So if the water level is above the pump, all you need to do is make sure the rain water can run through to the inlet of the pump. So you just snug those up, then you’ll probably just need to snug up the big loose nut connections to get that o-ring nice and tight, right? And then she’s all good to go, you can turn the water on, so it gets to the pump.Īnd the only thing we need to do now is just to prime it. Remember there’s a tag on there that says “no tools, just tighten them up by hand,” so that’s referring to the adjustable nuts. See the adjustable connections are just unreal. The outlet goes off to the house and there’s a filter underneath there, so that’s all connected. So we’ve got the rain water connected to the inlet. ![]() See how we can adjust the angles, get it all right, and it’s very easy to adjust and to lock it in place, makes it super easy for us. Now this is where the articulation comes in really handy on the inlet and outlets. Put it on like that, this nut has to go as easy as possible on there, tighten it up to jam that o-ring, and then it’s going to be all good and sealed, and it won’t drip. So never ever, if you’re using loose nut connections, never ever use thread seal. All that’s doing is making this nut harder to screw on and you want that as easy as possible, because you want to compress that o-ring. Now I’ve seen a lot of times where guys put thread seal on this thread. The nut here, that is what screws onto the thread, and that’s what jams that o-ring nice and tight. With these loose nut connections, it’s very important that you understand, so the o-ring is what seals the two parts together. So all I need to do now is to run the pipe around here and into the inlet, into this loose nut connection. You see the feed from the rainwater tank. So you can see the isolation valve is now installed. We’re going to use a crimper, you can use PVC fittings if you like, then you don’t need that, but you can hire these things as well. In the video, we show you the tools you’ll need: Then when you put the thread seal on and you go around like this, it bites in, stays where it is, and it won’t leak. ![]() The only way to get rid of that is grab your hacksaw and just scratch it a couple times, about four or five times around, and soon as you put your finger on, you can feel there’s grip lines through it and that’s what bites the thread seal on. So if you are screwing it into a fitting, the thread seal doesn’t stay where it is, the thread seal stays on the fitting and it turns and it will always have a continuous leak. Now, if you go and put some thread seal on that, do it a couple times round or something, that thread seal can turn. When you have a plastic fitting with a thread on it, if you put your hand on it, you can feel it’s very smooth. We’re probably going to get rid of the valve because we don’t really need it anymore, and just to clean up the hole section. We can get a cover on there or something like that later on. So it’s closer to the house and nice and compact. Once we’ve installed it, we’ll probably put the pump in the location you can see in the video. So in the future, if the pump ever needs to be disconnected, it’s easy to shut off. What we want to do is put a 25 mil isolation valve in there. In the video, we show you the feed that goes from the rainwater tank. Now we’ve got a bit of an adjustment to do. We just got to disconnect the old pump and install the new one. So this intelligent control panel allows simple adjustment to the pressure on all taps.Īnd also the SCALA2 is really quiet, so it won’t disturb your family or your neighbours. This also eliminates pressure fluctuations, and you know what that means? You betcha, lower running costs. So it pumps water out at the perfect pressure to all your taps. ![]() That means that the motor is able to adjust the speed depending on how many fixtures you are using. For you DIYers out there, that’s about 8 Bunnings shopping trolleys end to end. It is self-priming and it can draw a massive 8 meters below the pump. It’s built stronger and it’s the perfect pump for drinking water. Now it has a few more features than his last pump. Kevin has decided to go with the gold standard and he’s chosen the SCALA2, which of course is from Grundfos. The one thing that has caused him problems is the pump. So we have installed all new gutters with slight falls to the new 100 mm downpipes. He lives on a rural property and has no access to scheme water.
