OP Andy, can you tell us about that rainwater collection system that you've got there? How big are thanks? How much water do you collect? How is it used?

Thanks.

@Z -- we got 55 gallon rain barrels around the building at work. It rained very briefly over about a week ago. Not torrential or anything, just a light sprinkle. All the barrels went from bone dry to overflowing within an hour.

Question for OP: Do you have a regular hose bib attached to yours? If so, does it have a decent flow rate? Because on the barrels we have at work, the water just trickles out with the bib fully open. The barrels have a screen on the top where the gutter feeds it so the bib isn't obstructed (to my knowledge...) I was thinking maybe it needs a carb or something to even out the pressure? I would've thought the water would come pouring out with all the weight, but no...

The guys at the hardware store said it'd be fine before I started and the videos I watched before commencing pretty much reenforced what they said at the hardware store. So I went with that.

What I need to know is, is there anything I can do to repair the posts I have or do i leave them?
The hardware folks and the vid generating people, bless their pea picken hearts, were hired because they know how to operate a computer and that's about it.

If the lumber you purchased was moisture tested we would find a percent of moisture somewhere upwards of 25 percent in my estimation.

So why did the posts choose to split in the most unsightly location at the visible end? They split there because there are 2 exposed edge surfaces to dry plus the end which caused dimensional stress of the width. ie, the advanced drying there pulled it apart. The two face surfaces of the wood didn't matter much concerning drying rate. If you were to remove a post you would probably find the split stopped not too far below soil surface because of soil moisture.

To avoid this the lumber would need to be an estimated 6-8 percent moisture when installed and then if moisture was increased from exposure it may bow between bolts.

In my opinion this is expected in our modern high speed society and it looks just fine and very normal.

There's almost always going to be one person with some scathing comment even in a diy help type forum, forget about it. The wall looks good and I'm sure will last quite a while. When it starts to rot in the future, just replace it with retaining wall blocks and you'll never have to worry about it again.

As far as the splits, it looks like the wood was still pretty wet when sunk in concrete and the concrete curing sucked the moisture from the wood causing it to crack. It's not going to do anything to the structural integrity of the wall though.

Looks nice with those bolts. Good job.

Thanks JustScrewIt. I didn't think it looked too bad. It's an outdoor area for the man cave inside. The plastic wood putty is a good idea. Thanks for the compliments.

Thanks.
The rainwater tanks hold 3000 litres. It is a requirement that we have water tanks off our sheds. (depending how big the shed is though) Council requirements. The water in these tanks will be used for washing the cars, gardening etc.

I've just connected a water pump to the tank with tap. Water pressure is strong. It wouldn't be though without the pump.

That's one helluva man cave. Tim The Toolman Taylor would be proud!
