Question:
Which is better, duct booster or more blower horsepower to get cooler air to the upper level of house?
Answer:
The duct booster will be better. Put the duct booster fan in the duct feeding the upstairs. Increasing the blower horsepower in the main unit will add more air flow to the house but, this will lose cooling efficiency and it means the unit will not work as well.
See my article on duct fans.

Question:
Is it possible to weld a galvanized steel pool that has several leaks, and if so, how much money would I be looking at if I had a welder come weld it?
Answer:
The cost will depend on: 1. Is the pool full of water; 2. Is the plastic liner still in it; and 3. How thick is the metal?
Welding on galvanized steel requires the user to be careful as the smoke that comes off the weld can be toxic.

Question:
I have a 1-1/2 HP self-priming centrifugal water pump for lawn sprinkling. A timer mounted in my garage can be set to operate it automatically or manually. When I manually switch the timer on, the front yard can be watered. After 1/2 hour I switch it off for a few seconds then back on again to water the back yard.
My question is: What kind of "zone valve" do I have that switches zones (front yard to back) simply by shutting off the pump momentarily and back on again? There are no wires attached to the valve housing which is located on the discharge pipe from the pump. I need to replace it, but I do not know what this type of valve is called to search for a replacement online.
Remember, there is a single valve. No switches or electrical connections to the valve. Changes in water pressure cause the valve to direct the water from one zone to the other. This is not a solenoid type valve.
End switches do not start the pump. An electrical switch starts and turns off the pump. The pump operates independently from the valve that directs the flow of water from the front to the back yard.
Answer:
You have a mechanical zone switch. Look for a round plastic device near the output of your pump with a pipe from your pump going in and two pipes coming out. What happens is when pressure from the pump is applied, the plastic plunger goes up and delivers water to zone one. When the pump turns off, the plastic plunger falls down and rotates 180 degrees. The next time the pump comes on, it delivers water to zone two. It is possible to have multiple zones with a key that is only activated for two zones. If you find empty pipes this is why.

Question:
Removing sticky glue. How do you take off a sticky substance (like the glue on those mouse traps) from an electrical cord plug (like an iron)?
Answer:
Wipe off excess by using a towel. Try to keep it off of your hands. It is not good for you. Rub with vegetable oil or baby oil first. If that doesn’t work, rub with paint thinner.

Question:
When installing a dryer vent hose, I am aware that only metal hoses should be used. However, I have also run into a lot of dryers installed with metal hoses but plastic clamps securing the hose to the dryer and the house - Is a plastic clamp appropriate?
Answer:
The best option is to use metal claimps. The best one's are the worm drive stainless steel model. Just remember you are not crushing the hoses. Use just enough tension to keep them from pulling apart. Plastic clamps will not catch on fire or melt, but they have a tendency to stretch in time and allow the joints to separate.

Question:
Can I refinish a bathtub? I am renting a 1930s house and do not want to buy a new bathtub but the original finish (I believe porcelain) is now very rough and stained.
Answer:
Bath tub refinishing is not a chore for amateurs. We have attempted several with mixed results. The local big boxes all sell kits that promise to give you a new finish. The problems are many. Prep work is mandatory as all the surfaces MUST be smooth, free of any chemicals (soap & oil), have no large scratches or gouges and no chips missing in the porcelain. Also, working with the required chemicals in the confined space of the bathroom is not good for your health.
If you decide to continue on, do not use a brush to put on the new finish. Brush marks always show up. Instead use a paint sprayer to put on the new finish. Then allow several days for the finish to dry. The longer the drying time, the smoother the final finish. The problem is, however, with the long drying time this allows for any airborne particles to collect in the finish.
Here are several other options for you to consider. Several companies will "wrap" the tub with a vinyl cover unless your tub is a claw foot or some exotic form of tub. If it is a claw foot tub, it can be easily removed and you can then take it to a shop that can do this work in a clean environment. They can bake the finish and have it back to you in several days looking brand new. The other option is the replace the tub. New tubs can range from $65.00 up. The real cost is not the tub, but the walls surrounding the tub. Bring in a tub contractor and get some opinions. Maybe the landlord will pay for it if he/she thinks you will stay longer.
