How To Install Gutters
Videojug demonstrates different techniques, details and specifications of gutter installation, ways of sloping, accurate measurements and tools for work. Follow these guidelines to get clear installation instructions in an aesthetic manner, that help your gutter pipe last longer without leakage and prevent water accumulating.
Have a look at plastic guttering. The installation of guttering is very straight forward. The fittings are designed to be screwed directly to the facia board or soffit, so all of the fittings will come with pre-drilled holes, ready for that attachment.
The way that the plastic guttering that goes together is a clip system - two plastic clips either side, there is a rubber washer, sits inside, and provides a waterproof seal. The way that you actually attach the two together is quite important, because you don't want to get excessive strain on the clips, so they won't snap. So, the best technique is to introduce the gutter into the fitting so that they engage fully on one side and then bring it around into the other clip and that will then snap on.
So, nice and easy to use, and that will give you a waterproof joint. Gutter isn't designed to slope particularly. It's fitted almost level.
The way that the gutter operates is by this fitting called running outlet being slightly lower than the base of the gutter, this allows the water to run out. What we don't want is to add momentum to the rain water. If we have two sleeper pieces of gutter, all that will happen is that the water will fly off the end, whatever stop we have on there, it will fly over the end.
So, the measurement we will go for is one millimetre drop for every 600 millimetres of length. What that effectively means is that we will take the length of the gutter that we are going to run, divide it into 600 millimetres section and that will tell us how many millimetres we need to drop from the starting point, to the stop end down into the running outlet. Too shallow and you are going to get dirt building up and with the rainwater, you will end up with grass and as if you are using a nice bird bath.
And too steep, it will run off the end. So, once that fall is set and marked on the facia board, we can fit the first fitting. You always work from the lowest point, so we will fit the running outlet first.
What we'll then do is position the facia bracket, and they want to be less than one meter, no more than one meter apart. We will normally go about 750 millimetres between them but the measurement is no more than one meter apart. Again, very straight forward to fit, you can use an electric screw driver and simply drive the screws home.
You need to be careful not to put too much torque on there because it is already plastic and you can't snap it. Let's pop another one on the other side. Okay, we are going to use the same technique to fit the gutter.
What we are going to do is introduce the package and allow it to come around and give that screw and a little bit of a tightening. We are going to allow the package to engage first. As it runs in to the fitting, you now allow the clips to take over and that's nice and secure.
Inside the fitting there is a mark and that mark will tell you how far you can actually engage the gutter. Gutter expands and contracts quite a lot, so the consequent fittings are designed for it to be able to move. It's important that we haven't fixed it.
If we have fixed it too securely, then what will happen is it will pull itself out of the fitting or it will distort. So, the gutter has to have that little movement in it, it has to be allowed to expand and contract. This is an internal stop end.
We have put a stop end at the other end, so we have a stop end that is external at that end, internal this end, and again, engage it into the fitting, clip it home and that now holds it securely. The down part that we use is a 50 millimetre plastic pipe. That engages onto the bottom of the running outlet.
It's held in a down-part clip. The down-part clip is no more than two metres apart, so as we go down to the side of the building, we want to be looking at roughly something in a ratio of one and a half meters apart or something like that, but certainly no more than two meters apart. Secure the other side, I just start
