Frequently Asked Questions

Is it legal to work on the plumbing of my own house?

In Texas, homeowners are allowed to perform plumbing work on their own property without a license, as stated in Sec. 1301.051 of the Occupations Code. Simple plumbing tasks, such as changing showerheads, installing new toilets or dishwashers, and replacing washing machine hoses, can be safely handled without special training. However, complex projects like new water lines, leak repair, or bathroom renovations require a licensed plumber. Contact Radiant Plumbing and Air for expert assistance with any intricate plumbing repairs.

The cost varies, considering factors like distance from the main water source, chosen plumbing materials, number of fixtures, and local labor rates. Typically ranging from a few hundred to a few thousand dollars, specifics depend on factors such as plumbing material, fixture quantity, and permit requirements. For an accurate estimate, schedule a quote online and Radiant Plumbing and Air will come out to assess the cost for adding plumbing to your shed.

If you’re dealing with low water pressure in your home, particularly in an old house, start by checking for leaks, inspecting the pressure regulator, and cleaning faucet aerators to remove sediment. The age of pipes and the type of material (Galvanized pipe) may contribute to reduced flow due to corrosion and mineral deposits, so consider replacement. Ensure water shut-off valves are fully open, and if necessary, install a water pressure booster pump. If issues persist, reach out to Radiant Plumbing and Air. Our skilled technicians will diagnose the problem and recommend effective repairs tailored to your situation.

The duration of replacing a main water line varies based on factors such as the line’s length, soil type, terrain, and potential obstacles. Trenchless water line installations can often be completed in about a day or two, while traditional trenched water lines may take several days to a week. On average, a main water line replacement typically falls within the range of half a day to three days to complete. If you’re looking to install a new appliance or extend a water line in your home, contact Radiant Plumbing and Air for an in-home estimate.

Replacing water lines offers homeowners in Texas several notable benefits. The most immediate improvement is in water pressure; if your water line is old or deteriorating, low water pressure issues may be apparent. Replacing the water line can significantly boost water pressure, simplifying everyday tasks like using the dishwasher or washing machine. Additionally, this replacement enhances the overall plumbing system, reducing the likelihood of clogs and leaks. Newer pipes also contribute to better-tasting water, promoting the optimal functioning of plumbing systems and appliances while ensuring a fresher taste and smell from your faucets. If you’re experiencing any water-related issues, contact Radiant Plumbing and Air for a comprehensive inspection and estimates for necessary repairs to clear the water pipes.
