"PVC-U pipe

the whole point of pvc cement is to weld/melt the inner/outter layer of plastic and fuse the two toghether,if there was such a gap no cementing would take place.

green glue is for pressure applications,period
You don't seem to understand the design of PVC fittings. All fittings are tapered for an interference fit at the bottom, yes. However, larger diameter fittings have a larger gap near the top, and a more viscous cement is required to fill in said gap. Heavy Duty cements are designed for larger diameter fittings.

Also, please learn how to spell.
Regardless of whether i can use correct grammer or not doesn't matter ,you still understood my post,hence your reply ,I dropped out in year ten to become a plumber im 23 now and have been doing it for the past 6 years, you say i dont have an understanding on pvc fitting design,well thats a crock of 5hit,i can pretty much guarantee that ive glued more fittings together than most of the people on spudfiles,20MM -375MM ,altho i dont know the age/profession of alot of people on here so that statement may not be right.

you dont fill in the gaps of the fitting with high viscous glue ,you use the correct glue for the right application,whether pressure or non pressure.

WRONG,WRONG WRONG :wink:
and if you doubt what im trying to say i dare you to find a reference/document that states otherwise.
ps..good luck :)

I'd tend to agree. Something about the name implies that heavy duty cement is intended for heavy duty.

Thick formula fills gaps in large diameter pipe and loose fitting joints.

Ever think your overtightening the lid/cap?Because through all my years of spudding and plumbing I've never had a container of glue go off on me.

well ill be damned, it wouldnt surprise me tho considering the american's change the english language to suit there own...

but maybe you could find an australia glue the beggs the differ,considering im australia and that's all i have to go from,

ps. that glue isnt avaliable in australia so my statement stands. and 6 years of schooling on the subject tells me otherwise.

RECOMMENDED USES
The All Purpose Clear Heavy Duty Cement is specially formulated to solvent weld up to 6” (150 mm) diameter Sch. 40 aSch. 80 ABS, PVC and Sch. 40 CPVC
nd
pipe.

Seems to imply that this glue is specially forumlated for large diameter fittings.

Regardless of this whole discussion, when stating facts, please state them correctly. IE, 'green glue is for pressure rated PVC only' is only half true. Next time say, "green glue (of a certain brand), when bought in Australia is designed for pressure rated PVC".

And the same for when you say Heavy Duty cement isn't for large diameter pipe and fittings. When it clearly is in America and seems even Australia.

Just make sure you clarify your statements first, afterall the majority of the members are American.

So back to the topic at hand.

The reason my glue is drying up is because i am not tightening the lid enough. So should I clean the threads of the top so that there is no glue on them, and tighten the heck out of it with some pliers, vice grips, channel locks etc.

Am I right?

Most consumer oriented home repair plumbing sections simply don't carry anything in the commercial public works project sizes. When was the last time a suburbanite needed anything over 2 inch in pressure rated pipe. The back yard pool or hot tub plumbing is the biggest pressure application they will ever see.

For this reason the local retailers don't carry the cement for 3-12 inch pressure pipe or metric equivalent. Only commercial supply houses would even stock it.

Go away from residential pluming supply and find the public works size pipe and supplies. When you find the 12 inch or 200 - 300mm pipe you are in the right place.

If they stock water heaters you are in the wrong place. If they stock fire hydrants you are in the right place. :D

@tech considering the above mentioned stores supplly pipe in sizes ranging from 32mm-375mm in plastic am i in the right place ?? thats the biggest size pipe in australia made from plastic (pvc) any bigger an and you move on to rubber ringed pipe or solid concrete sectioned pipe, they also supply oxygen and acetylene which isnt avaliable to the public without an apropiate account, these aboved mentioned shops is what just about every plumbing company in australia use from residentual to comercial building supplys, any civil plumbing supplyers dont use glue so we wont go there.....

Credentials or no credentials, the manufacture that makes the stuff is qualified to provide an application sheet.

I am ISCET certified and work in R & D. There is no certification for cutting edge. We write the certification requirements, review them and publish them. I work with MSDS sheets everyday. I test the limits of materials as part of my job. We have a good idea of failure modes to expect and test to find the limitations and engineer solutions past them.

http://www.iscet.org/

No end user certification is needed to read the manufacturer's instruction sheet. Sorry linking to it and quoting it resulted in an attack on the end user's credentials. The attack is misplaced. If the manufacture screwed up, please state it so this can be corrected.

I did in fact check your credentials. It clearly states;
only a Master Plumber with a valid Certificate of Insurance may offer or contract to perform plumbing work for the general public.
You are qualified to do consumer contract plumbing. You are not qualified to install fireplugs along the highway. When you are qualified in public works and city water systems, please post the license. The other license is for public works.

For the record, I am not a licensed plumber. I don't contract to do consumer plumbing or city plumbing.
