    Hole in Basement Floor

    I missed the part about your feet. Scratch what I said before. The hole should not be filled in and should not have hard to lift floor coverings over it. While it would be nice if water spilled elsewhere on the floor gravitated towards the hole, it is not necessary or desirable to skim coat...

    Hole in Basement Floor

    Are you sure you do not have ground water or storm water leaking or seeping into the basement? Pour water on the floor in many different places (including next to the water heater and next to the washing machine) to see if every puddle gravitates towards the hole. Then you can see if the hole...

    water line under footings

    In order to lay the pipe you would have to disturb the land up against the pipe. Have a few inches of fine sand on all 4 sides of the pipe, well tamped, together with tamping any disturbed ground nearby that the foundation will rest on, and the pipe should be fine. Then, should the foundation...

    Can't get garage door closed tightly

    If you get rid of the tendency of the door to rise again an inch after being pushed all the way down then the opener will need to exert more force during the opening cycle. I am guessing that the overall power consumption in the long run will become greater.

    Don't look now but pure lithium (a metal) reacts with water to give off hydrogen gas and heat.

    Porperty Lines question

    You will want to find out the property line because it is possible the old fence is not positioned correctly. If you go ahead and build the new fence and no one objects then the new fence might become the property line after so many years due to adverse possession (squatters' rights). You might...

    OK to use highest rated filter?

    I unscientifically suggest: If the store has 3 grades of the same filter brand, choose the lowest. If 4 grades, choose the second lowest.

    Bonded Ground and Neutal in Outbuilding Panel

    The old feed would not have to be disconnected assuming it (without an equipment grounding conductor) was legal when it was installed. (It was much more than 6 years ago when ungrounded feeds were outlawed.) Except if you need more amperage you would have to decommission the old feed when...

    Is it recommended to connect french drain to downspouts?

    Water must not pool up around the foundation. It is usually not a good idea for water to go down into a hole close to the foundation. But if water did go down such a hole and never overflowed and never seeped into the basement then you are okay for now. Small amounts of wetness where the...

    Draining pressure tank

    A pressure tank with a bladder must have an air inlet valve somewhere, usually at the opposite end from the water pipe connection. Possibly covered with a screw on plastic cap or escutcheon or trim piece. During normal system operation, several gallons of water go into and then out of the...

    Grading the yard and installing French Drain. DIY?

    You need to regrade the land gently away from the house as far as possible, then if absolutely necessary slope up more sharply to meet the original level near the lot line. I do not think you need or want any French drains, except slightly below basement floor level around the foundation...

    Wiring Problem

    If you mix wire gauges then the breaker for the entire branch circuit has to go with the smallest gauge wire, for example mixing 12 and 14 gauge the maximum breaker rating is 15 amps. Sometimes using a larger wire gauge than the intended or required breaker rating is necessary, for example a...

    Leveled toilet now leaking

    Make all of the adjustments and put all needed shims in place (glue preferred) and do a test fit of the toilet without the wax ring. The toilet bottom must not touch the floor flange and the toilet must not rock during the test fit.

    To bond or not to bond, that is the question...

    Under the most recent code (actually for several decades now) the first disconnect location, which may be under the meter, is the "main panel" and separate ground and neutral must continue from there to everything including to a large basement panel you may have referred to as the "main panel"...

    ground wire

    All ground wires entering a box must be connected together there. This may or may not result in a circular ground path, say, leaving the panel, going through several outlet boxes, and returning to the panel via another route. Use additional short lengths of wire (as pigtails) if needed to also...

    So, I bought a house....

    Suggest having the septic tank pumped out, first thing. Best if the person you hire knows about septic systems because there may be a need to repair or replace baffles in the tank at the inlet and outlet. Two to three years between pumpings is a good starting point. By the third pumping the...

    Split large magnet into smaller pieces

    The copper coil is not needed to use the magnet as a magnet. The copper coil is used to make a loudspeaker out of the magnet (and other components).

    Split large magnet into smaller pieces

    Dropping a magnet on a hard surface, or hitting it, can weaken its magnetism.

    How can remove rust from this meat grinder in a food-safe way?

    Bake the disassembled parts (excluding the handle if wood) in the oven at about 300 degrees for at least a half hour and it will be sterilized free of tetanus and all those nasty germs associated with rusty objects. Caution: Give it time to cool down when done. The heavy metal parts will stay...

    Help Identifying a Bulb

    They make LED lamps with the smaller (candelabra-E12-C7 and intermediate-E17-C9) bases although not all permutations of different styles and color temperatures in all bulb shapes and base sizes. Caution: Some LED lamps have a plastic collar just above the metal base (like in the picture above)...
