Tying down PEX tubing ?

[Brad Littlejohn]

It is really necessary to tie down PEX every 4 feet? I am replacing PolyB with PEX. The previous plumber tied down Poly B all over the place. I had to make a lot of holes just to cut the tie downs.

Most of other run goes through floor joists (working on the plumbing on the second floor of a two story home)

I was reading on why the pipe was tied down so much and it has to do with friction from the pipe heating and cooling. But, I look for sample pictures of PEX leaks caused by not strapping down the pipes and could not find any.

Is this a real problem?

I think it is 32 inches for horizontal PEX supports, but the supports would not totally restrain horizontal movement.

for a small material cost and admitedly a few more hours more of labor you could have system last 5 or 10 times as long, by doing it right. Id say do a little investigation on strapping , hanging materials, be dilligant about straight cuts , look at every single fitting for nicks , try to be aware , all of these things matter, also be carefull dragging pipe across nails, a lot of things can go wrong but the watchful eye catches most
