Installation Guide for AQUAMISER
Greenhouse System


Contents of your System Pack

3xEnd Stops (B), 2xT Connectors (C), 4xStop Valves (D), 4xElbow Connectors (E), 1xOverhead Spray Assembly (F), 10xMini Drip Assemblies. 10xTube Supports, 5mx4mm Tube and 10x4mm Connectors (to make extensions for Mini Drips), 50xBlanking Plugs, 50m Supply Tube (A), Straight Connector to water supply and Installation Tool (ie the pointed end of a spare Tube Support)

In addition you will need:
1. a Stanley-type knife to cut your supply tube
2. a kettle or pan of hot (not boiling) water to soften the supply tube when connecting fittings.

Suggested layout This typical installation controls the water flow to separate sections and enables the supply to each to be adjusted or turned off as required. The components included in your System Pack (excluding the connector for your garden tap) will allow a smaller version

See Components and Prices for further information or additional items to extend your system

IMPORTANT AQUAMISER and most other brands of fittings for 0.5" (13mm i/d) hose are of the push-fit ("barbed") type. If your main water pressure is higher than 28lb/in2 (2 bar or 2kg/cm2), barbed joints may not be strong enough to withstand it. Regulate the pressure at the tap and/or secure the hose fittings with jubilee-type hose clips

Planning your System

This System allows two different types of watering:

  • Sprays for misting or damping down
  • Adjustable Drips for individual plants in beds or containers

You need to organise your supply to allow you to turn off the Sprays whilst leaving the Drips running by setting up the Sprays on a branch of your supply to which the flow can be turned off. The layout shows an example

System performance will depend on water supply pressure, the length of supply hose and the number of components fitted. Install your system progressively and observe it in action!

Setting up your Water Supply

AQUAMISER Sprays need a pressurised water supply. You can provide this by

  • using a static tank with a pump installed between the tank outlet and your supply hose
  • attaching the hose directly to a garden tap

Drips need lower pressure. In pressurised systems you may need to restrict the supply to Drips to avoid jetting or forcing the adjusters out of their housings. Using Stop/Control Valves (875) will provide a means of control

Set up your system to supply the Drips through one Valve and the Sprays through a second (see diagram). You can then use higher pressure to enhance Spray performance

Ideally you will use a water tank to recycle domestic grey water (from bathing or washing up etc) or collect rainwater, and use this with a pump to supply your system. With very few exceptions, you will need to pressurise the supply. In the UK you must use an anti-siphon valve to prevent contamination of your domestic water supply when connecting a hose to a garden tap supplied by mains water. The valve is often incorporated into the tap connector and these are widely available at garden shops. If using a water tank fed from the mains there must be a proper air gap, again to prevent contamination. We suggest you contact your main water supplier about regulations applicable to your area

Installation Step by Step

What to do

AQUAMISER Tips

1

Decide on the layout (see diagram as a guide). Assemble the tools you'll need and obtain any additional fittings required (see again IMPORTANT above)

You can use any 0.5" hose to bring the water to the start of your system. Use the Straight Connector to join this to the AQUAMISER Supply Tube

2

Lay the Supply Tube around the area to be watered. Cut the Tube and insert the fittings (T or Elbow Connectors, Stop/Control Valves etc) where you want them. Soften the Tube end first in hot (not boiling) water before pushing the fitting home. Continue until all Supply Tube is installed as required and seal the open end(s) with an End Stop(s)

AQUAMISER Drip Assemblies can be positioned within about 15" radius of the point of connection to the Supply Tube, so this allows considerable flexibility. Make Supply Tube joints smartly and allow to cool without moving. The Tube will shrink around the barb on the fitting. Instead of End Stops you can just bend the Tube ends over and tie closed with strong garden wire

3

Install several AQUAMISER Assemblies at strategic points. Make a hole for each in the Supply Tube with the Installation Tool. Soften the Tube at the point of connection with hot (not boiling) water and gently push (whilst turning) the Connector for each Assembly into its hole until properly located

Do not overwork the hole. The connection needs to be a tight fit to avoid leaks. Make the joint smartly then hands off, so that it firms and seals as the tube cools down

4

Turn on the supply and observe the delivery of water . If there are leaks at any of the Supply Tube fittings, remake them (using hot water again) until you get them right, or secure them with hose clips. Connect all the Spray and Drip Assemblies at their appropriate points along the Supply Tube. Make up 4mm Tube Extensions as required to position the Drips where you need them

If you have made any of the Connector holes too big, seal them with a Blanking Plug and try again. There is a knack to making connections but you'll soon pick this up ... You are far less likely to experience Connector leaks if you use AQUAMISER Supply Tube as the Tube wall is both rigid and thin and you will make cleaner holes, so the Connectors seat properly on the inside

5

Drips can be used either in the ground or in containers. Set the flow to the desired level by turning the Adjuster whilst gently pulling it out (to increase) or pushing in (to reduce)

You will feel some resistance as the Adjusters are designed to fit tightly to avoid their being forced out under water pressure

6 Once you're happy with your installation you can conceal any exposed Supply Tube by mulching. This also helps protect it in extreme weather conditions

7 Should you need to remove a Spray or Drip, soften the Supply Tube with hot water, grip the Connector gently and rotate and pull at the same time. Use a Blanking Plug to seal the hole in the Tube

8 Provided that the supply is clean, your AQUAMISER watering system should require no maintenance. If dirt gets introduced you will need to dismantle the Assemblies to wash or blow it out

9 In hard water areas a build up of deposits is unavoidable. Immersing Drips in descaler solution will clear this
