I already have a decent plan of atack to correct this condo complex noise problem. Eq. install boiler feed system, insulate main,install heder and pipe equalizer off the end any other input would be greatly appricieated.
thanks jim murtaugh

that oak park problem...

Jim,

>install header and pipe equalizer.

from the photo, yeah, looks kinda iffy.

>install boiler feed system.

appears as if they were thinkin about doing
that and didn't, for what reason, who knows.
is that red valve a flow control or just
isolation? at any rate condesate is prolly
backing up causing that hammer, think so?
( snipped weil's detail, looks familiar don't it )

>insulate main

indeed!

throw in your "designed for service" valve set
( always worth the extra $ ) and their problems
may disappear as if by magic.

may not even have to re-pitch anything upstream,
( maybe ) but don't know that yet?

a shame they didn't find you sooner!

keep us posted;

regards, don

Here goes.

Looks like most of the distribution piping was thought up on the spot. Weil spends a lot of time & money on I&O Manuals. This one makes that look like a waste.

Before you put in a feed water tank: what is the "A" Dimension? If it is 28" or higher, take out the improperly piped false water line & hook it up as a gravity job. Might want to pull that plug valve out of the return, too.

A properly sized & installed header & equalizer is a must. Might be best to take one step at a time. Good luck.

WEIL

"A" demension seems fine planed on taking out that plug valve weil also recomends feed system. i suspect the previous boiler was a big national with a big water chest

RonWHC

We have taken

out 5 feed water/condensate units on Weils over the last few years & piped them gravity. The tanks/pumps were there to compensate for improperly installed or grossly oversized boilers.

Don't know the regs in your area, but in ours, that pump triggers a mandatory daily check by a stationary steam engineer. Why not try the simple solutions first?

Hi Jim,

The near boiler piping is a mess. The supply riser looks too small out of the boiler. The loop on the return is puzzling, what were they trying to do? The plug valve in the return is a bad thing, get rid of that. Don't know if the boiler feed system is necessary. Are you having flooding problems?

I like to fix what I know is wrong first, and go on from there, one step at a time. I don't know if the owner will like that idea, but why do more than is required.

My advise is to change the near boiler piping to Weil's specs and clean up the return line. Skim or chemically clean the boiler water and see where you are at. These are all necessary, so you're not wasting your time or the owner's money. It also might be all that is needed.

Keep me posted. Feel free to contact me with any questions.

Best regards, Pat

question

Hi Ron,

What area are you from? I'm not aware of this regulation. I can see why someone would think long and hard before bringing this type of regulation into their boiler room.

Best regards, Pat

near boiler pipe

the install instructions say that 4" is ok but that 4" goes into a 6" main after the equalizer my thoughts while correcting equalizer and installing a header make it 6" ( wich is the boiler taping) in order to slow velocity and help that steam dry out. any thoughts anyone.thanks in advance jim murtaugh

the plug valve....

may be less expensive than a good quality gate valve to valve off the boiler and blowout the crud build up in the return, it looks like a good place for a drop header setup for the near boiler piping. Changing the "simple" things would be better in the long run than adding a condensate pump set, float controls, make up water soleniod, etc. more mechanical parts .. more troubles. Also, your comment about a smaller steam chest leads me to a couple of thoughts... #1 the correct size (Gpm) of condensate pump to maintain proper water level on startup and #2 the adequate sized condensate tank to collect and hold returning used steam during and after the heating cycle. Just some things to consider.

that's more like it

Hi Jim,

I think it is an excellent idea to go "full size" from the LGB 6" supply tapping to the existing header. This will slow velocity and by theory, have drier steam leave the boiler and maintain a steadier waterline.

I've been away from the 'puter for a couple days. Work in Washington, D. C.

The requirement for a Stationary Engineer/daily check for all pumped condensate boilers has been a requirement since the Army Corp of Engineers ruled the roost. Boiler size does not matter. The pump is the trigger. Fine is $500. p/day.

i belive this is only required if there isnt a low water c/o or city water feed line

[Deleted User]

Jim.

The requirement here is in addition to all of the other local codes & CSD-1. Your LGB-8 would require 2 LWCO (1 testable w/ manual reset)& Manual Reset Safety Limit Pressuretrol that is wired directly to fuel valve circuit, not thru the limit.

Funny thing is, the school engineers can't keep their boilers from becoming glowing piles of slag.

thanks for the info

Hi Ron,

Does this apply to the District of Columbia only, or the states of Maryland or Virginia? Thanks for the information.

Best regards, Pat

Dave Meers

thanks

Hi Jim,

I did some calculations on the velocity. At start-up the 4" causes a velocity of 59 feet per second. I don't like anything over 50 myself. I think Weil is cutting this pipe size on this boiler too close. If you pipe it in 6" the velocity slows to 26 feet per second. Nice and slow, just like the oldtimers wanted.

On a personal note, thank you for purchasing the field guide. You should be receiving it by Wednesday.

Best regards, Pat
