Is There a Home Remedy for a Blocked Drain Pipe Outside the Home?
You might prefer to avoid chemical drain cleaners if you can, and there is no harm in initially using a homemade drain cleaner as a drain unblocker.
A simple mixture of boiling water, baking soda and vinegar is a good starting point when working with external drain blockages. This will bubble up but there is a pretty good chance you will need a few goes to unblock a drain and rid yourself of a clog or debris. You might even need to let it work overnight to fully clear or unblock a drain outside your house.
The Homemade Remedy is Amongst the Best Drain Unblocker Options
Of course, with severe blockages, you’ll likely need something more severe, and this is where other tools or chemical drain cleaners will be the best drain unblockers for you.
Can You Unclog an Outside Drain Manually With Tools?
Yes, it is often possible to unclog an outside drain manually, and if you find homemade or commercial drain unblockers don’t work, this is your next step to removing blockages from outside drains.
Items you should have handy when unclogging a drain include rubber gloves, goggles, a face mask, drain rods (or an auger or drain snake), buckets, bin bags and a hose. Remove the drain cover, taking care with heavy outdoor drains, and place any removed exterior drains carefully in a place you can find them.
Don’t Get Your Hands Dirty
You should try to remove as much debris and water sitting from drains as you can, preferably manually. This is why having rubber gloves is vital because the more debris and blockage you can remove manually by reaching into the drain and grabbing leaves, roots and other waste, the easier it is to unblock a drain.
Drain Rods Are an Integral Tool in Unblocking a Drain
If this step doesn’t clear the pipes, an unblocking tool is your best bet with an outdoor drain and tough blockages. Drain rods are the most common tools to unblock a drain. You need to insert the rod until you start to feel resistance from blockages, and then twist the drain rod. You might need to use force to unblock drains, so make sure you or someone helping you has the strength and know how to use this device to its fullest.
All being well, this motion will smash through the blockage, creating a clear path. If you don’t reach the blockage, you’ll need to add more rods until you do.
Once the blockage is removed, remove the rods and clear up the drain and external area. If you have high-pressure water jets, hose the area down for complete peace of mind.
Can You Hire Professional Drain Unblockers?
Given this is a messy job that requires time, effort and specialist equipment, it is easy to see why many people prefer to hire a specialist to resolve any external drainage issues they have.
As of October 2023, Checkatrade cites the following costs associated with hiring a professional to unblock your outside drain:
