DIY watering wand

I like to water my plants with a sprinkler type watering head. The problem is we have very hard water. If the holes plug I will use a small drill bit to make it work. At least twice a year the ball valve will break, and the way it's made it can't be repaired.
The other day my son was asking why I wasn't using one and I told him It was broken. The next day he made me a watering wand. It's wonderful. A good size.  Enough water volume without being to strong. We had all the parts, so it didn't cost anything. I think as my other ones fail I will make more DIY wands.

This is brilliant!  What a wonderful design. Beautiful veggies too!

Your son's done you a great service - good outside-the-box thinking!

Your prototype is what you had on hand and there's nothing wrong with that, but knowing what I know from my own hard water, I wonder if/when you make more, you might want to consider the two end caps being held on with small stainless screws, rather than glue. That way you can take them off and run a brush through to help you clean out the gunk.

Soaking it in a strong vinegar for a few hours before brushing it out will help even more if your hard water is anything like mine!

Atta boy!!!

This is one of those things where you go, "why didn't I think of this years ago?". Probably cause I am not as smart as your son.

Genius!

Instead of screws, or glue, maybe just use screw on end caps? To be honest I have that same amazing norcal water and I can always seem to get the holes opened back up without dissecting anything. However, this may be because all my wands break before they get too old and clogged...

When the holes get clogged, I will use the drill.
Thanks everyone.
