@ March 16, 2014 5:13 PM in Myson 7000 toekick heaterThat particular tee is piped in correct but I would change the orientation of the return.I usually pipe the toe kick in with copper and leave a bleeder valve on inlet.If it doesnt work I would suggest as the others have said to install a globe valve and throttle the flow.good luck with it
@ March 7, 2014 10:15 PM in Beating a dead horse.over the last year I installed 8 burnham ES2 and one ESC.Of the eight ES2 6 had to have their pilot assemblies replaced and also the ESC.Whats your thoughts Harper on this great brand.
@ March 6, 2014 9:38 AM in Free solar ???????i got a letter from a solar company saying they will install solar panels for free and instead of paying utility company you pay them the bill.Im in long island company is RGS
Is this to good to be true or where is the catch
@ March 1, 2014 8:08 AM in New Gas ConversionThere is a member here when he sees oil to gas he automatically assumes the plumber is going to take the oil burner assembly of and replace it with a model that is gas fired.As Steamhead has said when done Properly there is no issues hence the word properly as many guys cant do it right.Repost on the main wall,you might have more luck.
@ February 26, 2014 7:06 AM in Venting mod con up a (lined) chimney flue?i use the chimney as a chase all the time with centrotherm.I just watched a program(this old house) where the plumber used the chimney as a chase but also using centrotherm used the chimney for his fresh air intake.That i have never done and was curious as to whether any one else has.
@ February 25, 2014 7:12 AM in Not again! Carbon monoxide kills one, sickens 19was it a flue pipe came apart.? just shows how important it is to follow safety guides.
thoughts with the family,so unnecessary

I enjoy reading your comments and advice,Thanks
@ February 25, 2014 7:03 AM in when to use NPT and when to use sweatgood for you at least you are using isolation flanges.I havent had problems with Taco flanges although I do prefer the Grundfoss model.Use solder if you are piping in copper or some people like to use blk fittings then go npt,good luck.
@ February 24, 2014 7:23 AM in manifolds in series?I actually had a friend suggest that to me.I am certainly going to bring it up .Again there is three remote manifolds.I think a total of 27 actuators.Every balancing valve is clogged with a rest color.Is it possible the non barrier pipe is responsible for this.I am going back tomorrow and will take pics.I really apreciate your responses.
@ February 23, 2014 11:07 AM in manifolds in series?so we went back to the scene of the crime.Condo board want us to start on duplex apt.We got the design layout from viega which helped in locating hidden manifold.so every balancing valve is filled with a rust color and does not work.Heating side of boiler one set of closely spaced tees (8inchs apart.)These support four manifolds covering 3200 sqft.In the cellar on a six loop manifold,3 loops have viega pipe other 3 had a blue color pipe which we discovered was not o2 barrier.we figure the non oxy barrier pipe is causing system to rust,there is a lot of ferrous material on near boiler piping.We want to eliminate infloor heat in cellar and run radiant on walls.(very expensive Tile floor).we want to avoid ripping it up to run proper pipe.Im babbling.Next week we go back,I will take pics ,again thanks for your interest and help.By the way it is not an open system and all manifolds are piped in parralel if I understand corectly,

@ February 11, 2014 6:54 AM in Hot Rod,caleffi hydro air seperator vs p/s pipingthanks for sharing,nice work.
@ February 9, 2014 8:48 AM in Hot Rod,caleffi hydro air seperator vs p/s pipingIm giving consideration to scrapping p/s piping and using caleffi hyronic air seperator.When I use p/s I have a primary pump,spirovent,dirt seperator,pipe and fittings.Does it make sense use the low loss header,mainly for space issues, and when you break it down there isnt much of a difference in $$..Thanks John.
@ February 7, 2014 7:17 AM in Lead generationI tried one of those companies.For the first 2 weeks plenty of leads.When customer answers they are confused by how many plumbers are calling them.I am done with it.I heard this site is great for advertisement which i am planning to do .For a start up company like me its hard to break into the market and compete with established companies.Good luck,John.
@ February 7, 2014 7:13 AM in manifolds in series?Definitly electric water heater,I know it sounds hard to believe.we want to put in a buffer tank to prevent short cycling but the boiler room is so tight there is no room.we are going to disconnect electric and make it into a storage tank wit circ,aquastat and flow switch.
This system has been over complicated as some reps got in there and sold a lot of equipment which made an easy install into a mess.Original plumber walked out on job.By the way this is one of five manhattan apartments all experiencing the same problem.Mark,would you ever put in a 12 port manifold?In my eye it just seems so hard to balance and get flow through all loops.I will take pics when I go back in a few days.Again thanks for your help as always,John.
@ February 6, 2014 9:42 AM in manifolds in series?Hi Mark and thanks for your time.NTI 200 combi backed up with 38 gallon electric Rheem water heater.
Heating side.11/4 primary loop.Closely spaced tee 11/4x1
Supply goes through Viega enhanced mixing station.Viega spceked a 12 loop manifold.Plumber put in two six loop manifold.I guess I am wrong and piped parallel.I got my terminology wrong.ON the mixing station when I opened the purge screw on pump I got no water.Nti rep says system is airbound.He didnt like the piping arrangement but thinks it will work.By the way the apt is 1200 sqft.heatloss is 25k.Boiler mminimum firing rate is 55k.
NTI said its a good boiler but wrong application.So 2 yrs later tennents are still cold.Even if it is airbound do you think I should build a header and split manifolds.
Domestic side I am going to redo as to manufactutres specs.
I apreciate your help ,John
@ February 5, 2014 8:53 AM in manifolds in series?I came from a call today.A combi boiler in a 1200 sqft apt.Domestic water goes through an electric water heater then to fixtures.(customer complained of nhigh electric bills).On the heat side there is two six loop manifolds piped in series all with actuators.Radiant piping is minitube.Has anyone ever had success piping two manifolds like this,by the way there is problems with heat in every room.Thanks
@ February 3, 2014 7:24 PM in Rule of thumb for btusI have heard lxwxhx4 will give btu for room.havent tried it but I know someone who swears by it.Give it a try and let me know how accurate it is
@ January 30, 2014 10:51 PM in Copper Riser Piping and Supportbelieve it or not ny state allows m copper on potable water.
@ January 30, 2014 9:00 AM in alliance running coldyou need a minimum of 1" piping and if using grundfoss use the 26-99.
@ January 26, 2014 12:41 PM in What brand of indirect hot water heater would one recommend ?it depends on water quality etc.A respected guy on this forum suggested either budures or Burnham alliance.I choose the latter but you have to allow for a larger head loss in tank.I has to use a Grundfoss 26-99.No complaints so far..
