Dippel is the first company to offer a “one stop” source for complete water infrastructure rehabilitation. We are the first lining company to offer dual technologies – epoxy lining of water pipes and structural lining of drain and sewer lines, from a single source. Dippel has an impressive resume of rehabilitating not only drinking water lines and drain pipes, but has rehabilitated mechanical systems such as fire sprinkler systems, heating systems and chiller lines. These technologies from a single source provide our customers with affordable, long-term solutions to pipe failure and leaks while providing the cleanest, safest water from every tap.

  • About Pipe Relining

Metal piping systems begin to deteriorate from the moment they are put into service. Buildings built in the 1950s and early 1960s typically lasted 40 or more years with few incidents of leaks. Buildings built in the 1970s often achieved 20 to 30 years or more of leak-free service. Older pipe systems using stronger grades of copper regularly achieved these life spans even with particularly aggressive water. However, mandatory chemical additives to drinking water since the 1970s is causing pipe failure in above ground and below ground piping systems in as little as 5 to 10 years of service.

Corrosion is often caused by high water temperatures and low pH or high oxygen. As corrosion continues, your pipes will break down and develop leaks which can lead to property damage and health hazards such as mold. Pipe damage can also be caused by poor installation, poor drainage, erratic water flow and metal leaching. While pipe damage may have been resolved with excavation and breaking through walls, floors and through driveways; pipe relining is a trenchless technology that allows us to repair the pipes without doing extensive damage to your property. Pipe lining uses the existing pipe and lines it with epoxy, resin or a new pipe to restore the flow to your home or business. To determine the best pipe relining technology we will inspect your pipes with our video detection units and offer you an estimate. Some of the lining services we provide are as follows.

There are several other common problems that require pipe relining, such as:

Aging Sewer Lines – Most facilities/structures built prior to the early 1970s had sewer lines composed of primarily cast iron and clay. The primary problem seen in these lines is cracking and the bottom of the pipe rusting out.
Root Intrusion – Root intrusion into sewer pipe systems is reported to cause 50% of all sewer blockages. Interference of trees into sewer systems is likely to occur in older systems and in cracked pipes. Factors that contribute to damage include older pipes with joints, shallow pipes, small-dimension pipes and fast-growing tree species. Cost associated with caring for root intrusion in the past has been expensive and it is rarely a long-term fix.
Calcification in Sewer Lines – Over time, calcium deposits from water form a crusted coating called ‘calcification’ which clogs up household pipes and drain lines, especially when hard water is in use. Once pipes are lined with epoxy, calcification can no longer occur because the deposits cannot adhere to the interior walls of the new epoxy barrier pipe.
Ground Movement Affects Sewer Line Integrity – Major seismic activity can cause breaks in sewer lines, but more frequently, minor seismic activity causes cracking and structural damage at the joints. The seamless, “jointless” nature of the PIP method means not only is the existing problem solved, but the new, seamless pipe will avert future problems as well.


Nu Flow’s patented, Cured in Place Pipe (CIPP) system creates a protective, structural pipe inside the existing host pipe system, without digging or destruction to buildings or landscape. Our CIPP is a seamless, jointless, pipe-within-a-pipe that is used to rehabilitate deteriorating sanitary drain and storm sewer lines, including mechanical systems, with minimal disruption. CIPP Lining is a lot like epoxy lining in the installation and preparation. With CIPP Lining we saturate a liner that is cut to the exact length of pipe that needs to be repaired. We will pull the liner in place and allow it to cure using an inflatable liner. We can also install the liner where we skip over connections to make the process less time consuming. CIPP typically requires two points of entry to place the liner; however, placement in shorter lengths of pipe is accomplished by using a push-rod system.

CIPP is inherently environmentally friendly. An enhanced wet-out process helps us reduce waste during installation. Less equipment on the jobsite means less energy usage and less emission.

A crucial transition has been the adoption of “inside” underground lining applications for repairs to “outside” pipes where, in the past, those repairs were managed as external trenchless repairs requiring external solutions. CIPP restoration is a non-invasive procedure that uses epoxy inside a liner to create a new pipe inside deteriorated host piping systems and can span missing sections of pipe. CIPP is a long-term solution for leaks and breaks, blockages, root intrusion, calcium build-up, water damage, mold, sewer backups and increases flow capacity.


Epoxy lining restoration of plumbing, structural pipe, and mechanical systems is a non-invasive process that uses epoxy to coat the inside walls of pipes without destruction to interior or exterior surfaces of building structures, hardscape, or landscape. Epoxy lining is used not only as a long-term solution to prevent corrosion and leaks, but is commonly used as a preventative tool to preserve the life of existing piping systems. Valentine’s patented epoxy lining system is applicated regularly in pipe diameters of 1/2″ to 12″.

Lining is an eco-friendly solution that creates no waste for landfills or for recycling and generates no carbon emissions during manufacturing. Lining prevents toxic heavy metals from leaching into drinking water and prevents leaks and breaks in pipe systems that contribute to water pollution and cause billions of dollars annually in water damage. Revolutionary, green technologies such as epoxy lining have replaced temporary, outdated pipe replacement methods as an eco-friendly trend that efficiently and economically controls pollution of our water sources and helps conserve valuable water supplies.

Some benefits of epoxy lining include:
1. Safe And Durable – Valentine’s epoxy is UL certified safe to NSF/ANSI Standard 61.
2. Cost Effective – Pipe lining is as much as 50 percent less expensive than traditional pipe replacement costs such as repiping.
3. Minimal Downtime – A repiping job that would normally take a full 6 to 8 weeks can take as little as two weekends for Valentine to complete.
4. Minimal Disruption and No Occupant Displacement – Valentine’s pipe restoration process is quick, quiet, non-invasive, and requires no displacement of a building’s occupants.
5. Versatility in Applications – Epoxy lining can be performed in any metal pipe in any building, structure, or environment, above or below ground.


Pipe capacity restoration includes the use of hydro, mechanical and pneumatic equipment to clean out existing piping systems. Valentine has a variety of technologies available to solve the pervasive problem of pipe corrosion. Over time, water and other liquids within pipes lead to a buildup of corrosion or other materials that obstruct water flow and lead to other problems. Valentine’s solutions effectively restore pipes to their original inside diameter. This process is completed before applying an epoxy coating or installing a structural liner within the pipe.
