How to stablise water pipes under house?

jd15

Hi, 

I have been cleaning out the subfloor of my house and noticed that a water pipe has been secured via a bracket to a rotten piece of wood.
To avoid the risk of termites, what would be the best option to replace this with or does it even need to be secured? 
In addition, do you know why there would be this black tarp under here?

Hi @jd15,

I imagine this was a bit of a rough method that the plumber used to keep the pipe at the correct angle and location. It's not ideal, but if it is working, it's probably best to just leave it as it is or replace it without altering the height or location of the pipe in any way.

If you were to replace the timber, then you should use H4 treated timber, such as a Treated Pine Sleeper or use a material that is not susceptible to rot or insect damage, such as a brick or block.

In regard to the black plastic, it is often used as a vapour barrier, or simply to cover the ground to prevent weeds. Seeing that it is only covering part of the area underneath your house, I doubt it is serving much of a purpose and it could just be leftover construction waste. 

Let me know if you have any further questions.
