Word of advice. If you're not going to use the secondary outlet on the coil/air handler drain pan, add a male adapter with an elbow that will drian into the secondary pan. My first option in an attic is a mechanical float switch on the secondary outlet. I like the tradepro tp-cs-2. This way there is absolutly no question of water ever getting on the ceiling. Also a bonus is that you are not flooding the coil case/air handler case everytime the drain stops up. With a plug you run the risk of seeping water into the supply or return plenum if its flush mounted with the unit or coil, insulation gets soaked and drips on the sheetrock. From experience.
I can say this much, you can have, pans, multiple independent drains and float switches and still end up with water on the ceiling. people simply do not maintain their junk, until it's all failed completely or they/friend will go monkeying around and bypass everything. short of making it blow a hidden fuse and not run again until serviced, is about the only way, but they may still cobble it! don't ask, after doing construction/remodeling and work for slumlords(boooo), the renters don't want to call for problems either, because they trash the places or have drugs and partying all over the place.
Ted is a trooper to go into those crawl spaces. Dust is flying around and Ted is doing a belly crawl. Take care Ted that spring chicken stuff is for the birds. 😃
That R22 is from a Chinese company called QuZhou Bingcool Refrigerant Manufacturing. Its a legit company although you'd need to buy several pallets, like 5 or more and it would likely be confiscated by customs if shipped into the USA. To the best of my knowledge, most of the Chinese R22 is shipped into Mexico and then brought into the USA in smaller lots. There's many who do this then sell the product out the back of a van here.
I am a commercial/industrial HVAC/R tech from Toronto Ontario Canada, just retired UA member. I really enjoy watching your videos and see all the acrobatic shit you guys go through. Luckily for us, most of our residential systems reside in a full basement with condensate drains close to the furnace. Hoping one day we can connect when driving thru your state on my way to Florida. Kudos to you and all of what you do!
It seems if we can go to the moon with 1960’s technology and we now have the Dick Tracy phone watch, somebody could invent an ac drain that does not clog and a run cap that lasts the lifetime of the product.
That was quite a mess Theodore . Who would install an over flow with a drain to nowhere and put an over flow switch and not hook it up. Brain dead fools some of the installers out there. Nice work Theodore .👍👍🇨🇦
Hi like to have a safety switch right in the drain line so that way the system will shut down as soon as the drain line plugs instead of overflowing the internal pan and filling the secondary pan. The safety switch also gives you a convenient place to brush and swoosh out the trap and drain. Only having a switch in the secondary pan is like having a smoke alarm that tells you after your house has already burned down.
I hate working in crawl spaces you just never know what's going to be down there. And hey Ted this is Rick from Texas that issue I talked to you about on the phone turned out to be the TXV is bad. Low vapor line pressure high liquid line pressure. So I'm going to pump it down and replace the TXV.
looked to me like all "B" vent, including the double wall "B" vent flexible connector. granted some inspectors/locales may not allow them or throw a fit because they don't know about them. while they do make single wall and double wall flex connectors, the double wall is easily denoted by the labeling(if visible) if not, you can tell by the diameter increase at the flex ends, they step up a size to accommodate the the larger secondary outer flex pipe and then diameter steps back down at the b-vent connector ends. 🙂 hope this helps.
there's always too many variable involved. dirty coils, improper airflow, leaking ducts, large temperature difference(unit in hot attic) when it comes to checking equalized static pressures.
wait, a few angle it almost looked like they used the evap. pan secondary drain port, instead of the primary?!?! maybe optical illusion by the camera angle. lol
Interesting.... Questions: 1. How do you know this? and 2. Is there any way to actually get this price or some derivative of it as a US customer? Also, I have heard that in Mexico or some central or south American countries you can buy small quantities of R22 for something like 1-2$ per pound, but you cannot openly bring it in.
Gunna be an itchy ride home. Hate dealing with insulation. Unfortunately it’s part of the job. Doesn’t make sense why they ran all that line essentially to nowhere. They should of just ran the SS2 on the secondary and capped the emergency with a float switch. Usually what we do but you can’t always get what you want
Don’t know if your company installed them but I’ve seen wet switches installed in the auxiliary drain pan to prevent these issues they seem like a good idea for your customer
you can often buy any refrigerant online(without license certificate), as long as you sign a waiver, stating you wont use it/for resale and only a qualified tech will use it. I sure wouldn't buy large quantities, because that may get you a red flag visit of high cost fine(huge)
those all have draft inducers, so as long as the piping is connected the right direction and no obstruction, slight pitched horizontal exit is fine, before becoming greater pitch or going vertical. obviously don't point it out the bottom (vertical down) that's a no-no and no horizontal on models without draft inducer(although that wasn't uncommon long ago)
