How to Deal With Leaking Downpipe Repair

If you are experiencing a leaky downpipe, it is important to clear the obstruction as soon as you can and replace the damaged section of pipe. Fortunately, the majority of downpipes can be fixed with epoxy putty.


First clean the area of leakage and remove any loose paint or rust. Cut an appropriate length of tape and wrap the joint with it, ensuring that the ends meet.

Clean the area

After a leak, the first step is to eliminate any standing water and then clean the area. Make use of a vacuum cleaner to eliminate any standing water and then clean the floors and walls affected by the leak. This can also help prevent the growth of mildew and mould which can happen if the affected area is not properly dried.

The next step is to check for blockages. Blocked downpipes can cause water to overflow which causes damage to your walls, guttering, and foundations. Leaves, twigs and other debris in your downpipes or guttering can blockage your downpipe by preventing water from flowing freely, and ice at lower temperatures can also impede the flow of water.

In some instances, the downpipe that's leaky may be blocked. you could try this out may be able remove it with a hosepipe and a wire or drain rod. It is important to wash your guttering and downpipe on a regular basis to avoid the accumulation of dirt that can cause blockages.

If you are unable to remove the obstruction, the section of the downpipe beneath the leak could be damaged and needs to be replaced. This requires removing the old pipe and replacing it with a new one with connectors and fittings.

Wear safety glasses and rubber gloves prior to you begin to repair the downpipe. If you are working at high altitude, you must use a solid ladder and ask someone else to support you. Ask someone to hold the hose at the bottom of the step ladder and switch on the water to full flow so that you can clean the downpipe. This will allow you to work from the top of the downpipe, and will help ensure that you do not miss any areas that need repairing. If the blockage persists, it is best to take the hose off the downpipe, and then use a plumber's snake to clear the obstruction.

Repair the joint

Like any plumbing repair, it's always best to start by finding the source of the leak. Then, clean and dry the area. This will ensure that the sealant is adhered properly. Shut off the water source near the leaky section of pipe before you begin.

It is important to stay clear of working on pipes that are wet, particularly when the downpipe is supplying potable water.

Leaks in downpipes are often caused by the joints. This is because the joins are exposed to harsh weather and the accumulation of dirt and debris.

After you've dried and cleaned the area, cut a length of tape that is approximately one centimetre larger than the length of the leak. Remove the backing paper from the tape and wrap it around the joint. When the tape is in place, apply an ample amount of gutter and roof sealant on both sides of the joint. Press with a firm pressure to ensure a good seal.

If the leak is coming from a cast-iron downpipe, one of the fixing screws or nails could have slipped out. This can be fixed by replacing the screw with a new galvanised screw. The downpipe could also be loose because of an ineffective wall connector. If the downpipe is constructed of plastic, the retaining clip may be loose and require to be replaced.

PEX leaks are typically caused by an uncrimped connection that does not fully seal. This can be easily corrected by using an PEX Crimp Tool and a test gauge, which are usually included with the crimp tool.

In addition, epoxy putty can be another good solution for the downpipe that is leaking, as it can be moulded into a sausage-like form to fit the pipe joint. Apply the putty after blotting the pipe surface dry. Make sure to completely cover the crack or hole.

It is advisable to contact a professional plumber if the leaky downpipe is causing significant property damage or hindering rainwater from entering your home. This is a low-cost and hassle-free solution. It is also important to maintain your guttering regularly to avoid problems in the future, such as downpipe leaking.

Seal the joint

Leaks can occur at the joints that connect your downpipe, particularly if it's made of different materials. Keep these joints free of blockages that could block water flow freely, and cause damage.

Regular cleaning will aid in identifying problems early and take preventative actions, but sometimes things go wrong and it is necessary to make a quick fix to stop the leak. You can create an interim seal by using a variety of products.

Clean the area around the leak first to remove any paint or dirt that has escaped. Dry the area and score it using sandpaper. This will prepare it for the repair compound. Mix the components of the putty and then knead it until it is malleable enough to mould to the damaged area. Cover the edges with putty and press it firmly on the leak. Cover the repaired area and then wait for a few minutes, or as directed in the instructions for the product to ensure that the cast has a hardening.

Leaking downpipe joints can be fixed using pipe repair clamps, which are available in a variety of sizes to suit your gutter's width. These devices make use of the metal band with a rubber gasket secured with bolts to temporarily fix leaks at the pipe's end or along its length. Remove the bolts that are holding the clamp, and move it over the leaky joint. Then tighten the bolts so that the gasket is pressurized against the pipe.

Repair sleeves are a different option to fix leaky downpipe joints. These sleeves are flexible enough to wrap around a leaky joint and are able to work on polyvinyl chloride (PVC) pipes. You may also try self-fusing pipe tape that creates a compression seal that resists water for up to three years if it is applied correctly.

A faulty crimp is usually the reason for leaks in PEX (pressurised Ethylene) pipes. These leaks are more tricky to repair, but they can be repaired with the help of special tools. You'll need a specialised tool that has the test gauges (also known as "go/no go" gauges) that match the size of your PEX pipes. If the crimping isn't working, you'll need to re-crimp the pipe with the right tool.

Clear the blockage

Blocked downpipes are common causes of water damage to homes. They can cause flooding, damp walls, and roof damage. It is crucial to clear a blockage quickly and efficiently to avoid further damage.

If you have a blocked downpipe, the initial thing to do is turn off the water supply. Get rid of any debris in the downpipe or around it that could be blocking the pipe. Wear rubber gloves and dust masks to protect yourself from any corrosive substances.

A garden hose can be used to spray water down the drainpipe to clear any obstructions. If this doesn't work then you can try a plumber's snake. These can be purchased from the internet or at a local hardware store. Some are specifically designed for downpipes and come in a variety of sizes. Drain snakes can be particularly helpful in the event that you have a substantial amount of debris that is preventing the flow of water.

You can also use a wire or a metal rod to unblock the downpipe. Again, you should be cautious to stay clear of sharp objects and ensure you are on a stable ladder. Before beginning, turn off any electrical fixtures, fittings or cables close to the downpipe. Wearing rubber gloves, safety goggles and safety glasses are recommended.

A accumulation of water along the wall and at the bottom of gutters is another indication of a blocked downpipe. This can cause dampness and lead to mould growth. You can prevent this by cleaning your downpipes and gutters and keeping tree branches that hang overhanging cut.

Downpipes that are blocked can be difficult to clean and it's important to take care of them as soon as possible to prevent further destruction to your home. If you don't have the time or inclination to clean your downpipe by yourself it might be a good idea to call a professional.
