How to Deal With Leaking Downpipe Repair
If you have a leaking downpipe, it's important to remove the blockage as soon as you can and replace the damaged portion of pipe. Fortunately, all types of downpipes can be fixed with epoxy putty.
Clean the area first and take off any paint or rust, as well as any other debris. Cut the length of tape and wrap the joint in it, making sure the ends are in line.
Clean the area
After a leak, your first thing you should do is to remove any standing water and clean the area. Make use of a wet vacuum to remove any water that is still standing and clean up floors and walls that have been affected by the leak. This will also help prevent the growth of mould and mildew that can develop when an area that has been damaged by water is not properly dried.
Next, check for obstructions. Downpipes that are blocked can cause water to overflow, causing damage on your walls, guttering and foundations. Blockages can be caused by leaves, twigs and other debris in your downpipe and guttering. Ice can cause blockages as well when temperatures are colder.
In some cases the downpipe that's leaky may simply be blocked. It may be possible to remove it with a hosepipe and a wire or drain rod. However, it is recommended to regularly clean of your downpipe and guttering system to prevent the accumulation of dirt that could cause blockages.
If you are unable to remove the obstruction, it is likely that the section of downpipe below the leak has been damaged and may require replacement. This involves taking out the old downpipe and replacing it with a new one, using fittings and connectors.
Wear safety glasses and rubber gloves before you begin repairing the downpipe. Make use of a sturdy ladder when working at heights. Get someone else to assist you. Request someone to hold the hose at the bottom of the step ladder. Then switch on the water to full flow so that you can flush the downpipe. Guttering and Downpipe Services will let you work starting from the top downpipe and ensure that you don't miss any spots that require repair. If the clog continues to persist it is recommended that you remove the hose from the downpipe, and then use a plumber's snake to clear the obstruction.
Repair the joint
It's best to start any plumbing repair by locating the leak. The next step is to clean and dry the area. This will ensure that the sealant is adhered to the pipe in a proper manner. Before you begin, shut off the water supply at the valve closest to the pipe that is leaking.
It is important to stay clear of working on pipes that are wet, particularly in the event that the downpipe provides potable water.
Leaks in downpipes typically occur around the joins. The joins are typically exposed to harsh conditions, dirt and debris.
Once you've cleaned the area and made sure it's dry, cut a piece of repair tape about one centimetre larger than the length of the leak. Remove the backing paper from the tape and wrap it around the joint. Once the tape is secure then apply a large amount of gutter and roof sealant on both sides of the joint. Press with a firm pressure to create a solid seal.
If the leak is in a cast iron downpipe it could be that one of the fixing screws or nails has come loose. It is easily fixed by replacing the screw with a new galvanised screw. Alternatively, the downpipe could be loose due to an ineffective wall plug. If the downpipe is constructed of plastic the retaining clip might be loose and will need to be replaced.
PEX leaks are normally caused by the crimped connection which doesn't fully seal. A PEX Crimping Tool and a test gauge that is usually included with the tool can be used to fix this problem.
In addition, epoxy putty can be another good solution for leaky downpipes, since it can be made into a sausage shape to fit the leaking pipe joint. Apply the putty after blotting the pipe surface dry. Make sure to completely cover the crack or hole.
If the leaky downpipe is causing extensive damage your property, or is preventing rainwater from getting into your home, it's worth calling in a professional plumber for a quick and cost-effective solution.

Seal the joint
The joints around your downpipes can be a hot spot for leaks, especially if they're made of different materials (like metal and PVC). Keep these joints clean to avoid blockages which can prevent water from flowing freely, and can cause damage.
Regular cleaning will allow you to spot issues early and take preventative actions But sometimes, things go wrong and you need a quick fix to stop the leak. There are several products that you can use to make a temporary seal.
First clean the area around the leak to remove dirt and loose paint. Dry the area, then mark it with sandpaper to prepare it for the repair compound. Mix the ingredients for the putty and knead until the mixture is flexible. Press the putty firmly over the leak, overlapping the edges. Cover the area that has been repaired with a bandage and then wait several minutes or as directed by product instructions for the casting to harden.
Leaking downpipe joints can also be fixed with pipe repair clamps, which are available in various sizes to suit your gutter's width. These devices make use of the metal band with rubber gasket, which is secured with bolts to fix leaks temporarily at the pipe's end or along its length. Simply unscrew the bolts that secure the clamp and place it on the joint that is leaking and then tighten the bolts until they compress the gasket with rubber against the pipe.
A rubber pipe connector or repair sleeve is an alternative solution to fix leaky downpipe joints. These sleeves are flexible enough to wrap around a leaking joint, and they work well on polyvinyl chloride (PVC) pipes. You can also try self-fusing tape that forms the appearance of a compression seal, which can withstand water for up to three years if applied correctly.
PEX (pressurised ethylene) leaks in pipes are typically caused by a defective the crimp on a connection. These leaks can be more difficult to repair, but they are able to be remedied using specialized tools. You'll require a specialized crimp tool with a set of test gauges, also known as a "go/no-go" gauge that is the same dimensions of your PEX pipe. If the crimping is not working, you can re-crimp the pipe with the right tool.

You can purchase these from the internet or in your local hardware store. Certain are designed specifically to be used for drainpipes, and they come in a variety of sizes. A drain snake can be particularly helpful if you have a large amount of debris preventing water flow.
You can also make use of a wire or rod of metal to open the downpipe. Again, you should be cautious to stay clear of sharp objects and ensure you're standing on a sturdy ladder. Before you begin, switch off any electrical fittings, fixtures or cables close to the downpipe. It is also recommended to wear safety goggles and rubber gloves.
Another indication of a blocked downpipe is if there is a buildup of water at the gutters' bottom and along the wall. This can cause dampness and contribute to the growth of mould. You can stop this from happening by cleaning your gutters and downpipes and keeping overhanging tree branches kept tidy.
