is 'Heating Contractor' a 'hvac' person//company?

this site doesnt list ppl by 'heating'

are there any sites on the Web that organises ppl by 'heating' cos google maps doesnt

tried google maps 1 time, and it showed/listed ppl that wasnt what you searched for

also any good ways to search by if ppl go to a certain area? cos this site only lists ppl that goes to certain areas but it doesnt tell us where or how far they go to

This sounds like the water feed for a steam boiler. If that is the case you need to call a HVAC company which services steam boilers. Where are you located?

yea its 'steam boiler', plumber said it makes steam, so i guess it's 'steam boiler', that uses gas + water + heat to produce the 'steam' dont know

when was brass pipes invented? brass pipes you can get at home depot etc

cos these pipes were 'cast iron' and seems like end of the pipe connected to water tank/heater got rusty

i dont know why this old house used 'cast iron' pipes if it can cause this kind of problem

seems like it would've been prevented if it was brass pipes connected to water heater/tank instead

doesnt seem like brass pipe would be a new invention, dont know why 'cast iron' would be used, and nobody ever updated the materials used in this house over time....

Houses were built 80 - 100 years ago used galvanized iron pipes. They may last 50 years built eventually they corrode from the interior. Connecting directly to a brass fitting on a hot water heater is going to speed up the process. Replacing all the plumbing in a old house can be expensive.

Brass pipes are very expensive and I guess they were back in the day. All the plumbing in my 1895 house is copper, but when it was built, there was no indoor plumbing. There was a major rehab in 1952, so maybe that's when they put in the copper piping.

boiler person said this problem was related

the hot water from the boiler is mixing with the clean drinking water...

dont know how long this has been going on for....

and since the dirty water was mixed into the clean water, it seems like over time the hot water worn out the pipe that lead to the water tank/heater

Re brass pipes used in plumbing. After the war, there were building material shortages. A large area of Redwood City, CA was plumbed with Navy surplus brass pipes.

It was known the brass pipes had a relatively short life span, IIRC, 40-50 years.

I drove by the area with a plumber who installed brass pipes, he told me the story. I think the development was called Fair Oaks it was south of 5th Avenue.
