Brett, the Noskum from memory has about 1% HF with 30 - 33 % HCL. I haven't found this to be strong enough with some past issues and unfortunately the only way is to dose it yourself ( far cheaper as well). Were you using hot water at high pressure or just trialling by hand? One of these days...

W@$3% E*543!2$$ springs to mind, probably chief cut throat. He tried the same on me when we crossed paths on a quote. He took a step back when I told him I had 4 yrs Uni Chemisty behind me and the caustic or soda ash would only increase the pH of the acid rendering it less effective. To think...

The Jetwave I have, threw the unloader after three weeks, the gearbox after 13 months part time use( I know of 5 other guys that have had a problem with the gear box/keyway), and this is with constant babying, so much so that I made it an open gun as I was worried the unloaders were continually...

Don't Jetwaves Suck!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Thanks a bunch guys, I'll get a coulple of new ones tomorrow. Cheers Jason

Hi all, does any one know what purpose the spring loaded part that is central in the picture does. The part is a PA #VS 220. I am assuming it is an unloader, does anyone have any ideas on what it is or does? I noticed some leakage from both my boilers today as soon as I put it...

That was the first thing I told the construction company, I basically asked them how much it was to replace the Granite (Imported from China) our price came in at 12% of the replacement cost. The company that makes the grout basically said if you have to regrout it at $20 a bag and maybe use 2-3...

This is a job I got last week at a local mall. When the masons laid the granite they used a chemical resistant grout, but failed to wash it off until the next day. The latex had set and any type of acid wouldn't affect it with any dramatic results. So I enlisted the company that I do some work...

The swivel will only work when you pull the trigger in the gun with a pressure actuated unloader, but with a flow actuated unloader it should swivel all the time. Maybe you bought the wrong type of swivel- there is ones desingned for the free action of the hose, and there are ones used for...

BTW - the better the soap you will have to reapply the acid - it took me a lot of searching for a solution to realise this is the easiest way. So rather than a two step - I'm doing a six or seven step....................................

Hey Dan, why don't you make your own ............................you will save a heap of dough in the mean time. The comparison from downstreaming to upstreaming was that I used the same amount of soap. I've been doing this for the last six months and I'm pretty happy with the...

Upstreaming "rocks" for vehicle washing. I also use it through my steel eagle for flat surface cleaning. As far as degreasing (Heavy) - upstream, heat and a rotojet works great. I've never been to concerned about the pump, it is the workhorse and it may wear out. I just factor this into the...

"Lateral Epicondylitis" I have a patient in the student clinic that has a chronic case of this. It flares up every now and then so he comes in for a course of treatment over 4 weeks with Ultra sound, Cervical and Elbow adjustments, Ice massage and moving on to stretches as it gets better...

You can just run the bypass hose into the tank put a weight on it to stop cavitation. The neater way is to get a 3/4 inch tank fitting, fit it to the tank just below the fill level of the tank. You can use 1/2 inch garden hose for the bypass as long as it is kept fully open it won't be under a...

Your right it is heavy but you do get used to it. I tried to get a 500 bar Tee valve to cut down on the weight when I first tried to toy with it but I couldn't get the right configuration to work so I had to stick with two valves. I guess the weight is a trade for Carpal Tunnel Syndrome without...

Here's my open gun with a QC at the end to change wands as well all my lances have QCs for changing nozzles.
