Re: Combustion air for a boiler...finishing a basement
When making a enclosed mech room aside from make up air which if the basement is semi sealed a fan in a can should be added a louvered door for a 175 btu boiler sounds like a general contractors way of keep cost down which personally is not ensure proper combustion and safety for you and or your equipment nor your safety and proper operation of your system when it s winter and everything is closed . Not to sound like a tool you will likely not find many hvac contractors who even have a clue about combustion air you have to find some one who is familiar w combustion and codes . I known this due to being in the business and in talking w many in the business I’m always amazed at how much most do not know usually because most care about one thing and that’s making a ton load of money plain and simple , the rest of it and the work is the means for the money .
Also in closing your mechanical room be sure to leave enough room for future replacement and service other wise as nice as the finished basement is not many service or installation guys will enjoy working thought it and usually replacement cost are higher on finished basement then a non finished just goes to reason . I know I charge more for replacement on finished basement more time more drop cloths and usually less room and more cleanup .
Telling the truth reguardless of the out come peace and good luck clammy

Re: Really Weird P-Trap Config: Is This A Problem
Drains really fast?
I just don't like standing in water when I shower.
Re: Really Weird P-Trap Config: Is This A Problem
Thats not a P trap, its an S trap.
Really? S-traps have no vents. 
Increasing the size of the drain prevents self-scouring, but I sure like a 2" p-trap on my bathtub.
Re: Really Weird P-Trap Config: Is This A Problem
clammy said:Messy primer guy It will suffice being it looks like short turn vent ells glued together most likely not enough room for a solid trap due to poor planning .I do hope that’s 2 inch being code around my parts and the riser should be over 24 if correct.
Not sure about all the terminology but the long pipe from the bottom of the drain box to the beginning of the crazy trap is about 19 in.
The two elbows at the bottom are vent 90s. That is what concerns me because I am worried about flow volume. All of all of it is 2" PVC and it is all glued but he is not a big fan of primer.
He is 79 years old and has been doing it a certain way for a long time. I don't have many complaints about a 79-year-old who comes to work everyday in cowboy boots and puts in a solid 8 hours of plumbing. However, I think he is getting tired by the end of the day and some of this stuff seems a little sketch.

Re: Axiom mini feeder question
Taking a shower should have no effect on the pressure in the coil/ hydronic side of the system. The Axiom gauge should not move.
The pressure in hydronic system, assuming no leaks will go up and down as temperature increases and decreases. It has to, as water is heated it expands. This expansion pushes against the diaphragm in the tank an as it does this gauge will rise.
Here are tables to show that concept. If you want to know that much?
Also a link to a You Tube on expansion from a former Amtrol trainer. At minute 1:08 he explains why pressure must go up as water is heated in a closed loop system with a properly sized and pressurized system.

Your tank needs to be removed from the system. An air gauge to check and adjust to the pressure the on that air stem at the end of the tank. Set it to 12psi.
then set the Axiom to 12psi.Axiom will fill to, make it 12 psi.
To use these charts:
We can allow hydronics to rise to 27 psi typically, 3 below below the relief valve setting.
So with the acceptance chart go from 12 psi fill to 27 max.pressure and the factor is .36, 36%.
So at 27 psi the tank will have 36% water in it, 64% air.
When the system is at 12 psi,and the tank was charged to 12psi, there is no water in the tank!
Next table shows acceptance volume, what size the tank needs to be based on how much fluid is in it.
Assume your system holds 30 gallon. Temperature goes from 50- 140F.
.0149 is the expansion factor.
In a 30 gallon system is is 30X .0149= .447. the smallest tank you can buy is a #15, plenty for a small volume low temperature swing system.
If you can valve off the Axiom from the system and pressure continues to rise and pop the relief, it could be the Axiom pressure valve is bleeding by. It keeps allowing a trickle of water into the system.
Or I would suspect a pinhole in the coil. So tank water pressure, maybe 60 psi? is crossing into the hydronic side.

Re: Should I replace my well pressure tank? Pictures of inlet
2 drops a day is really low for an actual leak in my opinion. Any time I’ve had a leak on a connection like that it has been immediately noticeable and not something that needed attention years down the road. A leak is typically beading up every few seconds to a minute tops. If it’s tight it’s not going to bead at all once condensation is eliminated. Hard to believe you are leaking two drips a day
Re: Steam boiler question
Thank you very much for all the advice I would love to go new but with being broken and broke I have to put things back together and do what I can with the little I have. We are all being chased off the island if your not rich and I'm just trying to survive the last years. Have a good one and thanks all for the info. I did send mad dog 2 an email.

Re: Apartment too hot, no control over heat
If one of our tenants had to suffer through 90+ degree heat in the winter and open the windows and use fans, I would do everything possible to fix the problem. Unacceptable. I'm assuming you're not exaggerating the temperature btw...Have you measured it? If it really is that bad, your landlord really should take action. This is not yours to solve. You pay good money every month. Least he can do is not overheat your apartment. Good luck to you.
Re: Detroit, MI Steam Contractor
Detroit Rock City!! Is Gerry Gill far from there? Closer than I am.... Mad DogHe's near Cleveland. Might be a schlep from there to Detroit, but you never know unless you ask.
