7 signs that indicate you have a plumbing problem


Nothing can be more frustrating and costly than a full-blown plumbing problem. A clogged drain and a dripping or leaking tap are problems that are easy to fix. Burst pipes, blocked or broken toilets, and colored, odorous water coming out of your taps are more serious issues that require expensive and lengthy repair services.

Learning to spot the early warning signs of the usual plumbing problems can save you thousands of dollars. It will also prevent the need for expensive, inconvenient, and overlong repairs.

Plumbing Problem Signs to Watch Out For

The team at Blue Diamond Plumbing shares a list of the usual signs that indicate the beginning or presence of a plumbing problem that needs to addressed quickly and properly:

1. High monthly water bills

One or two high water bills a year, on separate occasions, are bearable. However, if you already had a huge water bill last month and the amount is more or less the same now and you can’t think of any changes in your average water usage, chances are, you may have a hidden leak.

Since you can’t see the leak or leaks, you will have to call a professional trustworthy plumber so that he can pinpoint the exact location of the dripping pipe.

2. Mold and mildew inside cabinets and on walls outside the bathroom

Mold and mildew thrive in damp or humid areas. It is true that some homes experience high levels of humidity to allow mold and mildew to appear even in the absence of leaking pipes.

However, these harmful fungi typically spring up when leaking or broken pipes provide a higher than normal level of water in the walls. As such, their presence means you have one or more leaky or damaged pipes hidden somewhere in your home that needs to be repaired immediately.

3. Leaking pipes

If you see water dripping from a pipe whenever you open the cabinet beneath your kitchen or bathroom sink, there’s a high chance that you already have a plumbing problem which will get exponentially worse if it is not fixed immediately.

A leaking pipe usually means that it is already rusting and has holes where the water can seep through. To avoid this plumbing problem from getting worse, the rotted section of the pipe or possibly the whole pipe must be replaced.

4. Sudden drops in water pressure

If you experience a sudden decrease in the water pressure, this is usually a sign of dangerous clogged or leaking pipes.

These clogs can lead to pipe ruptures which, in turn, can damage your home’s foundation, walls and roof. These leaky and blocked pipes can also cause the formation of mold and mildew.

5. Cloudy, discolored, or rusty water coming out of the faucet

Contaminants and other impurities can cause discoloration or clouding of water. usually, the water will have an unpleasant or rusty smell as well.

Most contaminants come from problems in your water supply. However, old or leaking pipes and water heaters can also cause water contamination and discoloration.

6. Recurring toilet backups or clogs

Nothing can be more annoying than being unable to flush the toilet; this is not only gross, but it can also become a huge sanitary issue.

If this is a problem you consistently have in your bathroom, call a professional plumber. You may have an issue somewhere in the toilet tank or you may need to have your septic tank emptied.

7. Slow draining sink and bathtub

If it seems like you need ages to empty your sink and bathtub or the water isn’t draining at all, you most likely have a blocked pipe.

Although you can use certain products and tools to fix this problem, it is still best to have a professional plumber clear the clog. Aside from getting rid of the blockage, the plumber can check to make sure it isn’t a part of a bigger issue.

Once you discover a plumbing issue, whether it seems easy to fix or not, it is always best to call a professional plumber immediately. You will save more money and avoid a lot of inconveniences if you let the pros deal with the problem from the start.

  • A lot of people will try to fix the moisture problems by just treating the symtoms (cleaning mold off the walls) rather than finding the source of the problem (leaking pipes and gutters, stormwater not draining away and collecting under the house). This can lead to more expensive issues if not fixed properly early on.

  • I just had a water pressure issue in my home. Every time something was using water, there was only enough pressure for that. Once something else asked for water, there goes the pressure. Turned out that it was our pressure reducing valve.
    Also turns out my dad is a master plumber so that was cheap. Thank goodness.

  • hi from West Australia. I just wanted to say thanks for taking
    the time to share this information.The plumbing principles
    you have written about are similar to where I come from.
    Thanks for sharing your knowledge.

  • Hello there, great post. Thanks for sharing the tips.

    It’s everyone’s nightmare…I for one I hate to find that I have some plumbing issues at home. Just to thing of the amount of work and stress involved in the process of DIY plumbing or getting a pro to fix it … sometimes not being able to have a shower for days and so many other things that comes with plumbing problems.

    I’ve learned to maintain the plumbing around the instead of getting to wait until something break down … so nowadays I do regular checks and maintenance to my home plumbing.

    I usually do some basic plumbing like changing a sink or a faucet but if I’m not comfortable … I’ll just have to call a pro to do it!

    Thanks for sharing this useful tips!

  • Adding insulation to your home is a great way to increase the comfort of your living environment. Adding home insulation to an existing home will regulate the temperature, making your living environment more enjoyable, especially in places of extreme weather.

  • It was really nice how you discussed that contaminants, as well as old, rusty pipes, can cause discoloration of water and so we need to call a plumber once we see it. I think that it’s very timely for us to read this because that’s exactly the case in our household. My sister mentioned that the water coming from the kitchen sink was yellowish in color and that she was afraid to wash the dishes and the food using it. I checked earlier and realized that it has gotten worse because the water was reddish now. I think we really do need to call a professional. Thank you for sharing.

  • I sure appreciate how you said that the sudden decrease in the water pressure should be taken seriously as it serves as a sign that there’s heavy clogging in the pipes. If I didn’t read this article I would have taken my brother’s complaints for granted. He talked to me last night saying that there’s a problem with the faucet and that water isn’t coming out as fast as it usually does. I thought it was normal and that water pressure will return the next day, but it didn’t happen. I may need to get in touch with a plumber to get this checked. Thank you for sharing.

    If you have a toilet that’s constantly clogged, you may be flushing too much down your toilet. Only flush down toilet paper and you’ll have a lot less clogging. This may seem like a small change, but it will make big difference. Remember, you have a garbage bin in your bathroom for a reason.
