Why use purple primer on sche 40

[Waterwelldude]

My point exactly.

Some swear by it, and some don't.

Good luck

Oh yea, The air line is just over 15 years old, and still in use.


I do like the smiley

No I am not, lic. plumber. Never claimed to be.
I take no offence to anything ask about me.
I never make a statement I can't prove, or is untrue.

Waterwelldude now that brings up a couple more questions.

1. Do you provide plumbing to others in Texas?
2. Since you are not a plumber how do you know your state does not require you to use primer to make a solvent weld joint?

Goodnight Cookie take care.

Waterwelldude,
May I direct your attention back to this post.
I was adding some additional information links you may want to share with your friend who is using PVC for compressed air...
Especially if it is a place of business.

I have to know when its required and when its not.
Within the city limits it is required. Outside in the county, it is not.

I have to know all the codes/rules/laws, pertaining to the project I am working on or with, be it well or septic system.


Because I hold two separate lic.
One for wells, and one for septics.
I don't need a plumbers lic. to do any plumbing directly associated with my job, be it a well or a septic.

Now anything before that, that is where a lic. plumber is required.

Redwood;
I know that its not a good idea to use pvc in this way.
It has been done by thousands of people, and will continue to be used.
Your not supposed to speed, but it happens.

After a bit of on-line research I found that Texas requires the use of primer to be used on PVC pipe prior to the use of the solvent. I find it hard to believe that counties and cities are allowed to make the code less strict.

Here in Illinois the Illinois Plumbing Code is the bare minimum the plumbing can be done, cities , townships and counties can not make the code any less strict, but they can make it stricter. For example the Illinois code says Type M copper is allowed for potable water supply within a building, all odd Du Page county changed the code to that copper pipe in a building for potable water supply must be at least type L.

As far as I'm concerned Texas needs to hold onto their plumbing ideas and their politicians....

They don't work well for the rest of us...

Read my auto signature...

 

[Cookie]

It looks like to me directions might come on that can?
My kids taught me to read all directions.

 

[Redwood]

Cookie you are right.
It is a case of reading is fundamental...

 

[Cookie]

I am woman, I am always right.

 

[Gary Swart]

Primer is required by code. Sure, you can stick pipes together without primer and it may hold forever. But, it may not. To argue against using primer is pointless and foolish, because you are arguing against code and good practice. Further more, to brag about using PVC for compressed air further diminishes your credibility. PVC can and does rupture under pressure and can and has seriously injured people. The "fact" that you have used it for a long period of time just indicates that you are on borrowed time. Both of your arguments are indefensible.

Cleaner vs. Primer

Are you sure you guys are talking about same...

Waterwelldude is saying CLEANER and there is an Oatey Cleaner


While you others are saying PRIMER.


Would you ever use both???

 

[SewerRatz]

Codes say purple primer must be used. If he was using the cleaner, then he still was wrong.

 

[Gary Slusser]

I used clear Cleaner, and in a pinch rarely only Cement, no primer because I didn't have any inspections and my customers hated purple primer even though my 'plumbing' was very neat.

It's been awhile since I read manufacturers' of PVC instructions but what I recall says, any type of cleaner or primer made for PVC or, All Purpose cleaner and/or primer or cement can be used, including mechanical means such as sandpaper, steel wool etc. to get rid of the 'shine' dirt grease etc.. Which a thinking kinda guy might say... Hey, no cleaner or primer is needed!

So the CODE may call for Purple Primer but it has nothing to do with the strength of the joint, it is a visual used for inspection purposes. Along with the fact that the CODE isn't used everywhere; and geographically, there is more of the country not under CODE than is. And it's only a problem if a joint comes apart.

As to Texas... last I heard it has the 8th largest economy in the world and had a budget surplus up to just recently and I can't say that it doesn't now. If the state or region you live in doesn't have a surplus, you might want to ask why not. BTW, Texas managed to do that with no personal income tax. And you can't find better roads and services anywhere and it is the second largest state in the union.

As a homeowner and one who likes coordination and fashion ( t shirts and jeans) it would be nice if they could make that stuff in perhaps, a nicer color, like baby blue, or minty green. Then the customers might not complain about the look of their pipes.

 

[Waterwelldude]

I am working on patenting a red striped glue. That when it dries, it will leave a cheerful pink line at the base of the joint being glued.
For the more adventurous customers, a minty green is also in the works.

Just trying to give some of the more colorful customers a choice.



I was just stating the things I have seen where cleaner was used.

Yall sure do get all bent out of shape, when someone has a different view than you do.

Sounds like you might have beeen sniffing it a bit already!

The only purpose of purple primer is so an inspector can see that it was primed/cleaned...it is slightly less aggressive than clear...the use of purple will not make the weld any stronger than clear...in fact when we were first required to use it here it was causing the pipe to slowly back out and it was causing problems...we (plumbers) started mixing clear primer with purple at 50/50 and this solved the problem while leaving a telltale purple stain so inspectors could see it was primed...priming should be done when solvent welding per the directions on the can,thanks cookie, per code...and if the use of purple is required by code, it should be used...

using PVC for compressed air is nuts in my NSHO....

 

[NHmaster]

NH does not require purple primer, but it does require primer and you can buy the stuff in clear. Without the primer, a solvent weld is not completed. The primer cleans and softens the pipe and fitting so that the glue can penetrate both and make what is when dry, a solid piece of plastic. If you are getting a coat of purple that is hard and dry you using too much and not working fast enough.

Now let's end this stupidity because all codes require primer for PVC and the reason tey do is because the manufacturer does.

Good luck on that. Once again stupid reigns supreme even after overwelming evidence in their face...
