The largest injector that you would need on a LW4000 is a 0.86 which restricts flow to 2.5 gpm, so a 10gpm hot water heater should be able to keep up and can be plumbed straight into the pump. When it comes to hardness in your water, remember that the soap reacts with solids, it does not care...

"what should lp psi be" = I like to start at 150 lbs psi on the soap pump and adjust up if needed. You should not need to go above 200 lbs psi. "how many seconds is a pass roughly" = PDQ figured speed 0 to equal about 42 seconds with no Front Bug or Rear Double passes. Speed 9 should be around...

With soaps the raw ingredients are usually all powders and then RO water is added to turn them into liquids. Buying powders cost less than the comparable liquid because there is less involved in making and shipping it. It usually works as well because it is usually the same soap. Which one is...

Usually when this is happening at a specific time of the day it is caused by sunlight getting on the T-bar receiver eye. I have seen the sunlight reflect off a vehicle and cause the arch to turn too soon; as well as, the sun getting onto the eyes directly. The best option is to replace the...

I use GinSan, but I have seen car washes that operate just fine with both PurClean and ConServe units. Pay attention to the layout. Some units can be difficult to work on.

I forgot that you will need to check the inside of the brass valve body for excessive wear, pitting or anything that may prevent it from making a good seal. If you find a problem then you will need to replace the brass body.

I haven't rebuilt the larger style Lexair, but with the smaller ones, I always cut off the air and cut off the water to the high pressure tank. I drop the level of the water in the high pressure tank below the level of the lexair. Remove the airline and the quick connect. Then I remove the...

My two cents. Both pieces look a lot alike, and wash a lot alike. In the end it really comes down to your distributor. Both machines are well built and engineered.

You know I hadn't ever noticed, but our bridges that originally had a treadle plate all have the black rollers on the entrance side and white on the exit, while our bridges that originally where Virtual Treadles have the white on the entrance and black on the exit. I have always just replaced...

1st issue: Check the foaming material in the pods. 2nd issue: I use their Glow Foam Polish and while I have never seen it glow in the dark, it probably would under a black light. JBS uses liquid colorant instead of a powder so you can turn up the color with little fear of staining a vehicle...

The black rollers go on the entrance side of the trolley and the white on the exit side. The buzzer should come with the Virtual Treadle Kit.

The black rollers go on the passenger side and the white rollers go on the drivers side. They should all be the same size.

Personally, success for me is determined by being able to see a profit when everything is accounted for. That said, if expenses are being well managed then you know what your gross income needs to be to turn a profit. Knowing the average daily car count and average sales price will tell you if...

You would still have to use the PDQ VT Board, but the ultrasonics and VT eyes from Wash World wold probably work.

i discovered the forum and joined in 2004.

I run the first soap pass at speed 5, the second soap pass at speed 7, waxes and spot free at speed 7, polysealant and drying agent at speed 9 with the water saver on and set to 400 psi., first high pressure rinse pass at speed 0 water saver off and set to between 1100 and 1200 psi., any...

Just based on what you have told us so far, i would say bad idea. However, it would be nice to have more information. What is the speed on the road? How hard is it to turn across traffic into the lot? What is around the lot (ie. restaurants, grocery stores,c-store, etc.)? What is the...

In a LW4000 there would be heat tape in each rail (the end caps bolt on for access), each bridge rail (there is a square plate at each end of the rail for access), there should be a small piece of heat tape under each eye of the entrance eyes, exit eyes, and T-bar eyes. If the LW4000 has been...

If you are considering putting in a friction unit, why not put in a mini-tunnel. The cost should be less than 2 Laserwash 360+'s. They can generally do about 36 cars an hour in a 35 foot bay.

I have thought of using the Cryptopay for our ACW5's but I am worried that it would throw off the reports, which we use to verify that there haven't been any successful cheating attempts. Currently, we verify with both the count of the ACW Controller's Audit Report and the count on the POS's...
