I’ve read this note RC Low-pass Filter Design (Sample) to design a a low pass filter for converting 120 VAC to 0-5V to input as analog into the arduino. Attached is the filter I’ve got on the bread board now and it isn’t working and I can’t come up with where I’ve went wrong. The voltage...

Our dishwasher was filling up and while cleaning the filters, my partner took out the Wash-Cycle Pump Protector and cannot get it back on. After looking at the instructions, in bold letters it says do not remove. Does this mean it is broken beyond repair?

I realize this is pretty specialized, but if you're landscaping, maybe you're also dealing with ponds and their filter issues. It's clear I need at least a new impeller (replacement part pictured), but I'm debating whether it's time to buy a whole new Laguna 960 filter pump. I plug it in and...

I just bought a home that has well and septic and everything seems to be fine, but I like knowing my hardware. I have installed RO filters in the past under sinks but a well water system is a bit out of my current league (not that I cannot learn). I wanted to share some photos and need help...

Not sure this is the proper forum...couldn't find a better one. Maybe 50 years back I recall reading a story about a canoe with a small egg-beater motor getting stranded out on a lake with bad weather approaching, the problem was water in the gas. One of the canoeists poured the gas through a...

I need help removing water from an air compressor line so I can spray paint without issues. I am a total newbie. I have sprayed polyurethane before with really great results (it was about 13 years ago when I built a baby crib for my daughter and the sprayed on polyurethane top coat turned out...

Is there a water filter (e.g., an under-sink filter) so I could safely drink hot water from the tap? I was warned about sediments, and that this is not a good idea. But with a filter that can work with hot water, I think this would be possible.

We had a water system installed several years ago, and it did a great job. However, the iron problem we had is back. This is an Iron Boss that supposedly had much capacity to spare. I've used Iron Out and backwashed it repeatedly, but it seems it's worn out. It's been serviced, and the tech...

Hello, I just moved into a home that has a TRANE XE 78 in the garage, and I can't figure out how to change the filter. The side panel says it was installed in 2002. I reached up inside as you can see and pulled out 2 of these metallic looking filters, but they were just sort of propped up in...

Hello, I've got a problem with what I think is inductance from mains cable into the speaker cable. When I short the speaker cables with everything off I'm getting a pop through the speakers. When I ran the cables I tried to keep them separate but I obviously didn't leave enough room. I don't...

We just got our new home and it has a Heil furnace. The model is #N8MSN0701412A2 and we are unable to locate the Air Filter. It seems like it was installed upside down and there is no filter location on either side of the furnace itself. I am attaching pictures in the hopes that someone may be...

Hi Everyone. Narrowed down a spider problem to a 3 inch pipe that's beneath (yes) the big elbow that brings the cold air return to the filter housing, to the furnace. I've seen 4 inch filters strongly recommended on numerous occasions in these forums, and since I have to take the elbow off to...

Left last night everything was fine...came home this morning and house was cold...checked thermostat and realized filter may be clogged...I'm terrible at maintaining this.... Sure enough ...took out filter but didnt have a replacement....now furnace is kicking on and off every few minutes...

Hi guys. I would love some help in designing a filter to help prevent sewage clogs in my pipe leading to the main line. I live in a house on a college campus that is over 100 years old. Our sewage line constantly (averaging around twice every three weeks) clogs during the home stretch before...

Can somebody tell me the best way to fix air leaks in furnace duct lines, i know of 2 ways foil tape and spray stuff, does the spray stuff work and where can i get it in Canada.:whistling2:

Good Afternoon- Our previous furnace was installed weird and had no filter. It is up in our attic. Last year we spent some serious coin and got a new one. I assumed someone else who was here when it was installed knew where the filter was, and had been changing it. The company we purchased it...

I have a one of those Intex pools that go up for the summer, and are taken down (If i get to it) in the fall. Power is 150ft away at a GFCI outlet on our front porch. That is the only outlet around the exterior. I have an extension cord running to the pool, but am wondering how I can turn it on...

Hello all, I just changed the filters in my A/C units (last change was 3 months ago) and found that one was dirty and the other was clean. Both units were installed in the attic at the same time. The unit with the clean filter services the downstairs of our house, and the unit with the dirty...

Hello all, We have a two cell electronic air cleaner on our furnace that has taken to "snapping" incessantly. This used to mean a bit of fluff or something was lodged in there, but they are clean. The ducts have been professionally cleaned and the metal pre-filter is clean too. I noticed...
