A new house and a new, much larger, garden made the auto watering consideration a must if we were ever going to have time to do anything other than spend 3 hours a night watering all those lovely hanging baskets, vegetable plot, greenhouse etc.
After learning what was required for the system it became apparent that the 4 way tap connector was a must with only one outside tap available!
The 4 way connector comes supplied with it's own wall mounting bracket which is very straight forward to fit, the barrel that comprises the connector outlets then slot on the bracket and snaps in to place. The whole barrel can be easily taken off the wall at any time. You have the choice of connecting a hose from your tap to either the left or right side which is very useful. Once connected to your garden tap the idea is to leave the tap in the on position. From there you can individually operate each of the 4 'extension' taps via a control knob fitted to each extension tap. I used a hozelock connector for the garden tap end and the whole unit works perfectly without a single leak!
I have fitted a watering computer to the far right extension tap, this comes on once a day at the programmed time and then shuts itself off. During this time it's not possible to operate any of the extension taps unless disrupting the auto watering pressure. If you want more than one computer you will be able to fit 2 to this extension only, however be warned - you must set each computer to come on at different times in order not to disrupt the water flow!!
I use this with one computer, the garden hose permanently attached and the other two outlets as spare for filling up watering cans etc. the plan is to fit a 2nd computer for the front garden next year.
The only slight niggle with this unit is that the tap knobs are a little fiddly to operate and are a little stiff. However the whole unit is super water tight and well made. At £17 it's not that cheap but when compared to other watering system manufacturers it's definitely miles ahead in terms of quality.
Water, water everywhere That’s all we gardeners seem to have to do whenever [ifever?] it gets sunny, and there is only so much that can be done with water butts and cans. If you use an automatic watering system hooked up to an outside tap, as I do, you’ll know how aggravating it is to have to turn the water off, disconnect / reconnect, turn the water on again, just to use a hose, then do it all over again to leave the automatic system connected afterwards. The expensive answer is to plumb in an extra tap or two, the easiest answer is to install a Hozelock 2150: a four-way, individually controllable water supply. As with all hozelock stuff, it comes in a yellow grey plastic combo, that appears robust, nicely finished and well thought out. Water goes into the manifold via a port at either left or right through a short length of dedicated hose which remains permanently connected to your outside tap: the connectors for this are supplied with the manifold; you have to supply the hose- I used a short piece from an hose which was ruined further along its length where it had got frosted. The manifold push fits onto a bracket which screws onto the wall- the packaging card has a template to ensure you drill them in the right place. That’s it Once the manifold is on the wall, the supply hose connected, and the water turned on, you’re ready to go. Up to two automatic timers can be left permanently connected, as well as a hose or two for washing cars, lawn sprinkling etc. Each outlet has its own control tap, which can be opened part way if you don’t want so much water delivered. The control taps seal with a rubber O ring which should be good for some years. All in all, I consider this well thought out, and very useful if you use an automatic watering system- the ease of access that we take for granted in our houses with electricity, is now becoming available
in the garden with water. The only obvious downside is that you might use more water, though I would say that the precise delivery given by an automatic system actually cuts the amount needed, especially when combined with mulches to reduce water loss. UPDATE June 2001 I've now connected a second auto irrigation system for the back garden and greenhouse, and a wall mounted hosereel. Everything is a lot tidier, and much easier to use. I now have just the one tap not spoken for. . . .
Allows the water supply to be divided in up to four outlets including up to two with Electronic Water Timers
