Bathroom Remodeling

Repiping is a process of installing a new quality  repipe system. This process usually includes removing old readily accessible pipe and then installing the new plumbing system. Included in the process is the installation of new  PEX "a" tube, or USA type "L" copper, properly strapped and secured. Install Kwik turn 1/4 turn ball Valve type water stops. Install new stainless steel water supply lines. After the new piping system is installed the water is turned back on. Then  the system is pressure tested, and then flushed out. The re-piping process takes 1-3 days to install the new piping system. After that there will be some required wall or ceiling patching.

Epoxy Paint Coating of Pipes ?

Leaking Epoxy Painted Pipes? Epoxy Coating of water pipes? Epoxy Coat. Leaky Flow? Thin Coat? Duraleak? Curaleak?
Un-uniform Epoxy Coat Leak? Time to Repipe because the Epoxy Coat did NOT Cure a  Leak? That Epoxy Pipe Coat can either be too Thick or too Thin. Sometimes it clumps sometimes it does not stick at all. What happens if the Epoxy Pipe Coat process does not work the first time? Can you use two coats of paint? NO!! You need to Repipe - Repiping is a Permanent Solution To Leaking Pipes - Slab Leaks - Soft Copper Leak - Leaking Water Pipes - Rusty or Worn thru pipes -

Epoxy Paint Coating of Pipes is a Hopeful Joke and is NOT a solution to Leaking Pipes in the Slab - The basic process for Epoxy Paint Coating is to attempt to completely and uniformly sandblast the inside of the pipe to a level of being "clean" no real way to know when clean is clean. After the sand blasting, there will be an attempt to apply a uniform and continous coat of epoxy paint inside the pipe. Ever wonder why most Epoxy paints only have a five- ten year warranty?

That paint job inside of your pipes will only have a limited and partial warranty - Maybe only one year by the manufacturer and a partial 5-10 year warranty by the installer. Every Epoxy Process and company and  is case by case - Epoxy Pipe Coating Process is NOT proven to be able to fix existing leaks that may or may not yet exist - If the Process does not Work you must repipe - When Epoxy leaks you must properly repipe. The Epoxy Process is not warranteed or gauranteed to work or be effective - Only after the Epoxy Coating Process is complete can the System be tested and then you receive a hopeful 5-10 year warranty.

During the "sandblasting" there will be an attempt to completely "clean" the inside wall of the pipes, often during this cleaning and sandblasting process the pipes can be over cleaned, worn thin and worn thru. It will be a guessing game and a hope full wish that the pipe are not worn too thin. There is no way to know what the thickness of the existing pipe will be before, during and after the sandblasting process.

Before, during and after the sandblast cleaning of the existing pipes there is no positive promise that the Epoxy Paint Coating will even work - Most Epoxy Coat Pipe Painting companies Do NOT warrant that their Epoxy Coating will even work or solve pipe problems. Even if you start the process with no leaks. During the sandblasting process , the process can wear thru the pipe and create many new leaks under the slab where none existed. If this is the case you will need to repipe as you should.


Is there evidence to suggest concern about epoxy safety?  

Prior to its use in pipe-lining, epoxies have served as barrier coats in water storage vessels. This process is 

much simpler than lining a pipe, but the process and chemistry are still complex, and there are many 

opportunities for problems. Failures in substrate preparation, e.g., insufficient drying, errors in mixing of 

ingredients, etc., may lead to problems in the finished coating, some of which can affect barrier integrity (6). An 

incorrect formulation could lead to incomplete curing and the potential for chemicals to leach from the coating 

into drinking water. 


Water contamination from some epoxy pipe-lining materials has been found in independent laboratory tests. 

Alben el al. found that methyl isobutyl ketone and xylene leached from epoxy-coated test panels and from 

epoxy-lined water storage tanks [cited in (5)]. Hazardous volatile organic chemicals, among them benzene and 


 ANSI – American National Standards Institute,  NSF – National Sanitary Foundation 

 For example, with the USEPA listed organic contaminants, the ANSI/NSF 61 standard requires that contaminant 

levels be no more than one-tenth of the maximum level allowed in water by the USEPA or other regulating authorities. 

xylene, were found to leach from epoxy into water at levels above the acceptable maximum specified by US 

and Canadian regulations, and some of the tested materials were ANSI/NSF 61 certified (7). The Satchwill 

report concludes, “It was found that these linings can cause significant contamination of the drinking water” (7). 


The US military services have used epoxy pipe-lining since the 1990’s to deal both with high corrosion 

environments aboard ships and for pipe-rehabilitation to avoid lead contamination in drinking water (8) 

(9). In 1992, the Naval Research Laboratory’s (NRL) coating development program was delayed and 

forced to shift to new formulations. Changes in federal regulations that year tightened restrictions on 

one of the existing coating components, a toxic, carcinogenic epoxy hardener, 4,4'-methylene dianiline 

(10). While the main concern was safety of the epoxy workers, the components of some epoxy systems 

used for pipe rehabilitation clearly pose a potential risk for toxic chemical contamination.  


In the United Kingdom (UK), epoxy-lining for pipe rehabilitation began in the 1970’s and became common- 

place in the 1990’s (11). Concerned that the aging of rehabilitated piping systems might pose health hazards, 

regulators commissioned a study. The 2007 report to the UK Drinking Water Inspectorate concluded that, 

“...any leaching from the pipe linings is at a low level” (11). Pipes lined with five UK-approved epoxy 

formulations were surveyed. The report notes that, “Evidence of leaching of 4-t-butylphenol (4-TBP) from 

Resin C was found...”, however, the concentration was quite low (in the part per billion range). While 4-TBP is 

an irritant, it is not otherwise believed to present a significant health risk.3 It is important to note that in the UK, 

in-place epoxy-lining can only be performed by approved contractors.  


