Is it necessary to build a wall if the water pipes in an old house are leaking? A complete guide to the cost of reconfiguring open and concealed water supply pipes, stainless steel crimped pipes and decoration modifications

When water pipes in old houses seep slowly in the walls, the dilemma you face

In old apartments in Taipei and New Taipei that are more than 30 years old, the most common water supply pipes are early "galvanized iron pipes (white iron pipes, but the joints are easy to rust)" or "uncoated PVC plastic pipes". After decades of chloride ion corrosion in tap water and earthquake stress, there are many cases of hot water pipe joints becoming rusty and punctured, and cold water pipes bursting and leaking. When it is discovered that the walls of a house have become damp and the water meter is still turning slowly even when no one is using water, the most troublesome question for homeowners is often: Do they have to knock out the tiles in the whole house and carry out extensive construction work to install new hidden pipes? Or can I choose to use "open management"?

Exposed pipes vs concealed pipes: Comprehensive evaluation of construction methods, costs and durability

Modern exposed pipe standard material: SUS304 Stainless steel double crimped covered pipe

Many people’s impression of exposed pipes is still the traditional ugly silver iron pipe or yellow PVC pipe, but the exposed pipes used in modern high-quality hydropower projects have long been fully upgraded to "SUS304" "Stainless steel double pressure pipe" with "insulation and anti-condensation coating":

• Food grade hygiene and safety: The inner wall of the stainless steel pipe is smooth and non-toxic, and will not release plasticizers, completely solving the health hazards of yellow and turbid rusty water flowing out of old iron pipes.
• Double Press method: Using imported hydraulic crimping pliers, paired with EPDM rubber sealing rings that are resistant to high temperature and high pressure, exerting a uniform and strong bite force on both ends of the pipe fitting, the shock-proof and leak-proof performance is far better than traditional thread locking.
• Foam insulation coating: The outside of the hot water pipe is covered with a bright and heat-resistant insulation jacket (usually red or blue coating), which can effectively reduce the heat loss during the transmission of hot water and prevent high-temperature burns on the pipe wall and condensation on the outer wall of the cold water pipe.

How to modify the exposed tube? Three design techniques to integrate into home style

If you are worried that exposed pipes will damage the interior decoration texture, you can use the following low-cost but highly aesthetic methods to modify them:

1. Seamless ceiling/skirting board wiring:Pipelines should be arranged horizontally and vertically along the corners of the wall, under the ceiling beams, or on the top of the skirting boards, and neatly fixed with pipe buckles of the same color. If the wall is lily white, you can use white coated pipes or spray latex paint of the same color to make the pipes invisible and blend into the background.
2. Partial wood cladding and false beam design: In the corridor or living room aisle, use simple partial wood false beams, curtain boxes or shaped leaf boards to hide the water pipes, and reserve magnetic inspection openings at the corners to take into account both aesthetics and maintenance convenience.
3. Rugged and neat light industrial style (Loft Style): In modern industrial style or retro Nordic style spaces, stainless steel metal pipes themselves are very distinctive design elements. As long as the plumber and electricity master lays out the horizontal and vertical positions extremely accurately and the spacing between pipes and clamps is symmetrical, the exposed metal pipes can create a pure and neat space craftsmanship aesthetic.

In which case is it strongly recommended to choose open pipe?

If your house falls into the following three scenarios, installing stainless steel open pipes is definitely the most cost-effective and wisest decision: First, it is expected to take 5 to 10 Old apartments that are undergoing renovation or dilapidated reconstruction plans within the year are not worth spending hundreds of thousands of dollars on the whole room and wall. Secondly, if the house is currently being rented or the owner cannot move, the leakage problem needs to be solved in the shortest construction period (1 to 2 days). Thirdly, it is difficult to catch leaks between shared pipes in old buildings. An independent and dedicated open pipe can be directly connected from the water meter on the top floor to the home, completely getting rid of neighborhood leakage disputes.
