I like it.......I also like any excuse to use duct tape.
Good Idea.

yea I get the small cans of PVC glue and fine they usually don't last beyond 1-2 uses before they dry up.

Never had a leak, weak joint or failure yet. The shampoo bottle says I'm supposed to repeat the application but I ignore that too.

They want to sell more shampoo.
The primer is a part of the PVC bonding process. Not the same thing.
Eh, your stuff....

Store the can upside down. I've been using the same can of glue for around 5 years now. I don't know why, but it does work.

I will have to try that, last time I needed to glue some pipe (1 joint) the damn stuff had dried up

You really only need the primer before the valve. On the manifold and supply lines.
After the valves, its not under static pressure anyway. This advice from my Board Certified Landscape Architect brother in law.

From what I recall, PVC cement was around long before PVC primer and as a kid working for my FIL, we made thousands of joints without it. From what I can see of it, its a solvent that will de-grease and clean the pipe and sockets and it's something inspectors look for (that's why it's colored) but you can make PVC connections just fine without it but we always did wipe the pipe and fittings with a clean rag to make sure there was no debris in the joint

Definitely helps from knocking them over too.

I use the duct tape trick also, my local menards sells a set of primer and glue in a cardboard box for cheaper than the glue and primer seperate. The box was nice because it works like the duct tape but usually fell apart after 1-2 times using it so started using duct tape.
Primer for pipes is sort of like primer for paint, it isn't "needed" but it helps. The primer cleans and helps the glue bond to pipe. I always use it just like I almost always use paint primer. I want to do all I can when it comes to keeping my **** inside the pipes and not leaking.
I also use a channel locks to tighten the caps good when I store the glue. When they come from the store they take a pliers to open so I use a pliers to close. Also never leave them in cold temps, I always store mine inside.

The primer is essential for any decent work and required by code for pressure applications. It is also required by the manufacturer of the glue for PVC pressure applications. You are supposed to go around the pipe and socket repeatedly with the primer (it's acetone) to soften the pipe (you check by scraping with fingernail initially and then you develop experience) to prepare the pipe for the glue. It is not a cleaner. It is a softener to facilitate the solvent welding process.
I've heard lot's of BS as to why you don't need it but it all comes down to laziness and whether you are the type of person of likes to do things right or half ***.

Cough....cough...ahem.... Have we got someone who is a little judgmental here or what? I call BULLSCHIT. You're making the use of PVC primer a character issue, it's NOT.
Because I, and a lot of others do not use primer in non pressure applications does NOT make me "lazy"
nor am I "not care(ing) about doing things right" or a "half ***". How about some decaf, huh Mark?I've probably done literally thousands of PVC pipe joints without primer and not one of them has ever come apart. I've done hundreds WITH primer (in constant pressure applications) and none of those have come apart either.
To "Professur" who said he'd never used primer: If you're fixing a sprinkler in your backyard? You don't need primer. NOTHING is going to happen if you make a clean square joint and follow the instructions to twist the joint as you make it.

I had occasion to reroute some plumbing at the cottage recently. I took the challenge and bought a jar of primer to give it a try. Everything on the label suggested that it's primarily for cleaning the ABS .... something I've always done with sand paper. I did note that using it did sort of pre-soften the ABS ... as noted by the residue on the glue brush. The working time also seemed much longer. Going from the usual 4 seconds to about 20.
It should be noted that I've never used ABS or PVC in a pressure job.

ABS doesn't get primer. Neither does electrical conduit.
Primer is definitely for softening, not cleaning, so I have no idea what you had. There are cleaners but I have never seen them and truly no one uses them with the primer. I would not use sandpaper either.
For the poster who is so confident in his pipe work, how do you know you've never had any leaks. I always get a kick out of people that say stuff like that. Any plumber or person who does enough plumbing has leaks. For example, I have had many leaks with NPT fittings with both water and gas. I've had a solder joint leak (although I could tell it would leak when it wouldn't take the solder right) and I've had a PVC joint blow apart. Did you pressure test all the underground sprinklers before throwing dirt on top? How do you know that aren't all leaking underground. If above ground, are all those thousands at your house so that you would know if they were leaking?
I like to watch these types of video, then you know you are doing it right.

I had to look at what we are using at work and we use clear cleaner not primer. It softens the pipe pretty good. We do not use primer (I though that primer and cleaner is the same thing... wrong.) Even at that we rarely have a problem, and when we do its because we try the turn water back on to soon.

