Need to replace big old galvanized pipe with pex
Hi, I own a 1300 sq ft 2 story farm house from 1929 with an unfinished basement. I want to finish the basement but some of the boiler pipes are hanging low and are huge. I can tell the old owner had a gravity boiler at one time and did not want to pay to replace the pipe running to each of the radiators, so they left the huge 2 & 3 in galvanized pipe running under the first floor on the basement ceiling. These are the pipes hanging low that I want to replace. The old owner also replaced the huge cast iron radiators with baseboard radiators that are 1/2 inch copper. Also the galvanized running to the second floor is 3/4 inch so I do not want to replace this and avoid opening my walls. My boiler is a gas burning 10 year old using 1 1/4 inch copper pipe. My question now is, can I replace the large galvanized pipe with 1 inch pex barrier? So I would have 1 1/4 boiler pipe attached to 1 inch pex to all of the 1/2 copper radiators on the first floor. The same 1 inch pex would attach to the 3/4 galvanized running upstairs which are attached to the same 1/2 copper baseboard radiators.
