Is it safe to fully remove the PVC and try sucking from there? And that red rubber cap, what is behind it and does it have anything to do with drainage?

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...

Hi guys I bought a foreclosure here in forest va. The pipes were winterized. On turning on the pumps and letting water into the house... everything seemed fine. But since mo've in I have been experiencing air in the water lines. Every morning I wake up and there is air in the lines. Air seems...

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...
