Is it possible to prevent smoke coming into the house and how much would it cost?

Findingmorty asks:

My neighbors smoke like fiends and I’m having breathing difficulties. As best as I can tell, they smoke outside and it drifts up and into the attic via a permanent vent on the side of the attic. Then somehow it makes it’s way into my room and the ventilation system. The A/C unit is on top of the house and come summer it will suck it in as well and blow it all throughout the house. Is there anything an HVAC professional can do about this and how much would it cost?

Can this issue be fixed? Yes, Will it be expensive? Yes. Your house is allowing outdoor air, which is contaminated with things such as your neighbors smoke, because your home is under a negative pressure and/or extremely leaky. The first thing I would do is find a reputable HVAC contractor who specializes in indoor air quality. They can examine your homes envelope and HVAC duct system and other venting systems like bathroom and stove exhaust to try to determine exactly how the smoke is making it into your living space. From there they should be able to recommend steps that can be taken to correct the home envelope. Another benefit to hiring a professional such as this is that many of the repairs needed to solve problems such this also benefit you by preventing the outdoor heat from entering your space in the summer which in turn can dramatically lower your electric bill. A less expensive option may be to purchase either a duct mounted whole home PCO type of air purifier or a standalone one. You will need one that either has an ionizer or PCO (Photocatalytic Oxidation) technology. Keep in mind that ionization will produce ozone so for some people can cause issues, however it is very good at getting rid of cigarette smoke. I hope this helps.

How do I drain this water?

user Mr_Assault_08 asked:

Getting a new home and I noticed the water build up in the drain pan. It wasn’t here when they installed it, maybe after they tested the heater or something. But I’m worried the water here will eventually (years) damage the tank. So how do I drain it??

Answer: You could just sponge it out. At the big box hardware stores, they have sponges in the tile section that would work great.

Another alternative answer: Check your pressure relief valve. It’s probably blowing off. If it is, you’ll want to get a water pressure gauge and check your water pressure. If it’s above 85 psi you’ll want a water pressure regulator at your main and an expansion tank on the cold feed to the water heater. If you get this far make sure to brace the expansion tank so it doesn’t snap your water line and pump it up to match the pressure of your house. Hopefully it’s just a bad relief valve. Good luck bud

Is this installation legal?

User botlit asks if this photo of an installation is illegal or not? What do you think?

Answer: As long as the vent on the regulator meets the distance requirements to doors, windows, fresh air vents, sources of ignition, etc. it should be legal. Copper can be used as long as it’s flared – or sweated with material that has a melting point above 1,000°F.
