Frequently Asked Questions
Everything you need to know, all in one place.
I need basic plumbing repairs in my home to fix a leaky faucet or clear a clogged drain. Does Williams Plumbing handle these types of issues?
Yes! At Williams Plumbing, our highly skilled plumbers will install and make repairs to pipes and plumbing related fixtures, diagnose clogged drain problems and solves all other problems that may be related to the water systems in your home.
I want a new sink or faucet in my home. Should I try to do it myself?
Many homeowners are very capable of handling these kinds of jobs by themselves. Some home centers even show you how to do so. However, through our past experiences, we have found that some projects are better left to the professionals. Williams plumbing professionals provide quality installation and upgrades of sinks, toilets, laundry tubs, laundry hook ups, bathtubs, whirlpool tubs, showers, all kinds of faucets, garbage disposals, and much more.
How do I un-jam my garbage disposal?
You may be able to insert an Allen wrench into the bottom of the disposer and “crank” it to help free up a jam. If this doesn’t work, DO NOT USE YOUR DISPOSAL! You could cause serious damage to the disposal motor or even the electrical system of your house. A professional from Williams Plumbing can usually fix a jammed up garbage disposal. Our expert technicians can give you the best advice and make quick work of it to get you going again.
How do I know if I have a broken water line outside my house?
A broken water line out in the yard may lead to an excessively high water bill as well as puddles in your yard or the sound of constant running water when no appliances or faucets are in use. The professional plumbing technicians at Williams Plumbing can “see” inside your pipes with Video Camera Drain Inspection technology. We can pinpoint the problem without needless trial and error destruction of working pipes. In many cases, we can fix the problem right away and save you money.
What is the most common reason for sump pump failure?
The most common cause for sump pump failure is a switching problem. The pump can also move inside the basin from time to time causing the float that operates the switch to lodge against the pump’s side. Debris can also be a major factor by interfering with the action of the pump switch. It is important to make sure that your pump switch and float arm assembly are able to move freely. A professional from Williams Plumbing can test, maintain or replace any brand of sump pump quickly and at low cost to you.
If I need rooter service, should I call one of those national rooter chains?
We would recommend that you call a qualified, trained and certified plumber. Why? The water pipes inside and outside your home can be very delicate. In older homes, pipes wear thin from the inside out making them appear sound when, in fact, they are very brittle. An unqualified and unskilled rooter company could cause extensive damage to your pipes and your home. The highly trained and certified technicians of a professional plumbing company like Williams Plumbing will take the time to properly diagnose the situation and utilize the right tools and techniques to solve the problem. Should there be an issue of a broken pipe or other unforeseen problems after we begin the job, our expert plumbers can immediately take action.
What causes low water pressure and what can I do about it?
There are several different factors that can cause low water pressure, including a partially closed or malfunctioning shut off valve, a crimped water line, or even deposits that gather in older galvanized pipes. If your neighbors have strong water pressure and your house does not, the problem is most likely between the water meter and your home. A professional plumbing technician from Williams Plumbing will be able to identify the problem and explain your options to get the water pressure back to where you like it.
Is there really a difference between hard water and soft?
Yes, and the difference can be damaging to your home and your body. You may have experienced damaged clothing from the laundry, excessive soap consumption, pipe scaling, faucet and fixture deterioration, skin problems, or undesirable tastes or odors from your water. If you have any of these problems, then you may have an issue. A professional from Williams Plumbing can solve your hard water problems with a variety of quality products for your home.
Should I install a conventional or tankless water heater?
There are many things to consider when choosing between a conventional or tankless water heating system. Williams Plumbing can guide you through your options and get the right system for home that will give you years of service and efficient performance. Conventional water heaters are by far the most common type of water heater in the U.S. today. They range in size from 20 to 80 gallons (or larger) and are fueled by electricity, natural gas, propane, or oil. Called ‘storage’ units, these water heaters transfer heat from a burner or coil to water in an insulated tank. The down side to a conventional water heater is that energy is consumed even when no hot water is being used. Tankless water heaters do not contain a storage tank like conventional water heaters. A gas burner or electric element heats the water only when there is a demand for hot water.
What causes my faucet to drip?
When a faucet is dripping, the solution is relatively simple. The internal mechanism of the faucet needs to be rebuilt or replaced. This is an easy, quick and inexpensive fix that Williams Plumbing would be more than happy to assist you with.
How often should I have my heating system maintained?
Your heating and air conditioning equipment should be serviced at least once a year. The best scenario is to have a certified technician from Williams Plumbing check the heating system in the fall and the air conditioning system in the spring.
