OK...looks like it's supplying two distribution manifolds, one on each side of the building? The by-pass is indeed above the J-box and it appears to be nearly closed...so that's not the issue. There's absolutely no need to have any pressure on the system, let alone 18 psi. It's a...

Oh...you DID state it's a 5 bay, didn't you! (reading skills are failing me faster than I care to know!)

slash, How many bays? What's the outside air temp? Re: infrared gun. Thye work best when aimed at non-reflective surfaces. So, a patch of the flat black spray paint or a wrap of non-shiny black tape on the copper piping will provide some reasonable data. Measure the outlet of the...

I.B., Good solution but, not all facilities are equipped with "pressurized" hot water.

slash, So, why is your boiler bouncing off the high limit? There are 4 or 5 possibilities: Low water flow Temperature setting too low Interrupted pump operation Modulating control set too high Excessive by-pass flow Low water flow is possibly due to an eroded circulator impeller. This is why...

slash, Short term, this should not be an issue. I'd be concerned about the frozen trough plumbing, unless that loop is staying warm. Otherwise, it may be in you best interest to close the car wash and purge all the bay supply until the sub-zero conditions pass. These systems are typically...

slash, First...the design temp for most floor heat systems is usually +10 degrees. You should not expect ice free performance at ambient temps below the design temp. That's also why your home's heating system has trouble keeping up with the unusually cold nights. As for the gas valve short...

The “Automatic” high limit stat turns off the gas valve when the set-point is achieved. The “Manual” high limit stat is there as a backup…to prevent overheating in the event of an automatic high limit failure. When the manual stat trips, it could be an indication of too little flow through the...

area123, There are several sources for car wash supplies in OK and surrounding states: Jim Coleman Co. and Kleen-rite in Texas. Dultmeier is located in Omaha. HPWS and Lee Soap in CO. There are several equipment/chemical distributors in OKC. And, there’s likely a regional blender or two...

I was an early adopter of in-bay credit card acceptance. Although I was somewhat disappointed in the initial customer acceptance, I did not expect revenue increases…it was just another way to pay. 14 years later, credit card sales indicate a stronger move to cashless transactions in general...

HCW, Your floor heat boiler is a copper tube-fin boiler. Basically, multiple copper pipes are bundled side-by-side above the burner, creating a large instantaneous heater. When the burner fires there must be significant flow through the tube bundle to heat the liquid without producing steam...

When I remodeled, I removed the partially recessed meter boxes that were near the center of the bays (who ever thought that was a good location?) and, installed the new boxes about three feet from the entrance ends. My brick mason then added a course of “jumbo brick” to each meter wall...

Your system can work, but you’ll have to overcome the poorly executed installation. To function effectively, every heating loop should be no longer than 200’ with 10% maximum differential. Running equal length loops from the equipment room is virtually impossible, therefore the shorter loops...

Yikes! Hard to tell from the pics but the system appears to be twin 150,000 grain softeners with very commonly used Fleck heads. Check for an installation/service/user’s manual for the model number or post a few close-ups of the heads. Fleck parts are readily available, manuals are...

Other than what appears to be undersized piping, is there something wrong with the current setup that prompted your question?

IMHO, the worst thing you can do is undersize the water softener based upon the monthly consumption. Because car washes enjoy peak days during the “washing season”, the softener system should be sized for those peak days and not for the average daily consumption. An undersized system will...

Every rotating nozzle I've seen has a zero degree tip. What if it stops rotating? (which never happens, right? :rolleyes:) I would never put a zero degree nozzle in the hands of the general public...your customers can due some serious damage. In addition to the tip protectors, using flex...

3 model 623 CAT pumps about years old Cat 623s are piston pumps, with many moving parts. Capable of 1200 psi (when operated at 100%) they are typically set to run slower and more reliably at 900 to 1000 psi. They need a bit more attention and service than the more modern plunger pumps, but...

2Biz, I've solved your freeze up problem. I called my cousin Jake and told him to quit stopping by your car wash to turn on tri-foam when it's 15 degrees. :p

2Biz, I find no appreciable difference in foam delivery with the 1/4" hose. A non-winterized brush starts showing foam in less than 6 seconds...a purged brush, maybe 12 seconds. Not a KR customer but I think their blue 1/4" Goodyear is HO0087BL and the 1/4x3/8 crimp-on is HU0406MB. I agree...
