New house old radiators leeing water fron vents

Jason_26

I found these http://kingsolar.com/catalog/mfg/maidomist/1straight.html but i am not sure what size to get how can i measure the holes that are already plugged or should i just retap new holes. also on the main there is only vent holes on one end and the other end has aspestas on it for insulation. does it have to be right at the end of the line or can it be down further say a feet or 2 from the end?

radiator peeing at night

I just bought an older home with a 1-pipe steam heating system. the furnace is brand new and the radiators are not. after having the heat on for the first time i noticed the radiators were leaking from the vents. so i found out that the radiators need to be tilted. ok thats done but now the radiator in the master bedroom likes to pee at night when it is on and the others get some drops coming out of them nothing to bad but the one in the bedroom really makes a mess if the bucket is not there. i am not sure how to stop this from happening it is on the second floor and is normally the last one to get the heat to it by a few seconds. why is there water coming out of it. also they all whistle when the heat is on and i did have to replace 1 vent and possible more but one is new but it still gets loud and i get alot of water hammer too. I need help i cannt sleep at night because everytime the heat kicks on i wake up to make sure the radiators arnt flooding my house.....

A couple things...

to check.

1. Make sure the supply valves on your radiators are COMPLETELY open. If they are old, you may have to disconnect the radiators and visually inspect the valves to be sure. Turning them counter-clockwise until they no longer turn does not necessarily mean they are open all the way.

2. Check your pressuretrol settings. The boiler should run on no more that 1 or 2 pounds of pressure.

3. You've checked the radiators for pitch, next is to check the supply pipes in the basement, crawl, etc.

That's where I would start.

well from the looks of the pipes they are pitched right but my next question is the main in the basement someone removed the vents and plugged the holes do i need to put the vents back in? will that help with the water problem or the water hammer i get?

you said the boiler is new...has it been cleaned out on the water side and skimmed...dirty water will get the vents to spit...kpc

Hold on a sec... I doubt those are what you want.

Post the length of your steam mains, and their sizes (diameter in inches)... Steamhead and a few others here can calculate how much venting you need on your mains..

I believe Gorton sells the best main vents... you can buy them online at pexsupply.com, or through a local plumbing supply shop.

As for the location... ideally, they should be a foot or so before the end of the main, but I often see them mounted at the end (including on my two pipe steam system). The idea is they'll get damaged more easily by water if they're mounted at the end...

If your system originally had vents, but they've been plugged up, just remove the plugs and install the new vents. No need to re-tap or re-arrange...

ok now how do i measure the main
one pipe comes from the furnace and goes left and right near the wall to the right no holes for any vents and to the left there is 2 holes plugged right now
so to measure it i measure from that t left then right or the lenghth of the whole thing? and just so i know why would those not work?

Jason_26

one more thing i dont know if i am going to get those plugs out that section of the pipe is very rusty i think there used to be a leak near it the pipe doesnt leak now but i dont think the plugs are going to come out plus they are right at the end of the line 1 points straight up and the other points to the top side. do i need to put 2 in there or just one?