Do you work as a plumber? Because you know that the plumbing codes require primer, not cleaner, right? Basically, the plumbing codes require that you follow manufacturers' directions, and the directions require the primer.

I'm pretty sure it said primer on the can. I'll be heading up there soon, so I'll take note of the brand and exactly what's written on it and report back. I do know that both jars were the same brand.

Municipality... (I dont even think they know they are doing that wrong) At home I used the purple primer.

I've heard a lot of people say that Christy's Red Hot glue doesn't need primer, that it has the primer in it (doh!), but if you look at the can it says primer required. My can of Weld On Wet N Fast (my favorite) says in bold print, "THE UPC requires purple primer."
All plumbers use it because they can't afford to cut corners and risk ruining someone's house with a flood. The place you see the skimping is with the landscape guys.

Right from oatey's website:
1. What is the difference between pipe cleaner, primer / cleaner and primer?
All pipe surfaces should be thoroughly cleaned with pipe cleaner. The cleaner is formulated to remove surface dirt and any oil or grease that exists on the pipe from the manufacturing process. Primer/cleaner and primer contain more aggressive solvents and will soften the pipe surface to allow the solvent cement to penetrate more effectively. Primer is often required by plumbing code and sometimes a purple colored primer (purple primer) is needed.
Here is the description for the purple primer:
• Removes surface dirt, grease and grime as well as softens the pipe surface to allow a fast, secure solvent weld.
• For use in areas where plumbing code calls for
requirements. verification that a primer has been used.

I was putting in a pocket door in a friends finished basement two months ago. Went to put the trim on and finish up when his wife asked me about the carpet being damp, we had a ton of rain in the days before. So we decided to start cutting the drywall back and see what we could find. We cut out the drywall for about ten feet and found where the water was coming in. Long story short is one of the walls we pulled out was a bathroom wall with that had about 10" of space between it and the outside wall for the main stack. The main stack was PVC to the floor which was old cast iron. When whoever plumbed this they had a small leak and never noticed it and closed the wall up. Something that wasn't caught for probably ten years, and we only caught this due to the rain causing water problems in the basement.
No purple primer used by the guy that did this, and he probably said he never had a leak also. When really he did, just wasn't big enough to be found. The purple primer cleans oils/grease off and softens the pipe to allow a solvent weld, not just glueing two peices of pipe together. In my opinion the primer is a quick and easy step to ensure that you are doing everything possible to make a leak free connection. I don't see any reason not to use it.
I can weld threw rust and it will probably hold. But I clean the rust and mill scale off where I am going to weld to allow the best penetration possible and not have any contamination in the weld.

Not all primer is tinted. The stuff we use at work is clear. Local code doesn't require the tint. Without the tint, the Joints appear cleaner to the homeowner.
So not seeing the purple doesn't mean Primer wasn't used. They may have used the clear stuff.
There is also a 1step PVC cement that doesn't require a primer on pipe smaller than 6". Its expensive for one can, but still less than the Primer and Cement combined cost.

I have never used primer. The can of stuff I use is red label and doesn't say anything about primer even. Works on ABS, PVC, conduit, etc.
I tried to pull apart a joint I mess up on a while back. I'm talking stuck it together and maybe 5 seconds later did an "oh ****" and tried to pull it apart. I had to cut the pipe!

I never used primer 20 years ago, but about 8- 10 years ago I was doing a job and got a few leaks that cost a few trips to the hardware for new pipe and fittings.
I have used primer ever since and will continue using it. A bottle only costs what a few fittings do so it's cheap insurance for having leak free joints if done properly.
Nothing worse than doing a job twice, and having to pay for it twice as well.

Over here in Australia the primer is pink and the glue is blue.

I've done lots of PVC piping. Started off not using primer, then learned how to do a better job and started using it. Since it cleans and softens the PVC, it makes the joints stronger, the bond tighter, and lets me sleep at night that i did it the correct way.
If you don't have the time to do it correctly, then wait until you do....
I still have plenty of unprimed PVC I did long ago that have held up, but i like to do things a little better than I did a few years ago. Give me a sense of growth and maturation.

Good tips....I actually have some plumbing work in the home coming up shortly.
I'll try the "upside down trick" with glue can....they always dry up on me.
