10 Not-So-Obvious Plumbing Issues Which Costs Thousands For New Homeowners

Are you looking to buy a new property? A lot of new homeowners have their dream properties turn to nightmares because they weren’t able to see the plumbing issues prior to the purchase. These issues were also not seen by building inspectors. Many buyers did not inspect the plumbing since this is not their area of expertise, and several building inspectors do not have this expertise too.

Be wary of these 10 not-so-obvious plumbing issues.


An in-depth inspection of a roof can save you about $10,000 to $50,000 in costs to get it replaced.

  1. Check the roof’s condition: The inspector should go up to check a roof out. A red flag should be raised when there is rust. There are even instances when seedlings grow out from roofs.
  1. Newly painted or newly renovated roof: This might just be a cover up.
  1. Hidden access points: When people have things to hide in their roofs or sub-floor areas, they usually conceal their access points. You must be wary when an inspector tells you about these access points being hard to find or hidden.


Many of the hidden problems are about water leaking in inappropriate places, where these can add to a maintenance budget for a property.

  1. Substandard tiling job: When a place has gone through poor tiling or re-tiling, think of how the waterproofing may be like. Cheap waterproofing can cost a lot since you will pay for leak detection, as well as band-aid repairs or even an entire bathroom renovation.
  1. Kitchen or bathroom renovations: When these renovations are done by an owner builder or unknown builder, you should be doubtful of the quality.
  1. Secure a copy of the property’s drainage diagram: Make sure this is the latest one too. When there is no diagram, buy one since this is worth so much. Diagrams get updated for changes done to drainage.


A big storm water or sewer issues potentially cost $20,000 or more.

  1. Check the hot water unit’s age: This can be found in the badge. They have an 8 to 10-year life when poorly maintained or a 15 to 20-year life when regularly serviced. If this unit is 8 years old and more, you should factor the replacement costs, which start from $1000 and usually averages $2000 to $3000.
  1. Galvanized pipes: Check outside walls for any exposed gas or water pipe. When it is copper, check the surface. Thick, rough or pitted ones can be galvanized and costs should be factored in.
  1. Sewer pipes. Check for clay pipes in the down pipe’s or garden taps’ base. Factor in replacement costs for the drainage system since these clay sewers are going to break, just a matter of when.
  1. Cuts in the concrete. If there are cuts, it means that it was investigated for drainage issues in the past.


You should make sure that the building inspectors know about these red flags. Otherwise, it is best to ask help from professionals like Technical Heating Services, who are experts in plumbing and heating services.
