Frequently Asked Questions

We often have customers call with many of the same questions. In this blog post, we will begin to list some of these. Of course, we can’t add them all at once since that would take a long, long time. Instead, we will will begin to list them as we can, and update them at least monthly. If you have a particular tip you would like help with, please email us and let us know. We will always add your suggestions first.

Sometimes black stuff comes out of my faucets when I run the water. It happens in different rooms and does not happen all the time. What would cause this?

There are several possible reasons for discolored water, but ultimately water testing will be critical in diagnosing the cause of the problem. Minerals, including iron and magnesium, algae, pipe degradation and resin beads can all cause black water.

Magnesium is often found in water and when mixed with oxygen, turns black. If you look in your toilet tank and the inside is black, then you have magnesium and probably iron in the water. In either case, they are harmless to you. But if you want them gone, you will have to filter your water. Signature Plumbing can recommend a a water softener company to analyze your water and determine what you need to remove the color. If the piping in your house is steel or galvanized, you could be getting mineral flakes from exposed iron (rust). Under the right conditions, with the right natural minerals and elements in the water (like magnesium), then you could get black water out of the faucets. Natural resin beads from your water softener are often black in color, like charcoal. Sometimes the water softener can break down and the resin beads can get our and into the water system. Signature Plumbing in Plano can help you properly diagnose the problem and offer some solutions.

After putting in a new shower valve (diverter), why does the faucet still run water when the shower is running?

If you get water out of a tub spout when the shower is running, then there is something wrong with the diverter. Most faucets use either a diverter or a third handle in the center of the faucet to change the direction of the water up to the shower head. Diverter tub spouts use a disk that closes off the opening of the tub spout and forces the water up to the shower head. Some faucets use a push button in the handle assembly to divert the water up to the shower head. Finally other faucets use a separate handle inside the faucet body which changes the flow direction.

To fix your leaking faucet, disassemble the diverter and flush it out to make sure there isn’t debris blocking the closing of the disk, handle or button. Shut off the water to the faucet if you are going to work on the faucet body for the handle diverters or the push button diverter, or simply remove a tub spout diverter and replace it or clean it. If it is calcium and mineral deposits, soak the parts in vinegar overnight then clean with a soft brush to remove the buildup. Of course, the easiest way to fix this is to call us.
