Make sure the joints fit snugly and use the proper applicator. Apply an even coat of cement to the outside of the pipe and the fitting to be joined. Avoid gaps and puddles. Pipe ends must be coated entirely twice and wet before assembly. Hold together for 30 seconds.
Recoat if dry. Hold the pipe and the fitting together for 30 seconds to prevent the pipe from pushing out and wipe off any excess cement. Allow 15 minutes for proper handling and 2 hours for a full cure. Test with up to psi. Do not test with air. Be advised you must complete steps 2 and 3 within thirty seconds for a secure joint. Pipe ends must be completely coated twice and wet before assembly. Remove any excess cement and do not disturb joint for at least 10 minutes. After that, leave joint for 24 hours to achieve full strength.
Only water pressure test after one hour. Author Recent Posts. Pipe made of polyvinyl chloride, commonly called PVC, is used in a variety of residential applications, from plumbing systems to a host of cool craft projects such as DIY racks, organizers, and even furniture. Joining a pipe to a pipe fitting requires specially formulated primer and cement—no ordinary adhesive but a chemical solvent that melts the surface of the PVC and then quickly re-hardens to fuse the pieces together.
The result is an airtight, leak-proof bond similar to what you get with welding metal. The process involves applying primer to the outside of the pipe and the inside of the fitting, which cleans and preps the PVC.
After about 10 seconds, you next apply cement to the same areas, then insert the pipe snugly into the fitting and allow the cement to set. There are different kinds of cements and primers on the market formulated for various types of plastic piping.
Read labels carefully and be sure to select cement made specifically for PVC. Be aware that one type of pipe cement you may see on the shelf is designed for CPVC chlorinated polyvinyl chloride pipe, which is similar in name but not an acceptable substitute. Hercules makes a heavy duty long-working-time PVC cement, shown above, No. Schedules 40 and The Slow Set versions Hercules makes both the gray and a clear slow set PVC cement will give you about twice that, or 1 to 2 minutes of set time.
You might call for a more-clear answer: contact Hercules customer service at the phone or email we give above. That product is described below. Weld-On has a chart of Weld-On R solvent cement average set and cure times that gives an idea of the effect of temperature on set time.
So if you can do your gluing on a cool morning you'll have more set time to adjust your fittings. And as larger pipes all have longer set times a 15" or larger PVC pipe needs 4 hours to 48 hours depending on temperature we can infer that the more-generously the glue is applied the longer should be the set time.

Quoting from the company's website Zurn was founded in in Erie, PA. It originally manufactured a patented backwater valve, and it now manufactures and distributes one of the largest plumbing products packages in the world! After denying Zurn's motion to strike the expert testimony, the district court2 granted the homeowner requests for class certification for their warranty and negligence claims, but denied it for their consumer protection claims.
Zurn appeals from the district court's certification order. We affirm. A Review", Human and Ecological Risk Assessment: An International Journal Volume 14, Issue 4, , Abstract: Plastic pipes used to convey hot and cold drinking water are synthetic polymers containing numerous additives that enhance durability, impact strength, and toughness, and resist material degradation.
Although some research studies have been conducted to evaluate the type and levels of chemical substances migrating from polymeric materials into drinking water, the potential adverse health effects associated with these compounds in potable water have not been described.
This review evaluates the literature on the occurrence of regulated and unregulated substances in drinking water related to the use of plastic pipes, characterizes potential health hazards, and describes uncertainties associated with human health and exposure in need of further research. Contaminants are measured in the distribution system, not at the tap where human exposure actually occurs. For increased health protection, it is important to identify compounds that migrate from plastic pipes into drinking water and to better quantify human exposures and health hazards to these substances and their degradates.
Whelton, Andrea M. Dietrich, Daniel L. Dietrich, Chair Daniel L. Gallagher Marc A. Edwards Brian J. Love James M. Tanko, April 2, Blacksburg, Virginia. Abstract: While more than years of research has focused on removing acute and chronic health threats from water, substantially less study has focused on potable water infrastructure and water quality deterioration, monitoring technologies, and relationships between water taste and consumer health.
These knowledge—gaps also prevent infrastructure managers from producing drinking water that optimizes mineral content for both water taste and health benefits, and employing a monitoring tool capable of immediately detecting water contamination or equipment failures. Research was conducted to address these challenges using analytical chemistry, environmental engineering, food science, polymer chemistry, public health, and material science principles.
This work was enhanced by collaborations with sixteen American water utilities and the National Institute for Standards and Technology. Research results are unique and provide important scientific contributions to the public health, potable water, and material science industries.
Outcomes of this work have domestic and global significance, and if engaged, can greatly improve public health protection, potable water infrastructure operations, water quality, sustainability, and regulation. The odour of water in contact with plastic pipes was assessed according to the quantitative threshold odour number TON concept.
In addition, a range of esters, aldehydes, ketones, aromatic hydrocarbons and terpenoids were identified as migration products from HDPE pipes. Several of the migrated VOC were not identified. Migration tests of PVC pipes revealed few volatile migrants in the test samples and no significant odour of the test water. Whelton, Ph.
