Top Plumbing Issues To Watch Out For When Renovating

Struggling with plumbing problems while renovating? You don’t have to! In this article, we’ll reveal the most common plumbing issues and how to avoid them. Whether you’re starting from scratch or upgrading existing components, tackling plumbing problems is a must-know for any DIYer.

Leaks and Drips

Leaks and drips in a plumbing system are one of the top issues your plumber will watch out for when renovating. These types of issues can cause major damage to both the structure of your home as well as lead to high water bills. Pay close attention for any signs of leaks and drips, such as water pooling or staining on walls and ceilings, musty smells, or hearing running water when no taps are on. Any findings should be immediately reported to your plumber as soon as they are noticed.

When inspecting for leaks and drips, check all faucets, showers, toilets, water lines, drains, radiators and air conditioning units (HVACs) to make sure everything is in working order. You can also check toilet flanges for signs of excess moisture or wetness around the base of the toilet.

If you do notice any abnormalities or issues with any part of your plumbing system while renovating take care to:

  • Replace any outdated fixtures that may be contributing to the problem.
  • Make sure all parts are functioning properly before moving ahead with other renovations.

With frequent inspections and maintenance you’ll be able to keep your plumbing system functioning smoothly without costing too much in repairs or replacements down the line!

Clogged Pipes and Drainage Problems

Clogged pipes and drainage problems can be a common issue resulting from renovations. Issues can arise from the improper disposal of materials into the plumbing system. To prevent such issues, it is important to ensure that materials that should be disposed of in the regular garbage are not put down the sink or into any pipes. That includes items like paints, grouts, adhesives, food waste, and paper towels.

Also ensure any waste going into risk-prone plumbing i.e rags or sponges are disposed of correctly and do not clog your pipes; this is especially relevant if working on kitchens as grease build-up in pipes can become an issue quickly.

It is also a good idea to get an inspection of your drains and piping prior to renovation- make sure all your piping systems have been prepped correctly for intensive use after construction as this can greatly reduce potential for clogs or buildup within the plumbing network post-construction completion as debris such as dust from construction sites easily gets trapped in drainage systems during work activity; this could mean costly repairs down the line if left unchecked by professional plumbers post-renovation.

Outdated Plumbing Systems

The age of the existing plumbing system in your home is an important factor to consider when doing renovations. A lot of homes built before the 1950s had a simple gravity-based drainage system, and while they may function adequately with minimal maintenance, they do need to be replaced after a certain amount of time. Over time, things like corrosion and wear can take their toll on the plumbing, leading to problems such as leaks or noisiness from pipes.

If you have an older home that has still not been updated with a modern drainage system, it is essential for you to consider doing when renovating. Depending on the age of your home and what type of plumbing fixtures are currently installed, it may require more time and money for installation than some other issues. But installing new plumbing could increase the value of your property over time as well as provide a much safer environment for you and your family.

Updating outdated systems also means taking advantage of modern technologies like tankless water heaters or low-flow toilets that reduce water usage and conserve energy. You can also make sure that new piping materials are used since old galvanized drainage pipes can corrode over time and cause serious damage if left unattended too long. Arming yourself with knowledge about plumbing issues will help you make better decisions when renovating and protect you from future potential problems down the road.

Low Water Pressure

Low water pressure is a common issue when renovating a home and can originate from a variety of sources. One common cause is that the water supply has been shut off while work is being done, or bypassed to change out the pipes. Another cause may be that existing pipes are too narrow, not allowing enough water to flow through them, or that corrosion has accumulated in the pipes, blocking them. Additionally, if air leaks have developed in the lines due to corrosion, this can also lead to low water pressure.

If you are planning on changing out plumbing, consult an experienced plumber – they will be able to assess your current situation and advise whether you’ll need additional piping or larger pipes than your existing setup. They may also suggest solutions such as:

  • Replacing worn fixtures;
  • Widening old pipes;
  • Using different valving systems;
  • Using air-gap valves; and
  • Ensuring solid connections between pipe lengths, joints and holes in walls or floors.

Additionally, they may recommend flushing out system sediment and calcium deposits if any have built up in the pipes over time. Lastly, it’s important to make sure you have sufficient water pressure flowing from your municipal connections into your home, so work with your local municipal authority.

Faulty Fixtures and Toilets

Faulty fixtures and toilets are one of the most common plumbing issues that homeowners face when renovating. Issues with fixtures include broken pipes, faucets, showers, tubs and toilets. If you’ve noticed a decrease in water pressure or strange gurgling noises coming from your bathroom sink or shower, it could mean there’s a leak somewhere in your home. Additionally, if water is frequently pooling around the base of your toilet or dripping down the sides, this can indicate a faulty seal between the tank and bowl or a flapper valve problem.

