Superhead Installation Guide

Overview

The Superhead needs to be installed above the inlet to your tank. The inlet can be the top of the tank (shown) or can be through the overflow pipe on the side. The overflow pipe is a good option where height is an issue.

The Superhead can be installed anywhere between the gutter downpipe and the rainwater tank. It can even be installed directly on the tank. In this example it is located directly under the existing downpipe adapter.

The Superhead will shed leaves from the gutters and also drip as the flush pipe drains so select a suitable location near a garden or drain. Alternatively the flush pipe can be connected to standard reticulation fittings to direct the first- flush water.

You will also need to secure the Superhead and pipes to a wall or other structure. It can be fixed to the rainwater tank but be sure to only put screws and fixings above the water line, or on the stand or otherdry part of the tank. DO NOT FIX DIRECTLY TO THE TANK OR YOUR TANK MAY LEAK!

Instructions

1. Roughly position the Superhead where you want to install it and check for a small fall toward the tank, secure mounting position and also length of flush pipe required.
2. Remove or cut the existing downpipe at the required height. We recommend a square cut (not angled) as this allows water to distribute over the leaf screen and allows room for the leaves to disperse. If the cut is angled and/ or too close to the leaf screen it can trap leaves.
3. Cut a length of 90mm PVC pipe to use as the flush pipe. The length should leave around 150mm clear at the ground
4. Insert the rubber funnel into the bottom of the Superhead and insert the flush pipe. the flush pipe will hold the funnel in the correct position. Secure the flush pipe with the small stainless steel screws provided.
5. Attach the base cap  assembly (joiner, cap, drain plug and filter foam) to the bottom of the flush pipe using pipe cement or silicone.
6. The side outlet can be rotated 360°. You can change the outlet position by removing the 4 small screws under the leaf screen. Select the required position and insert the screws.
7. Now is a good time to paint the assembly (if required). If painting is required then prime the surface using acetone or PVC primer. It can then be painted with most standard paints. Wait until dry.
8. Position the Superhead assembly in the correct location and check for vertical alignment. Mark the position of the two top holes and secure the Superhead to the wall or structure
9. Connect the pipe inlet tank to the Superhead side outlet. Use PVC cement glue if required.
10. Insert the fine filter into the side outlet so the mesh faces back into the Superhead (see picture)
11. Secure all pipes using pipe brackets

Congratulations! Your’e all done!

Adjusting the First Flush Diverter

If it has not rained for some time then your roof and gutters will contain a lot of dirt. Therefore you may want to do a large flush to clean the roof before collecting water. To do this simply loosen or even remove the drain plug at the bottom of the flush pipe.This will allow more water to be ‘flushed’ before it gets diverted to the tank.

Alternatively if it has been raining frequently you may wish to reduce the first- flush. To reduce the flush simply tighten the drain plug.

The flush pipe will slowly drain through the plug over the hours following rain. It is important that the flush pipe empties otherwise water can stagnate in the flush pipe. The foam filter prevents debris from blocking the drain but check the drain plug occasionally to ensure that it drips after rain. If it is not dripping simply remove the drain plug to clear any blockage.

Cleaning the Insect Screen
The fine mesh of the insect screen prevents insects and fine debris from entering the tank. The design of the filter is self cleaning however certain debris like flower stamens, pine needles and other long fine matter have been known to get stuck in the mesh and restricting the water flow.

To clean the mesh, simply remove the top leaf screen and remove the insect screen to remove any blockages

If you are experiencing blockeges frequently then you could try a filter bag (contact us to buy). Alternatively if you have another insect screen such as a basket filter on the top of the tank then the insect screen can be removed altogether

You will need the following

• Threaded micro joiner (those little joiners to connect micro pipe to 19mm)
• Adjustable Dribbler
• Length of micro irrigation tubing
• Drill and 4mm drill bit

How to connect to reticulation

1. Drill a 4mm hole in the base cap.
2. insert the micro joiner
3. Attach the pipe and dribbler
