Firstly, you’ll need to select the right style of guttering for your house. There are a few different profiles, so make sure you match the style that’s currently on your house. If you’re not sure, just take a photo and bring it into Mitre 10 and they’ll sort you out with the right guttering.
FIND YOUR HIGH AND LOW POINTS
Establish your high point and your low point. The low point can be identified by existing downpipes or stormwater outlets.
Create a stringline, or chalk line between the high point and the low point. You’ll need a fall of 5mm per 10 metres so the water can drain properly.
ATTACH BRACKETS
Attach your first bracket to the high point on your facia.
Attach the dropper or expansion outlet to the low point – making sure you maintain your fall. If you need an end cap on your dropper, glue it on before installing using PVC Solvent Welding Cement.
Attach the rest of your brackets no more than 500mm apart, or 300mm apart in areas prone to high rain or snow.
CUT GUTTERING TO LENGTH
Now cut your guttering to length with a hacksaw. Guttering generally comes in 3m or 5m lengths, so if you need to join any pieces together just use a joiner to connect your two pieces, glued together with PVC Solvent Welding Cement. If your guttering is more than 10m long you’ll need to use an expansion joint, as guttering can expand and contract according to temperature.
Inside the expansion outlet you’ll need to line the guttering up with the marked temperature graduations. Slide the guttering in until it lines up with the temperature of the day.
If you need to, glue an end cap on the end of your guttering.
INSTALL GUTTERING
Install your guttering onto the brackets. Position the front of the guttering into the front of the bracket, then roll the spouting into the back of the bracket so it clicks securely into place.
CONNECT GUTTERING TO DOWNPIPES
There are a number of corner joints and downpipes available to use, so you’ll need to select the right parts for your particular situation.
For this job we’ll be connecting the guttering into an existing down pipe with a T-Joint, a 90° elbow joint, and a short length of pipe.
First, we placed the elbow joint onto the downpipe, positioned the T-Joint, and marked the section to be removed from the existing downpipe. The T-Joint is then glued into the missing section of the downpipe and the rest of the pieces are simply glued into place.
Screw the elbow joint, or downpipe into the expansion outlet/dropper.