Some epoxy materials used for pipe-lining are formed from the controversial bisphenol-A (BPA). 

Repeated studies by the US Centers for Disease Control and Prevention have detected BPA in the 

urine of 93% of tested individuals (age 6 and above) (12). BPA is an endocrine disruptor, and there are 

significant concerns about the safety of chronic exposure to low-levels in food (13). While pipe-lining 

suppliers say their products are safe, vendor documents acknowledge that there is some risk for 

bisphenol-A exposure above ANSI/NSF 61 certification levels when lining installation procedures are 

not rigorously followed (14). 


Most vendor websites provide little detail on the chemical formulations of their epoxies. Even worse, there may 

be serious inaccuracies, for example, the Cleanncoat site states, “...CleanncoatTM does not use any chemicals 

in the pipe restoration process. We use three elements: air, sand, and epoxy” (15). There is no doubt that 

chemicals, and in some cases hazardous ones, are used to produce epoxy pipe-linings. Any claim to the 

contrary should be a red-flag for potential customers.

  Most risk assessments take an exposure value from an animal study (dose in mg/kg-bw/day) and divide it 

by several uncertainty factors to arrive at an acceptable dose in humans. This value is what is shown here as 

an “intake limit” and is what is compared to an expected/estimated exposure value in a risk assessment. 

BPA-based materials are pervasive in the U.S. economy. Apart from food-related uses, 

they are used in automotive and other transportation equipment, optical media such as DVDs, 

electrical/electronics equipment, construction, linings inside drinking water pipes, thermal and 

carbonless paper coatings, foundry casting, and elsewhere. A handful of companies manufacture 

most BPA, as well as most BPA-based polycarbonate and epoxy resins, but numerous companies 

process BPA-based materials into final goods.

Two-component epoxy know what epoxy glue is, right? It comes in two containers. You mix component A with component B in a precise ratio, stir them together and work like a dog to do the job before the epoxy hardens in the mixing container. If you were to thin it out some and add colorant to it, you'd have two-component epoxy paint.

What is bisphenol A?

Bisphenol A (BPA) is a widely produced chemical used primarily for the production of polycarbonate plastics and epoxy resins. More than 6 billion pounds of BPA are produced and used each year for this purpose. The use of this chemical is so profound that it was detected in the urine in 93% of the population over 6 years of age. The study did not include anyone under 6 years of age, so the level in their urine is unknown.

Polycarbonate plastics are typically hard and clear and are marked with the resin identification code number 7. As mentioned previously, the number 7 is considered the "other" category and includes chemicals other than bisphenol A. Nalgene water bottles were made with BPA until recently. They are being voluntarily pulled from the shelves and replaced by bottles that are BPA-free made with a relatively new plastic called Tritan copolyester. Other sources of polycarbonate are food and drink packaging, including infant bottles, toddler sipping cups, tableware, and food containers. Epoxy resins are used to line metal products such as canned foods, bottle tops, and water supply pipes.

Start the right way - Repipe your Building - Repiping is a Warranteed and Gauranteed Piping Process - PEX and U.S.A.
Hard Copper has 25 - 50 years warranties. Soft Copper should Never be used except for emergency repairs or HVAC.

Epoxy Pipe Coatings are good if you want to paint your garage floor - or just want to buy time. If you want a 

Once you wear thru the pipe the only proper way to fix the worn thru Epoxy painted leaking pipe is to repipe. Do you really want to drink Epoxy Paint Coating as it wears away inside of your pipe? What does Epoxy taste like? Is drinking Epoxy good for you? How much Epoxy do you want to ingest? After 5-10 does the Epoxy disolve faster? What happens when Epoxy fails? How does Epoxy fail? Can the water get inbetween the old existing pipe and the Epoxy Coat? What is the leaching rate for Epoxy over time?  Epoxy Coating of drinking water pipes has been practiced since 2002 - Epoxy is a Glue/Paint that needs to Cure, that Cure process is not always Durable, or cures any leaks and the process does not always let the water Flow. 
Basically the epoxy paint is blown in with high pressure air. 

Pipe Sizing 

Many existing structures that were cheaply build used soft copper under the slab foundations. Many times the pipes are undersized. As a general practice a 1"main feed line can feed upto a 3 bathroom house. When there are over 3 bathrooms the main line should be upsized to at least 11/4". If there are extra fixtures; Roman tubs, dual spray showers, bidgets, double sinks, laundry sinks, bar sinks, two or more dishwashers the main should be upsized.

Some 4 bathroom homes are undersized and have 1" lines, if epoxy paint  is applied to the inside of a pipe it will reduce the inner diameter 1/8" -1/4 of an inch in a best case senario. reducing the inner diameter of existing undersized pipe in not recommended and will restrict water flow. How thick or thin should that Epoxy be to be effective?

 Reminder fact- When sandblasting the pipe, often the pipe is almost or completely sandblasted thru. The Epoxy Pipe Coat covers up those thin spots, but for how long? Sometimes Epoxy cannot work at all. Sometime Epoxy last for days, weeks, months, and years.
