    After 45 years of faithful service we finally had to replace our submersible pump. This is a 10HP unit, 300 ft down in a 6 inch casing, serving 4 households. The water level is 60 feet above the pump, which is the same as it was 45 years ago. The water is pumped up to 2 5,000 gallon tanks, which...

    I took the front panel off of my AC air handler looking for a common wire for a smart thermostat. When I took the panel off, I found a couple of wires have what I think is dried mold on it, but I'm not sure. Does anybody know what else it could be? These wires are above the coil. Whatever it is...

    THANK YOU in advance for looking at this thread & forgive my ignorance- Recently here in Missouri, we have had several weeks of teens to sub degree temperatures. My Bryant Plus 90 Furnace has started going through the "pre" cycle but then dies out with what appears through research to be a...

    I have a Rennai tankless water heater. The pipe-in-pipe dual exhaust pipe runs through a conditioned crawlspace, then outside through an exterior wall. The outside temperature is currently 26 degrees Farhenheit with 25% humidity. The inside temperature is ~74 degrees, and 43% humidity. I've...

    As far as CFM's required. I understand that it's the cf. of the room times a minimum of 4 divided by 60 for the formula. My room is 1206 cf. so according to the formula; air circulated 4x per hour = 80 CFM air circulated 6x per hour = 120 CFM All of the equipment will be in the room and it...

    I'm new to the forum and to DIY / home improvement in general, so please forgive any misusage in rules or terminology. Hi everyone. I moved into a nice house (renting) recently, but one thats very old (1960's). Some of the windowsills and floors let outside air through and it makes it...

    Can flex duct be used in place of a normal return plenum? I've read it can so long as it is not the only return in the house but not sure how good the source was. 8" is probably the biggest I can use but the plenum takes up 2 joist cavities, so run 2 flex ducts? Thank you.

    Hello, I recently had some vinyl asbestos tile removed from my basement. The baseboards has to be taken off, and the drywall is sometimes resting directly on the floor, and sometimes it's a half inch off the floor. I had an air quality testing company in for a separate issue, but while they...

    I've been diligently sealing up air leaks in the A/C duct work in our unfinished basement, using high quality heavy duty foil tape. I've sealed up everything I can get to. What I've now noticed is that most of the remaining leaking air is coming from the damper controls (I guess that's what...

    I have a bladder-less tank (Amtrol RT42TT) with a Braukmann Auotomatic airvent. There are 1-1/4" fittings at the bottom. It is a submersible pump with a check valve. The system has started short cycling and I have inspected all fittings and tested the tank and there are no leaks. My dilemma...

    Installing a standard 60X32 3 wall rectangular air jet tub and was considering a wall mount faucet with hand held shower nozzle like the ones used for claw foot tubs. Is this too unusual a combination? I never see this on tubs but thought it would look nice. Is there a reason not to use this...

    1. I have an old farmhouse - just gable vents. I'm about to add more blown in cellulose to part of the attic - do I still need to use ventilation baffles in the soffit area even though there is not soffit ventilation? I have heard conflicting opinions on this. 2. Half of the attic has plywood...

    I have a duplex and had both of my tennants call me to say that the air conditioners are not blowing cold. They are completely separate. They are both split systems on seperate meters/panels. Both of the condensers? are on in the outside. The copper pipe that should be cold was not. I had a...

    I am having a problem where the standard 9.5" duct air deflectors do not fit my 9.25" ductwork. My house was built in the late 50's and has the square metal ducts. Is there any better solution besides trimming back the ductwork and taping it to the wall so that a new deflector can fit? I can't...

    I just got a new Trane system installed last year thinking it would help but it has made no difference. I have gone back and forth trying to figure out why my house will not stay at a comfortable temp in the extreme summer/winter months. I have an old brick home with what I assume has no...

    My bathroom sink won't drain UNLESS I close the drain while I start the water running. When the sink is almost full of water, I open the drain, I hear an air pocket dislodge, and then the sink drains just fine-- quickly, smoothly, no gurgling -- it drains fine AFTER I first close the drain...

    Hello, I need to take a cold air return in the basement to the floor level. One of the options I was considering is to cut the top plate as shown on the image (stud on the left is missing) and cover the space between the joists with sheet metal for the upper part. For the vertical part of the...

    After five years living in my house the kitchen hot water pipe now vibrates when turned on. I need to turn the water on very high to avoid any vibration. The bathroom hot water does not. House was built in 1940. Previous owner had new copper plumbing put in ten years ago , or so. Except the last...

    Looking for the best air compressor for light-duty, DIY-friendly use. Probably going to use it max once or twice a week. Fill tires, maybe run a nail gun or stapler. Might also use it to blow out auto parts or electric woodworking tools. Price isn't necessarily an option, but I don't really...
