Doing a rehab with new HVAC (attic space) and tankless WH. We have an HVAC (3/4") and WH (1/2") condensate lines we need to exit into a 1-1/2" line (already) plumbed into the utility room. (the house is slab on grade) What are the requirements (if any), other than a trap attached to the...

Doing a kitchen addition for a rehab and the main waste line is running right through the new crawl space. Was planning on replacing the cast iron inside but this would also give us the opportunity to (at least partially) tie in and add a cleanout to the line exiting the house. (line exits...

Should there be?

Don't do much sewer line work so excuse my ignorance :O)! Working in a township that requires a sewer lateral scope. Did the scope and the lateral out to the main is fine, but they called out the (attached photo of the) clean out, saying the slotted lid does not meet code and they needed to...

Anyone have troubleshooting expiernece with this boiler? Pilot will not stay lit. (GVD-5) vent damper is vibrating and does not appear to be actuating but I can't find any trouble shooting info to bypass and confirm it is the damper. Open for suggestions...

Thinking about installing a whole house generator and wife has been saying she wants a pool (for the last 15 years) so I figured I'd be proactive and confirm my (gas) service is adequate. Call local Util, who sends me a form to fill out with total BTU requirements, current & proposed. Fill it...

Little get-away to Asheville NC and visited the Biltmore Estate House (Vanderbilt). Think it was finished in 1898 (don't quote me). Supposedly had hot/cold running water in all of the 43 bathrooms. Managed to snap a pic of this very cool trap on one of the changing room sinks! (not sure it's...

Any recommendations for (an easy to use) ISO drawing app or program? Project: 1.5 story Cape, complete gut inside - starting from scratch, 2 baths (1 up, 1 down),1 half (down), laundry (up), kitchen. Going to need to move main line to have it line up with new walls. (PS. also not opposed to...

Question from a buddy I couldn't answer... Said his 1st floor has (under floor - never saw it so I'm not sure of the type/system) radiant heat supplied by a 75 gallon gas fire tank that (he says) also supplies hot water for the home. He's asking if he could switch over to a "tankless" version...

Local Lowes stores have all of their EvoPex on clearance right now. Comparing to SupplyHouse and Lowes is 40%-50% less (marked as clearance!?)

Anyone know if a Wilkins (Zurn) 700 regulator is adjustable? Installed a whole house filter and water softener, pressure started out at 65 psi (at furthest point hose bib) and is now at 37psi. (regulator pics attached)

Getting ready to install a whole house filter & water softener. Water meter sits inside a 3'W x 6'D closet with a grinder pump right in the middle. The softener could be placed right in front of the pump and would have enough room to service but if I ever needed to get to the pump I'd be SOL...

Recommendations for one you know, like & trust? (considering upgrading from the Oatey leak detector bottle)

From what I've learned (here), the trap arm needs to be 1.5x the (largest??) trap diameter. If the tail pipe (1.25") piece dumps into a 1.5" p-trap, the trap arm would need to be at "least" 3", beginning at the trap weir? Question is, does that 3" need to be exposed? (in other words;) if the...

Judging from @matt.mena 😎 last post this may be his question! 50's era Cape - total gut and rehab. Slab on grade, water, soil and (heating) ducts under slab. Looking to do some reconfiguration to bring up to 2020's standards. Need to move main stack/soil & water and WC about 12" into the...

Anything, other than condensation, causing this?

Trying to learn from the more experienced (and much older :O)) pros here... Came across this one last week on an inspection. (the vertical pipe goes up into an AAV). Is this legit or is the trap arm too short? How to fix?

(post #2 for the day :O)) Anyone have a recommendation for a garage/shop heater, preferably electric? 20 x 20 (400 sq ft.) Just need to keep the edge off in the winter (in the Philly area). Have a 240v run but not gas. Love to be able to have it thermostat regulated.

Didn't want to step on the OP toes for the other thread going on but had (what is probably a stupid) question... (also) looking into a whole house generator and wondering why you "would not" run the largest line possible? Example: my meter (250 CFH) is fed by 3/4" (no pressure rating on the...

Probably moot but open for suggestions. Working a rehab - these are Levittown (mass built specs) type homes built on-slab and the original laundry drain line is 1" copper. Thoughts on a solution or just leave it?
