How to Deal With Leaking Downpipe Repair
If you have a leaking downpipe, it is important to remove the blockage as soon as you can and replace the damaged portion of pipe. Fortunately, all types of downpipes can be repaired with epoxy putty.
First clean the leaky area and clean off any paint or rust. Cut the length of tape and wrap the joint in it, ensuring that the ends overlap.
Clean the area
Following a leak, the first thing you should do is to get rid of any standing water and clean the area. Use a wet vacuum to remove any standing water and clean the walls and floors affected by the leak. This will also help to prevent the growth of mould and mildew that can develop when an area that has been damaged by water is not dried properly.
Then, look for obstructions. Blockages in the downpipes cause water to overflow, causing damage on your walls, guttering, and foundations. Blockages can be caused by twigs, leaves, and debris in your guttering and downpipe. Ice can also cause blockages in colder temperatures.
In certain instances, the downpipe that's leaky may simply be blocked. It is possible to remove it with the help of a hosepipe, wire or drain rod. It is essential to clean your guttering and downpipe regularly to prevent the accumulation of dirt which can 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 will require taking the old pipe out and replacing it with a brand new one, using connectors and fittings.
Before you start to repair the downpipe, ensure that you are safe by wearing rubber gloves and safety glasses. If you're working at high altitude, you must use a solid ladder and have someone assist you. Have someone hold the hose at the bottom of the ladder and switch the water on full flow so that you can flush out the downpipe. This will allow you to work from the top of the downpipe and make sure you don't miss any areas that require repair. If the clog continues to persist it is recommended to take the hose off the downpipe, and then use the plumber's snake to remove the obstruction.
Repair the joint
As with all plumbing repairs it is always recommended to start by locating the source of the leak. The next step is to clean the area and make sure it's dry. This will ensure the sealant is properly adhered to. Before beginning, shut off the water supply to the valve that is closest to the pipe section that is leaky.
This is particularly crucial in the event that the downpipe is supplying potable water. You don't want to be working with pipes that are leaking!
Leaks in downpipes are often caused by the joints. The joins are typically exposed to harsh weather conditions, dirt and debris.
Once you've cleaned and dried the area, cut a piece of tape that is approximately one centimetre larger than the width of the leak. Remove the paper backing from the tape and wrap it around the joint. Once the tape is in position, apply large amounts of gutter and roof sealing compound to both sides of the joint. Press with a firm pressure to ensure a good seal.
If the leak is in a cast iron downpipe, it could be due to one of the fixing screws or nails have come loose. It is easily fixed by replacing the screw with a new galvanised screw. The downpipe could be loosened due to a faulty wall connector. If the downpipe that is leaking is plastic, it could mean that the retaining clip is loose and requires to be replaced.
PEX leaks could be caused by a crimped connector that does not seal completely. A PEX Crimping tool as well as an instrument for testing that is typically included with the tool are able to fix this problem.
Alternatively, epoxy putty is an alternative to a leaking downpipe, as it can be molded into a sausage shape to fit the pipe joint. Apply the putty after blotting the pipe surface dry. Make sure to cover the entire crack or hole.
It's worth contacting a professional plumber if the leaky drain is causing severe property damage or preventing rainwater to enter your home. This is a low-cost and hassle-free solution. It is recommended that you conduct regular maintenance on your gutters to avoid problems like leaks from your downpipe in the future.
Seal the joint
The joins around your downpipes can be a hotspot for leaks, especially in the case of pipes made of different materials (like metal and PVC). Cleaning these joints can help avoid blockages that prevent water from flowing freely and could lead to damage.
Regular cleaning will help you spot problems early and take preventative measures 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 few different products.
First, clean the area around the leak to eliminate dirt and loose paint. Dry the area, then score it with sandpaper to prepare it for the repair compound. Mix the ingredients for the putty and then knead until the mix is pliable. Overlap the edges of the putty and press it firmly on the leak. Cover the repaired area and let it sit for a few minutes, or as directed in the product instructions to ensure that the cast has a hardening.
Pipe repair clamps are used to fix leaking downpipe joints. They are available in different sizes based on gutter's width. These devices use the gasket of a metal with a rubber band to repair leaks along the length or end of a pipe. Unscrew the bolts holding the clamp, then place it on a leaky joint. Then tighten the bolts so that the gasket is pressurized against the pipe.
A rubber pipe connector or repair sleeve is an alternative option to fix leaky downpipe joints. These sleeves are flexible and can be wrapped around a leaky joint. They work well with polyvinylchloride (PVC). You may also try self-fusing pipe tape that forms a compression seal that resists water for up to three years if applied properly.
A faulty crimp is usually the cause of leaks in PEX (pressurised Ethylene) pipes. The leaks can be fixed with the help of specialized tools. You'll need a specialised Crimp tool and the test gauges, known as a "go/no-go" gauge that's size is a reflection of the size of your PEX pipe. If the crimp has failed then simply re-crimp the pipe using the proper tool.
Clear the blockage
The water damage in homes is usually caused by blocked downpipes. They can cause flooding, damp walls, and roof damage. To prevent further damage, it is important to get rid of a blockage as quickly as you can.
Shut off the water supply in the event of a blocked downpipe. Then, take out any debris blocking the pipe from the gutters and the surrounding area. You should also wear rubber gloves and a dust mask in order to shield yourself from any dangerous substances.
A garden hose used to spray water over the downpipe can help dislodge any blockages. If this doesn't work, try using a plumbing snake. You can buy these online or at your local hardware store. Some are specially designed for downpipes and come in a variety of sizes. Drain snakes are particularly beneficial if there is a lot of debris blocking water flow.
You can also deblock the downpipe by using a rod or wire. Again, you should be careful to avoid any sharp objects and ensure that you are on a level ladder. If the downpipe is close to electrical fixtures, fittings or cables, ensure they are shut off prior to beginning work. Wearing rubber gloves, safety goggles and safety glasses are recommended.
Another sign of an obstruction to the downpipe is when there is a build-up of water around the gutters' bottom and along the wall. This can lead to dampness and mould growth. It is possible to prevent this by regularly cleaning your gutters and downpipes and keeping branches that hang overhanging trimmed.
It isn't easy to tackle a blocked downpipe. It is crucial to act immediately to avoid further damage to your house. However, if you do not have the time or desire to cleanse your downpipe by yourself It might be a good idea to call an expert. Downpipe Services will have the tools and expertise needed to handle more complex obstructions, and will be able to offer a solution that is effective. They can also offer advice on how to maintain the downpipes to minimize the possibility of blockages occurring in the future.
