, idle or spraying.

And yes I did put fresh fuel in it after I cleaned the carb.

What’s going on?

I have a roof wash job coming up and can’t seem to find any reliable information online onto which type of boots are recommended to walk on one of these. This is a huge house so hitting it from the ground would be difficult and I don’t have a tall enough ladder currently to prop up in the backyard.

Went and put a bid in on doing a soft wash on a 130 unit complex.

I made a follow-up just to check in with them, see what it looked like and just make sure I was still on the list or on the radar. They told me that the numbers that they had gotten back so far and I was half of the next lowest. And on this job my margins all look good even if I have to have issues and have to go rent a unit. I'm just concerned that me being that cheap they might just pass it off.

I want to build a long-term relationship with the community and get recurring business instead of one-time thing.

Hello good people, as said in the title, I was called for a roof wash, never washed a roof before and I want to be prepared, it’s around 2400 sqft, pretty dirty, any tips and tricks are welcomed, from pricing, to washing it, I did some research on the matter.
What do y all think it’s a good price, I was thinking 700-800, 5-6% solution should be enough?
Thanks in advance!

How would you guys go about cleaning this patio up? Drainage appears to be nonexistent.

So this is my first month of operations and I got 3 commercial pressure washing jobs:
1. Welding Shop- $1,100
2. School District -$2,800
3. Mechanic Shop-$200

Im well connected in my city and got all these jobs through people I know and having connections. I’ve done residential houses but most have been for free other than 2 and they were both under $200. Commercial jobs seem to pay a lot better.

Should I focus my marketing on commercial businesses because they pay a lot better from my experience.

Hi All, hope this is the correct spot to ask, if not I am happy to take my question elsewhere!

I hired a company to powerwash and seal my concrete driveway. They came out yesterday and did both. My question, I was under the impression after powerwashing, it needed a day or so for the concrete to dry before applying sealant. Is that the case? Do I need to bring this up? Thanks in advance for the help.

I used Zep purple degreaser and scrubbed with push broom for 15-20 minutes and the marks are untouched. I have a 4400psi/4.2gpm washer with surface cleaner, I just didn’t want to take it all out and set it up if the cleaner isn’t even touching it. Recommendations on what to use next? Should pressure alone take some off?

Im a landscaper and was given this pressure washer by a colleague. Any tips for maintenance etc. before I put it to work?

Does anybody know if there any bigger bottles that fit this?

My pressure washer has been doing this for awhile now, but it usually rights itself and I can get the job done. This time, the problem persisted and I had to shut it down. Any ideas as to what is causing it?