To prevent further damage to your home – and costly repairs – it’s important to have these problems fixed as soon as possible. Generally speaking, either the fixture itself may need to be replaced or tighter connections may need to be sealed around pipes and fittings. In some cases such as with toilet-related issues, you may need to replace components such as the

  • flusher handle chain
  • flapper valve itself

Water Heater Issues

Water heaters are crucial to a functional household; they must be operational in order to provide hot water for showers, baths, and dishwashing. But when renovating, it is essential to recognize common water heater issues that may arise.

  • First, be aware that older units generally need to be replaced and properly disposed of. Consequently, it’s important to factor in the cost of a new unit before beginning the renovation process. Additionally, plumbing pipes and electric wiring need to be considered when installing or replacing a water heater; you’ll likely need the services of both an electrician and a plumber to have everything properly installed.
  • Beyond installation costs, you should think about the type of unit best suited for your needs. Tankless water heaters – which are becoming increasingly popular – deliver hot water more quickly than conventional storage-tank heaters while also taking up less space in your home. On the other hand, storage tank systems offer more economical costs upfront but require frequent maintenance such as flushing the tank annually and checking temperature levels bi-annually for peak efficiency and longevity.
  • Finally, regularly check for signs of leaking; wet spots or rust on walls or flooring often indicate maintenance problems related to your hot water heater system. If you’ve noticed these signs during your renovations or after completing them, contact a professional plumber immediately for assistance with repairs or replacement before additional damage is caused by extensive leaking from the unit itself!

Poor Ventilation and Drainage

One of the major plumbing issues to watch out for when renovating your home is poor ventilation and drainage. Ventilation and drainage are critical for ensuring the longevity of your plumbing fixtures and preventing the buildup of unpleasant odors in the home. Poor ventilation can lead to humidity and mold problems, which can lead to long-term damage to your home’s structure.

To ensure that adequate ventilation and drainage are installed, hire a professional plumber who can evaluate your plumbing system before beginning your renovation project. Poor ventilation can also cause blockages in drains as well as pipes, requiring professional assistance to clear them out. If you are dealing with older pipes that need replacing, make sure that you work with a professional who specializes in this type of work.

Corroded Piping

When undertaking any type of renovation project, it is important to check existing pipes and plumbing. Checking for corrosion is key as corrosion of copper, galvanized, or polybutylene piping can cause serious structural damage to your home. Corroded or leaking pipes will need to be replaced, and any connecting parts must be inspected for signs of wear. Additionally, rusty water may indicate a corroded pipe problem and should also be looked at.

If your home has older piping that hasn’t been maintained properly, it may be time to consider replacing them with new plastic materials such as PVC or PEX tubing which are more durable and less prone to corroding. Your local plumber can help you identify the best course of action for your home.

Inadequate Water Supply

Inadequate water supply is one of the most common plumbing issues faced by homeowners during a renovation. This essentially means that the amount of water coming into the house is not enough to meet your needs. This can lead to low water pressure in your fixtures, as well as restricted use when multiple fixtures are being used at the same time.

It is important to get an accurate assessment of your current water supply before starting any renovations in order to avoid this problem. Additionally, make sure all pipe connections at the source and throughout the home are secure and free from leaks. Even small holes can cause major plumbing problems, so addressing them before beginning a renovation can save you time, money and energy in the long run.

Incorrect Installation of Plumbing Systems

Improper installation or connection of new or existing plumbing systems can cause a range of plumbing problems that are both costly and time-consuming to repair. It is essential to ensure that any plumbing system is connected correctly and correctly installed before commencing renovations.

Common causes of plumbing issues include, but are not limited to:

  • Incorrect installation of pipes and fixtures.
  • Failure to seal joints securely with correct materials and techniques.
  • Misconnection of pipes and fittings.
  • Incorrect sizing or positioning of drainage lines.
  • Failure to carry out required pressure tests during installation process.
  • Improper connection of water supply lines.

It is important to consult with an experienced plumber in order to identify any potential issues prior to undertaking renovations as well as receiving advice on the best ways to proceed when beginning a renovation project. If any areas require further expertise then additional support should be sourced from a suitably qualified professional who has experience working on similar projects.


At the end of any renovation, one of the most important tasks you must complete is a plumbing inspection. You should consult with an expert to assess the quality of your updated plumbing to ensure that all connections are secure and no water damage has occurred. This will help protect your home and your family from potential problems such as leakage, leaks that can lead to mold growth and structural corrosion.

Doing this may also save you time, money and stress in the long run if you have professional assistance coming in routinely to check up on your newly renovated pipes and fixtures. Remember, even small issues can lead to larger problems down the line if not addressed promptly. Neglecting regular maintenance and inspections could turn out to be costly in the future, so consider hiring a licensed plumber for peace of mind.
