Our warranty varies by product. For complete details, take a look at each individual product’s page. There you will find individual warranty information on the technical documents (usually found in the Installation Manual). 

Yes, all Mainline Solvent Cements & Primers are Low VOC. VOC stands for Volatile Organic Compounds which are emissions from materials. Low VOC products contribute to cleaner air. The requirements for "Low VOC" have been established by the South Coast Air Quality Management District, ("SCAQMD"), an air pollution control agency for southern California, that sets strict emissions control requirements, (Rule 1168/316A). Many other states have adopted SCAQMD Rule 1168/316A emission limits and/or similar limits for solvent cements and primers.

Identify the parameters of the particular application: Pipe material – PVC, CPVC, ABS Schedule or SDR of piping – Sch.40, Sch.80, SDR21, etc. Pipe diameter Working pressure of piping system Ambient temperature at the time of installation Temperature of media conveyance within the piping system Type of media being conveyed within the piping system – water, specific chemicals, etc. Other variables which may affect application and/or piping system Consult your local sales representative for recommendation.

Yes. CPVC solvent cement technically will work on PVC piping. However, we recommend that the correct Mainline primer and PVC solvent cement for the particular application should be used. Please note that PVC solvent cement, because of temperature limitations, is not recommended for CPVC piping.il.

No. The Mainline primer must be wet and fluid. The purpose of the primer is to soften the joining surfaces of the pipe and fitting allowing proper penetration and dissolution of joining surfaces prior to Mainline solvent cement application. This step is specifically recommended for large diameters, PVC Schedule 80, CPVC piping and cold weather installations.

No. For 4" and larger diameter piping, we recommend the use of 4" swab to apply our primers and solvent cements. A can dauber is appropriate for use on pipe diameters that are approximately twice the size of the dauber diameter.

No. However, we recommend the use of primer on all PVC piping systems. Some Mainline PVC solvent cements for irrigation piping can be used without primer on non-pressure systems if local codes permit.

Mainline primers, PVC and ABS solvent cements: 3 years shelf life Mainline CPVC solvent cements: 2 years shelf life.

All Mainline primers and solvent cements have expiration dates imprinted on the outside of the case boxes and the manufactured date imprinted on the bottom of each can. The shelf life is also stated in the product bulletin of each Mainline product.

Mainline offers 11 different types of wax gaskets from a regular 4" ring to a deep 3"- 4" ring with flange & brass bolts or a urinal wax gasket.

Mainline Epoxy Putty can be used in 1001 applications providing permanent repairs to many surfaces including metals, wood, glass, concrete, ceramics and numerous plastics. One hour after mixing, Epoxy Putty can be drilled, sawed, sanded, filed, tapped, machined or painted and is a general purpose epoxy putty.

Mainline Dark Cutting Oil is used on speed thread cutting machines & Light Cutting Oil is use for hand threading.

Instead of checking for a gas leak with a match, use Mainline’s liquid Leak Detector. After applying Leak Detector directly from the container, large bubbles will appear if gas is escaping. It may also be used to find leaks in air, refrigerants, CO2 and most other gases.

Mainline finishes are incredibly durable and lock in Mainline’s rich finishes for years of trouble free enjoyment. Our Brushed Nickel is protected by physical vapor deposition or PVD finish. Our Oil Rubbed Bronze is protected by a durable powder coat finish.

For best results, simply use warm water and a soft cloth to clean the finish. Gently dry buff the surface with the soft clean cloth and be sure to avoid ammonia-based cleaning materials, as well as bleach and other harsh detergents.

Mainline faucets are equipped with precision high quality washerless cartridges to maintain drip-free flow control. For optimum performance and to honor warranty requirements, please insist ONLY on genuine Mainline branded replacement parts.   

Absolutely! The valves are back-to-back capable by turning the cartridge 180 degrees.

Pressure-balance valves are designed to protect bathers from sudden changes in water temperature and especially from surges caused by flushing of toilets, etc. Pressure-balance valves are required by code in most areas of the country for new construction.

All Mainline parts covered under warranty are free of charge for the first two years. There may be a small charge for parts not covered under warranty. Contact us for details: CustomerService@MainlineCollection.com

Routine cleaning with hot water and soap is important. For mild stains or light scratches, we suggest a mildly aggressive cleaner such as Shiny Sinks Plus® or Flitz®. To remove stubborn stains Comet®, Ajax®, BonAmi® or BarKeeper’s Friend® work well but always rub in the direction of the grain. Always rinse thoroughly and wipe dry after cleaning.

No! Never use steel wool, metal scouring pads, steel brushes, etc. as they will leave behind residue that can cause a rusty discoloration.

Mainline sinks use top quality stainless steel that does not rust. However if your water has a high iron content, a brown surface stain can form on the sink giving the appearance of rust. Also, iron particles from metal cooking implements or steel wool can bond to the surface of the sink and cause rust spots. To remove this surface rust, use a small amount of a recommended cleaner and rub in the direction of the grain. Always rinse thoroughly and towel dry.

Mainline uses top quality Type 304 stainless steel, but any stainless steel sink WILL scratch with use. As the sink ages, scratches will blend into the surface and become less evident.

The quality of your water can affect the appearance of you sink. Iron or mineral content in your water can leave surface spots or a film. This can be removed with a soft cloth, warm water and dish soap. For removing heavier residue, vinegar and water may be used. Always rinse thoroughly and towel dry.

Gauge is the thickness of the stainless steel… the lower the number, the thicker the stainless steel. 18 gauge is thicker than 20 gauge. Mainline uses top-quality type 300,301 and 304 stainless steel. Mainline undermount sinks are all type 304, 18 gauge. Mainline top mount sinks are 18, 20 or 22 gauge.

Brushed satin is a rich, deep finish produced from meticulous machine and hand-finishing resulting in a beautiful, very durable surface that holds up well over time.

Undercoating is a spray protective finish applied to the bottom of Mainline stainless steel sink bowls. It absorbs sound, insulates against condensation and helps maintain water temperature.

Absolutely. Stainless steel will easily stand up to the thermal shock of boiling liquids followed by icy water without any damage.
