"Installers arrived on time and worked very hard and efficiently. Project took two days since in addition to the shower conversion they also installed a new LVP floor and a new toilet. Rafael and his assistant were top notch and left the house and work area clean even at the end of the first day. I highly recommend them if you are considering a project. They made an effort to minimize the time water was shutoff as well."

Affordable Plumbers FAQs, answered by experts

If your pipes are suddenly making loud noises, it could be due to any of the aforementioned issues. A water hammer is a common cause of this problem. Other potential causes include water pressure issues, loose pipes, air bubbles, and worn-out fixtures. Mineral buildup in the pipes can also cause loud noises. 

You can use a water gauge to check that water pressure, which should be between 40 and 60 PSI. If you don’t have a water gauge, you can also time how long your showerhead takes to fill up a 1-liter container. If it takes longer than 6 seconds, you’re dealing with a case of low water pressure.

Water heater pipes can freeze in one night if outdoor temperatures are cold enough. The lower the temperature, the quicker plumbing tends to freeze. If your pipes are well-insulated and you take proper preventative measures during the winter, your pipes should not freeze as rapidly as unprotected pipes might.

Homeowners insurance may cover shower pan leaks, but it depends on the type of coverage you’re looking for. Typically, home insurance policies cover sudden or accidental water damage, for example, if it comes from a busted pipe or malfunctioning appliance. Damage to a shower pan is usually gradual. A repair or replacement of your shower pan usually won’t be covered by your policy. If your shower pan leak causes water damage, chances are your standard policy—if it includes water damage—will cover the repair.

Yes, there are different size sink drains, but a 1 ½-inch-diameter drain is the most common modern drain size. However, some sink drains are 2 inches or 3 inches in diameter. A bathroom sink drain is 1 ¼ inches in diameter, and kitchen sink drainpipes are 1 ½ inches in diameter.
