Schedule 40 PVC piping systems have been successfully used for pressure and drainage systems in industrial, residential, commercial and agricultural installations. PVC Schedule 40 is ideal for applications where transmission of liquids or materials does not exceed 140^oF. The physical and chemical properties of PVC Schedule 40 makes it ideal for the transmission of potable water and many chemical solutions. PVC Schedule 40 has a smooth interior surface that minimizes head pressure loss through friction, minimizes rust and oxidation, and is generally impervious to scaling or contaminant buildups. Systems are not adversely affected by environmental agents and buried systems are not adversely affected by normal soil contaminants.

The life expectancy of plastic systems far exceeds that of metal systems and required maintenance is simpler and less costly. PVC Schedule 40 fittings are not recommended for use in compressed air or compressed gas systems.  Carry stocks PVC Pipe and Fittings in 4", 6" and 8" sizes.  Standard fittings include: female adapters, male adapters, clean-outs, 45 and 90 degree elbows and 4" to 6" increaser couplings and 6" to 8" increaser couplings.

The Waterman Model PC-30 in-line Swing Check Valve is designed to offer a dependable low pressure swing check valve for the pumping industry. The basic unit can be supplied with a variety of optional features to fit particular applications, including qualification as back-flow prevention against flooding the wet well or recycling water in the wet well.

This valve is constructed with a high strength cast-aluminum body and features a tight-sealing, nitrile rubber seal. Hinge pins are stainless steel and operate in non-metallic hinge bushings with lubrication fittings. All models (4", 6" and 8") are fitted with torsion springs on the covers for extra quick closing to prevent water hammer. Mechanical joint compression couplings are provided on each end to allow the unit to provide the additional function of a flexible coupler in many installations. Flanges are available upon request. Units may be fusion epoxy coated inside, including hinge arm and disc for total corrosion protection.

These flap valves are designed for use on pump discharge lines and other pipe end closures to prevent entrance of back water. These valves are furnished with a variety of frame styles to fit most installation needs. A 7-1/2^o inclined seating plane is used to ensure that the valve will not "hang open" from slight pipe sagging or off grade. A positive stop prevents over opening.

The compression model uses time proven wedge type seals to install quickly and easily on plain end standard steel pipe. This model is standard with a cast iron frame with machined seat face and a cast iron cover with a resilient neoprene rubber seat face. Follow ring is cast iron with rubber wedge gasket and plated steel draw bolts.

Valves are available with aluminum covers and neoprene seat faces where extra sensitivity is desired. Taper setting collars can be provided as an aid for installation on concrete pipe.

These gates are used to prevent back-flow of water into the drainage system, keeping the drainage system from flooding. They are constructed with quality materials and have a special finish for longer life.

Quick Disconnects are used for quick and easy pump removal from wet wells and Capsule Pump Stations. The disconnects are attached to the discharge plumbing and may include cams for easy disconnection of the discharge plumbing. There are two styles available and both come with female or male threads.

All 4" and 6" Disconnects are manufactured to specification MIL-C-27487. Conformance to this specification allows complete interchangeability. Couplings "not interchangeable" in the industry are 8". No standards were established by the government for this size. All aluminum couplings are furnished with bronze cams and Buna gaskets as standard. All Stainless Steel couplings are furnished with stainless steel cams and Buna gaskets as standard.

4" Quick Disconnect couplings are designed for working pressures of 150 psi. 6" Quick Disconnect couplings are designed for working pressures of 75 psi. Burst or failure can occur if this pressure is exceeded.

These Quick Disconnect Couplings are an alternative to the aluminum and stainless steel disconnects. These couplings are available in 4" only.

These flexible couplers are manufactured of specially formulated elastomeric PVC. They are used as highly effective PVC pipe couplers. This material is highly resistant to caustic chemicals, ultraviolet rays, fungus growth and normal sewer gases. They are leakproof, rootproof and seal against infiltration and exfiltration. They also flex with earth movement, maintaining the integrity of the seal. They feature rustproof Series 300 stainless steel bands including screw and housing to assure easy installation and a positive seal.

These couplers produce a strong, reliable connection every time. And no special tools or fittings are required. Because of their quality and ease of installation, these couplings have found wide acceptance among sewer and plumbing contractors and municipalities.
