I went to a going out of business sale and this powermaster 1404 steam pressure washer was in the corner for sale, but it had a broken tag tied to it, so I took a chance and bought it, lets bring it back to the shop and see what is wrong and if we can fix it,
It's made by Aladdin industries and then private labeled
I think the bottom tank for soap. U need to hook the garden hose to the inlet.
I would love to buy this from you
If you like restoring old equipment, especially the internal combustion kind, you will wonder how you ever got along without a hot pressure washer. I restore old tractors, and you can remove four genratons of oil leaks that look like ashpalt from blocks, transmissions ans axels that would have taken a weekend with chemicals and elbow grease!
I would have hooked up a temporary direct water feed, at the hose dipping into the feed tank. It is not good to run the pump without running water through it. That trashes the pressure seals. You eventually got to doing that. Playing with check valves is bad enough, replacing packing rings is expensive and a lot more work.
its not scale its rust same crap that comes out of house rads a bit dumb making rads and burner coils from mild steel.
Water is the lubricant don’t run without water
An fyi the burner should be shut off but water needs to be run through the gun until you can touch the metal parts of the gun.
thats more of a 1000 psi it should be 4 or 5 times that pressure. good thing thats a commercail pump or you would have already burned it up you can play with the pump or just buy a new one they are $180 last I checked. watching you outside it looks a lot stronger now…maybe pop those last 3 valves. try some Mechanic In A Bottle Pressure Washer Pump Saver it actually rejuves the pump seals. just leave it for a couple of hours and flush it. Don't be a dummy and wash a car without a good flush…don't ask how I know LOL
Hi what size socket to remove the unloader valves from the pump?
I have the pump to that unit. it is proprietary to the unit and does not fit s normal pressure washer.
The burner staying lit for so long just didn't sit right with me. I don't know if I have the guts to mess with one of these puppies
Theres still something going on with that pump. I have the exact same machine at my shop and it would blow a hole through the side of a 5 gallon bucket. Maybe check the other check valves. Just saying good luck and be careful bc ive seen a bunch of them catch fire
I don’t think it has enough water pressure to call it a pressure washer.if it didn’t have that over hot water,it wouldn’t clean anything. Fix the pump mustie.ðŸ‘🇺🇸🤪
Sell it to a restaurant owner
wow – you spent 20 min trying to force water into the unloader. That line the bypass tube. It's to keep the pump cool if you let the trigger off too long on the gun. The unloader releases water into the tank only when there's pressure in the pump.
I have the same style pressure washer!
Descaling
This thing is a steam bomb. Be careful and make sure all the safety are working. It should be a safety valve on this unit make sure it is not stuck. Also it should not run unless their is water flow.
A mechanic turned into a Plummer in one easy operation 🙂
Leather seals probably all deteriorated
Your valve maybe stuck openand or closedespecially if it sat so long
Steam cleaners are just that, seems this one is producing more water albeit hot , but not enough steam or more steam its the steam that cleans up oily and greasy surfaces.
The metal water tank will rust pretty badly and stop up system and jam in pump valves , I made a plastic tank with float and no more yearly problems
I ran 50/50 diesel and kerosene
Works great and descaled it once a year
I found a hotsy pressure washer at an auction, it worked. It bid up to 375 before i tapped out, then i searched up of price and started cussing myself out for letting such a good deal slip past.
What's going on with the relief valve ? Or a pressure gauge ? And that outside door is calling all kinds of ways…! The mess and fumes …? Anyway nice fix on the seizing valves .. and nice job 👠overall…
Think of the pump as a diesel fuel pmp ptessure is increased with each revolution
I bought a used Landa in the 1990's for $500 it was small electric used lasted me until about 2015 the coil finely rusted through. The problem with them is can't really get all the water out try to run it without the water hose connected until it's dry then shut the pump off still has water in it. Then the water sits and rusts out the coil the only way to stop that is to add some kind of Glycol fluid to the coil from a bucket so water in there isn't rusting it away every time you use it. Probably don't need to do this if you use it weekly but most people let them sit for months between uses. Once the coil rusts out cost to replace it is over $1700 not going to invest that much into an old pressure washer that you can replace it for $3500-4500. The burners are simple to maintain usually don't break sometimes have to clean out old fuel easy to do. I mostly used it to clean cars I was working on I just ran a hose tap off my hot water heater which gets to 140F. Not ideal but good enough to melt the grease off of a car.
Hot water are lower pressure than pressure washer because the heat softens the grease and dirt .I have one and it works great I cleaned the coils once with radiator flush disconnect from everything used a bilge pump in a.bucket pump in flows back to bucket for a few hours was clean. Than got another one that was plugged and bought acid pump on eBay used pool acid and let it run till works great now.on my farm I always used Tide soap in a bucket if it cleans Jean it clean greasy equipment. That tire valve is blow out befor storage found easier to stick antifreeze in it and drain before use.reusable that way.
It looks like that pressure valve that you were breathing air out earlier in the video, is probably used to blow out the system in the winter time to prevent the pump from freezing?
My company, HOP Sales & Service was the original seller of this machine (blue & white decal on the side). This is a mid 1980s model. Great unit, though. We still carry all the parts for them. Nice work on the diag / repair.
The burner shouldn't be running when no water is running. There should be a flow meter that shuts off the burner. The flow meters I've repaired/replaced have been magnetic slides. When water pressure is high enough the magnet will slide up and close the contact so the burner can fire. Just house water pressure shouldn't close the burner flow switch, it needs several hundred PSI to move. If the burner is running under house pressure the flow switch is stuck closed and needs to be replaced. Some are repairable. I've taken some apart and cleaned them out, reassembled and gotten them to work. Be careful with the flow meter. You don't want to make steam. This is a water heater, not a steamer. If it were a steamer you'd need a boiler's license to operate it (commercially).
I have owned about a dozen of these over the years. Currently I have 5 units. I'd suggest you keep the temp no more than 160 degrees. It's a lot easier on hoses in the long run. The hoses should always be uncoiled and laying on the ground where it can't melt anything (not across a car hood).
Run cold water through unit till you have good flow before turning on the burner. Before shutting off the pressure, turn off burner and run pressure washer till water runs cold. Only takes a minute or so. I usually run it for a couple minutes so the hoses and fittings cool down. You can burn yourself.
You're right about hot water cleaning much better. And not just grease. Pretty much everything. My shop floor cleans up 4-5 times faster with hot water. But yeah, with grease, hot is a must.
