IB, I'm sure you are well aware that the original Mark VII Giant Unloader had a "Hidden" check valve to keep weep from back-flowing. I think you were the one who told me about it. Drove me nuts in the beginning. The check in the unloader is brass and uses an oring to seal. I've got some...

Have you tried this one? https://www.kleen-ritecorp.com/p-3247-kleen-rite-check-valve-38-f-ss.aspx Its not cheap but is rebuildable. I purchased 8 of these a few years ago for when my giant unloaders fail and will switch to a regulator. Seen several manufacturers that used them and also was...

Was going to respond the same thing....All I can find any more is Clean And Protect. I bet its the same as the old System Saver. They also have one that's labeled Rust Remover but have never used it... BTW, had my Fleck 9000 Head rebuilt last summer. Even though it was set to regin correctly at...

Nope, just went back to Morton's and have been a Happy Camper ever since. I get the Mortons at Sams Club for about $5 a bag...

A few years ago, I switched from Morton's to Diamond Crystal Solar Salt. It was supposed to be better for the Softener and a little cheaper. The cost wasn't the issue, it was just supposed to be better. Within a few days after cleaning the entire system and putting in the Diamond Crystal, the...

About the sign...Had a guy stop in last fall and tell me the sign is rare and has value! Like a lot more than I would have thought. He knew all about signs like this. Luckily I know him and told him I know where he lives IF it ever turns up stolen! LOL...It has a manufacture date stamped on the...

For me, its the biggest Thorn In MY Side at the wash. To be there when someone pulls up, empties their garbage, and leaves without spending a dime. I try to keep my head down and not make eye contact thinking maybe they come back to at least buy a pop, an air freshener, or something....Let alone...

Where did you get your information for adding the bleeder hole? I would think it would be just the opposite. Although I have air shut-off Solenoids between the regulators and Flojets….I would never know if air pressure was leaking down! Unless I was there and heard the pump continue to run...

I agree with Mep...I have flojets on PS, FB, and washer fluid for winterizing LP hoses and can't remember the last time I've replaced one. I do have solenoids on the air supplies for "Cheap Insurance"...I lost a few 5 gallon buckets of chemicals with stuck open solenoids and broken...

Same here! Trying to Envision this Work Of Art! Maybe the rest of us are doing it all wrong! LOL... What I learned a long time ago, to get consistency you need to measure volume of all chemicals before they leave the ER. If you make the volume the same for each bay, it takes the different...

So what they are saying, there isn't a book that covers every way a car wash can work. Every manufacture or barn yard mechanic does the same thing differently. I think this site will be your best source for information.

Something to store under your belt....2 pumps in parallel output double the volume and pressure is the same as using one pump. 2 pumps in series output the same volume as one pump but output is double the psi....Something I learned from the hours and hours of research I did when learning all...

Yea, I put this head (With Snap Rings) on a pump and it fit just fine with stock seal cases. Since they are .070" and .100" too deep from machining the head, there was plenty of clearance at the seal retainer since the snap ring is only .050" thick....I still like the idea of making spacers to...

Good Point MJ...There were other pumps available that would deliver the correct pressure when I put in the floor heat. But after doing all the math and research, I decided on (2) 0013 Taco's in series to give me the 40 psi needed. With the main circulator being a 0013 Taco too, I would only need...

Observation I pulled another Vilco Head off the shelf to make some observations on how the process is done and tolerances held. What I found relates to Meps post above. Looking at the photos below, after torquing down the seal cases with #29 oring, SS sleeves and HP seals inserted, the outside...

By the time you add it all up including t-stats to turn on the circulators, you're not far from the cost of an HTP. Although, a little over 4 years ago I got the HTP shipped for $3800! They've gone up a lot in such a short period of time. Something I've wondered if going the demand...

To avoid confusion with the last post. Here is the HTP heater I purchased instead of going the Demand route for the bays.

So you did your homework! I would have to agree that a separate tank/circulator/demand heater might be a better option, price wise compared to what I purchased...At least you'd have full flow through if you ran out of hot water...In another thread you mentioned you got another SS storage tank...

I installed a 199K Takagi in place of a 350K BTU Jarco Webn floor heat boiler. The savings was huge and it worked great!! The savings was big enough, that I just turn it on in the winter and let it come on at 32° without micro managing. So yea, any time you can go from a low efficient boiler to...

Update, Vilco has been very responsive and replied to my emails. Their pricing is on their website. They will actually only do the HP seal area if you want or do the HP seal area plus sleeve the valve seal area... Dynajet on the other hand did not respond to any of my emails or respond when I...
