How much does it cost to repipe a house?

Every homeowner should know that pipes wear out over the years. The pipes gradually corrode, rust, and decay. Unless you replace plumbing, you are eventually going to get leaking pipes. In the worst case, neglecting plumbing problems could turn into flooding in your house. To fix this you need to spend thousands of dollars. Fortunately, the plumbing disaster is not inevitable. You can prevent it in your future. From this Amco Plumbing’s article you will know how to understand when it is time to repipe house, how the procedure is done and how much it costs in San Diego.


How to understand that you need to repipe your house?

Replacing the plumbing system in a house is considered a complex procedure for both the plumber and the homeowner. It usually requires cutting off walls and floors so that the plumber can get to the pipes. For this reason, repiping is carried out only in case of emergency. There are a number of signs that indicate that pipes need to be replaced, including:

  • – multiple pipe leaks;
  • – the unpleasant smell of rotten eggs in different rooms in the house;
  • – poor water pressure – it comes in a thin stream from any tap in the house;
  • – strange and unpleasant taste of water;
  • – red, brown, yellow or greenish water comes out of the taps;
  • – increasing requests for plumbing services;
  • – pipes in the water supply system are worn out;
  • – pipes are made of lead or polybutylene.


Pipe wear inspection

As the first step you need to look through the home inspection report. You had to get it when you bought your house.There you can find information about pipes you have. If you do not have this report, we recommend you book a plumber for a pipe inspection. In the table below you can find the pipes lifespan in dependence of their material.

Pipe type



Supply pipes


80-100 yrs

Supply pipes


70-80 yrs

Supply pipes

Galvanized steel

80-100 yrs

Drain lines

Cast iron

Polyvinyl chloride (PVC)

If you live in areas with hard water, which has high mineral content,  your pipes may worn-out sooner.  If your pipes are older than these guidelines, it doesn’t necessarily mean they need to be replaced. Well-maintained pipes may last longer, and poorly maintained ones may fail sooner.

Replacement of lead pipes

If your pipes are made of lead, you should replace them immediately. This is due to the fact that lead can get into the water and cause harm to health. Lead pipes were installed in the houses of the 1900s. Although their service life is more than 100 years, it is dangerous to use lead pipes in the house.

Replacement of polybutylene pipes

Polybutylene pipes are prone to frequent breakage and leakage. Replacing polybutylene pipes with stronger ones will save you a budget in the future. Polybutylene pipes were actively used in houses built between 1970-1990.

How long does it take to repipe a house?

The exact term for house repipe can be told by a plumber after evaluating the work. We can only describe approximate terms of works.

Usually, plumbing replacement in a small house takes from 2 to 4 days. If you live in a high-rise building with several bathrooms, then work can take a week or more.

Carrying out repairs does not mean that you will be without water all the time. You will be able to use sinks, showers and toilets. A house repipe shutdown occurs once when the plumber switches the plumbing to a new system.

How is the price of house repipe formed?

The house repipe cost depends on several factors, such as:

  • • house size;
  • • the complexity of the plumbing system;
  • • the material from which the pipes are made;
  • • scope of work;
  • • location and accessibility of pipes;
  • • pipe diameter.





House size. The cost of repiping a small one-story house is low, as it requires fewer materials. A large house repipe with several bathrooms will cost more, as the amount of materials and complexity of work increase. It is most expensive to replace pipes in multi-storey buildings.

The number of plumbing fixtures. The more connections to the plumbing system, the higher the price of house repipe. In other words, the more toilets, sinks, dishwashers, showers, washing machines in the house, the more expensive the procedure will be. So, for a house with one bathroom, the cost of replacing pipes is significantly less than for a house with three bathrooms.

Ease of access to pipes. The pipes behind the walls are easier to get to, so replacing them will be cheaper. On the contrary, the price increases if you need to climb into small confined spaces to access the pipes. 

Pipe diameter. The larger the pipe diameter, the more material is required. Accordingly, the price of such a pipe also increases.

Material of new pipes. Copper pipes are the most expensive. The cost of one foot of copper pipe ranges from $2 to $4. Pipes made of PEX or CPVC are cheaper: for one foot you will pay from $0.50 to $2.
