Right, watering the plants should be a straightforward thing if it wasn't for the fact that the main tap has been located under the deck in our house.

Every time I need the hose I need to open up the hatch, kneel down and stretch, turn on the tap and then I can finally water the plants. Doing this on a daily basis is starting to get a bit tedious so I've been exploring alternatives to avoid this problem.

Exhibit A

In an ultimate world you would remove the tap and relocate it to a higher spot however we're renting and I am trying to find a low cost solution.

I thought I was clever and went to Bunnings and obtained a few parts to attempt to extend the water point.

I got the following two way splitter: https://www.bunnings.co.nz/mcgregor-s-2-way-tap-adaptor-with-shut-off-brass_p00947315
and was hoping that it would allow me to control the flow whilst having two hoses connected.

As soon as I open up the tap and twist it more than two times round water comes spraying out of the top of the splitter. I have tried various connection pieces (mostly brass) but whatever I do the pressure seems far too high and a leak will appear somewhere in the chain.

I've spent approx 2 hours talking to various staff members at my local Bunnings and they can't come up with a solution that will work. I've also looked at shower hoses (metal ones) in the hope that they would provide a sturdier connection however they don't seem to be the right size.

Is there any reasonable way I can extend a water tight connection to the top of the deck so I no longer need to use the hatch?
