“I used this vent on my home hot water heating system, to replace one that was leaking. I think the nickel plating will keep it from corroding. It is working fine.”
“I use about 10 cutoff wheels a year for my Makita angle grinder and I finally ran out of my old stash. My first task was to cut some 1/2 rebars. These disks are as good as any. No slipping, no shattering, good wear. Great price. As an aside, I bought my first 4 1/2 inch angle grinder about 20 years ago and I can't remember the last time I used a hacksaw outside of my garden. The only disadvantages are you need an electric outlet and safety glasses are an absolute must. Now that I have my new cordless angle grinder, I don't need the power source and I wear safety glasses for everything. Oh - and you must remember that the metal stays hot for a while. Only Superman can make steel get hot when he uses a hacksaw.”
“Simple - Drain your boiler (after closing all the water ) from the discharge valve. Then this is safe to unscrew and change. If you have any doubts, hire someone.”
