Non-copper pipes - I assume you mean galvanized, and I assume you are not on a well system.

In your place, fefore spending $1000-2000 or so, I would check your incoming water supply. If you have a faucet near where the water comes in, I would check if full-flow water from there (say into a 5 gallon bucket) also has sediment or particles. If so, then it could be your incoming water pipe is the problem. I would also check the flow rate there versus say at a sink - if dramatically more then probably corroded interior pipes, but if similar then maybe the incoming pipe is the problem, or a plugged strainer or filter if you are on well water.
Also, at the tub, run cold and hot water separately to see if only the hot has particles in it - if so, then the hot water heater is probably the culprit.

All these can be checked by a plumber for about $125 - for only another $25-75 he could break open a couple of unions to look inside the pipe for corrosion. Granted, if corrosion of the galvanized pipes is the problem then that inspection money is wasted, so obviously your call, but I would personally want peace of mind that I actually fixed the right thing. It would really hurt to replumb the house and then find the incoming main was the source of the problem.

I remember in my parent's house in Malibu (build 1952) every 20 years the 2 inch galvanized water main needed totally replacing due to severe internal corrosion and iron deposit buildup to about 1/2" opening, but after 40 years the interior house plumbing (except the water heaters, which built iron slime) actually did not look bad, and had developed no breaks except those occurring immediately after significant earthquakes.
