Plumbing, Heating & Air Conditioning FAQ

Providing Services in the East Valley

It’s always best to have a licensed, certified air conditioning technician or plumber, such as the ones at Frederick & Sons LLC, have a look at your A/C or plumbing needs to be sure any issues are correctly identified and fixed. That said, below are some questions that we’ve heard time and time again and we hope the answers will be helpful to you in getting an idea of what you’re looking at.
  • My toilet slowly overflows from the flush handle opening overnight, but during the day and evening this does not happen. What can I do?

    Take some blue food coloring and put it in the toilet tank until the water turns blue. If the color of the water in the bowl turns blue, then your flapper may be leaking. If you do not see any blue coloring in the bowl, then the water may be running into the overflow tube in the center of the toilet from the fill valve.

    Try to shut the water off and then remove the ¼ inch tube from the center fill tube to see if the water continues to drip. If it does, then you may need to replace the fill valve.

  • The kitchen sink is causing a terrible smell into the house. Is this a clogged vent?
    It could be a clogged vent or a clogged drain, as either of these situations will produce the same condition that allows sewer gas to enter your home. Our team can fix this type of issue, which may be constantly by leaves or birds' nests and squirrels' stashes in the vent pipes. Have our team help you clear the vent and / or drain.
  • There's a sewer smell in the wall behind my bathroom sink. My home is on a slab and has no crawl space.

    This is a common problem in older homes, where the soil may settle under the concrete, eventually causing the piping to break off under the floor. The threaded joints can be weakened from corrosion or acid drain cleaners. Cracks in the concrete can cause the smells from the sewage to seep through.

  • How often should I have my drains cleaned?

    This depends on how often you put grease food products down the drain. To avoid kitchen plumbing hazards, do not pour grease down the drain. Always use a paper towel to wipe any grease from pots and pans before washing. The grease that is washed down the drains will coagulate and eventually clog the drain line.

    Using a garbage disposal also increases the need for sewer cleaning. When you use your garbage disposals, you deposit more sludge and debris into your pipes. It is better to discard your food into the garbage can. Avoid putting hard or fibrous food (such as celery, carrots, etc.) in the garbage disposal. Use enzyme drain cleaners to help lengthen the time between cleanings.

  • I have a slab house and my polybutylene water main is broken under my house.

    When a line breaks under your house, we will typically abandon the old pipe and determine the simplest path to get to the main shutoff valve. This may involve rerouting the pipe through a utility room or a short directional bore under the slab. In some cases, we can move the shutoff valve and regulator to a different location, which saves rerouting work.

  • My toilet sounds as though it flushed itself.

    When the toilet douglas valve seal is warped, this causes water to leak out of the tank. The fill valve as a result senses that the toilet has been flushed and tries to refill the water tank level. This can cause enormous water waste, so call an experienced plumber for service immediately.

  • We have low water pressure – why?

    This can be affected by a number of reasons, such as the amount of water the utility is pumping out, the age of the pipes, and the amount of rust present. We can troubleshoot your issue and determine whether this is a water flow/pressure problem and the causes.

  • Should I drain my water heater annually?

    It is not necessary, but doing so won’t hurt. However, the best way to protect your water heater is by changing the ANODE ROD. This rod runs down the center of all heaters and should be changed between 2 to 4 years, depending on how rough your water is. Have a qualified plumber maintain your heater to avoid costly fixes in the future.

  • My water heater isn't working as well as it did before. Why is this the case?

    Chances are good your water heater may be failing due to sediment buildup in its tank. Over time, your unit can accumulate debris like sediments and lime deposits, which must be removed periodically. If not regularly flushed, this sediment can form a barrier between the water and the burner, reducing your unit's performance and requiring more fuel to heat up the water.

  • Can I replace a two-handle faucet with a single-handle faucet?

    In general, yes. Most faucet dimensions and sink openings are standardized, but it is still a good idea to double check the sizes first.

  • My toilet is sweating and dripping water on the floor. What can I do?

    The water on the toilet tank is condensation, which is caused by cold water in the tank continually drawing moisture from the warm bathroom air. If you want to stop this, you can purchase a kit that allows you to mix some warm water with the water going into the toilet tank.

  • My central AC unit is leaking water into my house. Is my pan rusted out?

    Most air conditioners have plastic pans. The leak could be caused by a clogged-up condensate line.

  • My condenser on the ground is getting frost on the pipe hooked to it.

    To start, change the filter and let it run to see if this helps. Set up an appointment with our team to have the system looked at.

  • My digital thermostat does not display numbers on the screen.

    If your thermostat is battery-powered, replace the batteries first. If it isn’t, check your circuit breakers to see if any are tripped. Reset the tripped breaker. If you are unable to resolve the issue, contact our team for a diagnosis.

  • When I have my thermostat in cooling mode, my HVAC system blows warm air at first? Is this normal?

    Yes. In general, the attic is very hot so it may take a moment to circulate the air and for the evaporator coil to get cold.

  • I have two pipes sticking out the side of my house. One always drips but now it doesn’t while the other one is.

    There could be an issue with the low condensate line or the pan may be clogged. Call a professional to have it unclogged if you can’t do it yourself.

  • What type of saw should I use to cut a hole in the ceiling to install a bathroom vent fan? Can I just vent it into the attic without having to put it through the roof?

    We do not recommend that you vent it to the attic. Over time, this will cause moisture to build up and cause damage to your roof and insulation. If you live in an area where it gets cold, this moisture will condense during cold weather and rain. Instead, we recommend you vent it to the side and out to an eave vent.
