Desolv™ | Mini-split Evaporator Coil Cleaning Kit

Rinse the coil, and all other surfaces which were sprayed, with water until all of the Desolv product has been removed.
Note: Desolv is self-rinsing from evaporator coil fins during condensate production of normal AC operation, but rinsing the coil fins with water should be performed after the application of Desolv to ensure the best results.

Q&A: U Bend, B Vent, Code Compliant?

Photo credit: TheDrPepper

Q: Only seen a couple of these around Chicago. Is this a code compliant exhaust cap? Was told it was because “rain kept blowing into the cap and dripping down the vent pipes.”

It is for natural gas furnaces (second floor) that connects to an upper units venting (3rd floor) and then out.

– TheDrPepper

A: Assuming it’s venting a category 1 appliance, no. At no point should a natural draft vent system slope downward. If the cap is leaking, get one that doesn’t. NFPA 54 section 12.7.2 -Gas Vent Termination – Tony3696

NFPA 54 section 12.7.2 -Gas Vent Termination
Page 229 has a pic of what is acceptable. It does not mention a U bend.  – 33445delray

SureSeal: Eliminate Sewer Gas and Evaporation

Using SureSeal Waterless Floor Drain Trap seals to Eliminate Sewer Gas and Evaporation

by Rick Ensley, SureSeal product manager, RectorSeal Corp.

Sewer gas rising from floor drains might be an unhealthy nuisance for commercial building owners and homeowners, but for plumbing service contractors, it should be a breath of fresh air for aftermarket and service call add-on sales that increase profits.

The common cause of sewer odors in floor drains is the evaporation of the gas-blocking water trap seal that prevents sewer gas egress through a floor drain P-trap. It’s especially common with infrequently used drains. Once evaporated, the trap seal is broken leaving nothing to block a steady supply of unfettered sewer gas rising up into the occupant’s breathing zones. Sewer gas is suspected of carrying airborne biological contaminants that can lead to SARS (Coronavirus), Legionnaire’s and other diseases.

Plumbing service contractors have four alternative remedies to this problem and not all of them are foolproof:

Homemade Air Heater – Will This Work?

Help!!! [Don’t want to burn the house down.]

Q: Hi all very simply it’s copper tubes, small pc fans, and surrounding the copper tubes is several 15 to 20w quartz halogen (I think?) heater spotlight lamp bulbs. If this is placed in a wall to heat a small bathroom bringing cold air outside in, will it be able to do so? Thanks a bunch – any recommendations for efficiency or a similar design welcome. – A1d4n_18

A: Sounds pretty good to burn your house down. How is this cheaper than something UL approved?

You’ll also not be anywhere near the same efficiency as something off the shelf. Don’t do it.

This. Pick up a wall can at the local big box home improvement warehouse for $100-200. It’ll not be a fire hazard AND it recycles warm air from the room, not cold outside air.
