Yes, the first switch in the circuit from the panel would be a three-way switch. The last switch in the circuit before the pump would also be a three-way switch. Then the other 10 switches would all be four-way switches.

Yes, you use 4-way switches. Here is an animation that shows how they work. You can have as many 4-way switches as you want, in the middle. http://users.wfu.edu/matthews/misc/switches/4WayAnimation.html Changing the switch causes the pump to change. If it was on, it will be off, or vice versa. The switch position will not tell the user whether it's on ...

This is commonly used in industrial controls: I've drawn it as a ladder diagram because I think it's easier to see the individual circuits and the interactions between them. You can translate from that to the actual wiring. I'm using a second relay contact to power the load so that the control circuit only has to handle the relay, which is almost ...

For that many locations, I'd strongly consider one of the types of switches intended for home automation applications. One switch would actually control the pump, and the others would signal that switch to turn on or off. Some of them offer battery operated remotes that can be used without any permanent wiring, or you can mount a switch in a normal ...

Honestly if you have a contractor talking about basement flooring in a basement were there is a fear of moisture I would fire him on the spot if he mentioned installing real wood floors. Even in a basement with no "water" problems the humidity levels can reek havoc on wood and warp it. I see a bad wood install in a basement a couple times a year. I can't ...

Check all the supply valves to ensure they are open. It is not uncommon for old valves (particularly gate valves) to break whilst operating, leaving you with a low or no-flow situation (sometimes called a "dropped wedge"). This would require you to replace the suspect valve. If you did a DIY install, were any of the valves particularly corroded or hard to ...

TL; DR: When the temperature is colder outside, your cold water is colder so you have to use more hot water for the same shower temperature. Facts: A shower head puts out 2.5 gallons per minute (GPM) (or close to it). To get the temperature you want, you have to mix hot and cold water. In the summer, the "cold" water temp is much warmer than it is in the ...

You need an adapter that will transition from your tap's thread to a compression thread. Most (U.S.) refrigerators are equipped with 1/4" O.D. tubing which utilize 1/4" compression fittings. Your picture seems to show something larger than 1/4" O.D., my first guess would be 3/8" but if you are not in the U.S. I guess it could even be a metric size. As for ...

Most water heaters upon initial start-up can take several hours to heat the tank water to the setting on the thermostat. Also, if the setting is not at the hottest temperature and it is a large tank 12 hours isn't unreasonable. You should also be aware that if the entire tank of hot water is consumed for say a long shower it will take the incoming water ...

The other answers hit the nail on the head--wood floors in basements or anywhere subject to moisture is generally a bad idea. I just wanted to add one more vinyl floor variant that you should consider for a basement installation if you are already considering a click-lock floor. I highly recommend loose lay vinyl tile. It is similar to click-lock vinyl ...

I have gone through this too. If it sinking black particles then that is charcoal/carbon. That is from your filter. You can drink/digest it just fine but if that makes you squirmy then take the filter back. Honestly there seems to be something a little off about your filter but at the same time the particles aren't necessarily harmful.

If the valve handle is any indication for what its' function may be, than there is a very likely chance that it is a shut-off valve for: A. water supply (for flat above?) or B. sprinkler system (not likely). The valve type is either a "gate" or a "globe". Either of them are designed to control water (liquid or vapor) flow. Additionally both valve's have a ...

Lead isn't soluble in water (although some lead containing compounds are), so most filtration smaller than ~1 micron is typically quite effective at removing lead. Just look for a filter with a NSF/ANSI Standard 53 rating - it needs a 99% lead reduction to certify (link leads to a specific filter, but does list the qualifying criteria). Other contaminants ...

From the efflorescence on the walls, I'd bet there's slow steady seepage through the blocks and the mortar. The only solution for this would be an external entrenching and wrap. Also:

Call your gas supplier. ( I'm assuming you have gas piped to you house, and not using propane tanks.) As I found out when I moved from a flat region to one with hills, the gas company comes around a few times a year to check the pressure in the line. It could be your pressure needs adjusting. I also like the negative pressure answer. As an aside, I ...

A healthy home pulls in air, circulates it, and releases it. You have negative pressure when you are releasing more air than you are pulling in. This could be caused by a blocked intake or an over-working exhaust system. The most common, for a stove, would be a vent hood pulling too much air from your home than it can pull in to keep the fire going (see ...

Sadly not much. 100W would not effectively heat a 40 gallon water heater, let alone an 80 gallon. Also, remember that the panel likely won't really put off 100W unless your element has the exact right resistance for your specific panel. You can do some simple calculations if you're curious how much heat that will produce... If you use 100 Watts for 4 ...

I built my house in 1990 and to date there's never been any issuses with my septic tank and no pumping it. I don't believe in the ads saying it should be pumped every five years since it just takes away all the good stuf then you need to build up a new food supply and the proper amount of bacteria all over again and I have 2 baths a day since my car accident ...
