Urgent Plumbing Problems
Water spreading across the floor or sewage backing into a shower needs prompt attention. If you are looking for an emergency plumber in Washington, IL, Arnold & Sons offers 24-hour scheduling so you can report the problem and ask about the next available appointment.
For an active supply-pipe leak, turn off the home’s main water valve if you can reach it safely. If wastewater is backing up through several fixtures, stop using water until the blockage can be professionally evaluated. If you’re looking to shut off your main water valve because of flooding, keep clear of standing water near outlets, appliances, or electrical equipment. When in doubt, reach out for professional assistance before doing anything.
Plumbing Repairs
A plumbing problem can interrupt the whole household even when only one component has failed. Our plumbing repair services cover damaged piping, leaking connections, and fixtures that no longer work as they should.
Leaks and Damaged Water Lines
Finding the source of a leak is not always as simple as following a wet spot. Water can travel along framing or beneath flooring before it becomes visible. Leak detection helps our plumbers narrow down concealed leaks and determine where access is needed.
During Central Illinois cold spells, plumbing in unheated or poorly insulated spaces can freeze. If a pipe splits, the leak may only become apparent as it thaws. For these situations, we provide burst pipe repairs and inspect the affected area for other damaged connections.
Problems between the house and the public water supply require a different investigation. A persistently wet yard or a sudden household pressure change may warrant checking the service line. Arnold & Sons handles water-line break repairs for piping that falls within Washington, IL homeowners’ responsibilities.
Kitchen and Bathroom Fixtures
A toilet that keeps refilling or a faucet that will not shut off properly can waste water every day. Our plumbers provide toilet repair, kitchen faucet repair, and bathroom faucet repair to address worn parts, leaks, operating problems, and more.
We also service garbage disposals and help homeowners plan kitchen and bathroom plumbing upgrades. When replacing a fixture, we always make sure it’s perfectly integrated with your existing plumbing.
Drain Cleaning and Sewer Repair
Arnold & Sons provides drain cleaning in Washington, IL, alongside broader sewer services.
Clearing Clogs and Cleaning Sewer Lines
Hair, grease, soap residue, and other debris can interfere with drainage as they accumulate. If you’re dealing with clogged drains in Washington, IL, we can get your plumbing flowing again. Cabling can break through many obstructions, while hydro jetting may be appropriate when buildup remains along the pipe walls. We’ll recommend the appropriate drain cleaning method according to your needs.
For root-related sewer blockages, clearing the roots is only part of the assessment. Roots enter through openings in the pipe, so we also look for cracks or failed joints that could allow the problem to return.
Sewer Line Repair
A broken or misaligned sewer pipe can catch waste and cause repeated backups, even after the line has been cleaned. Arnold & Sons uses camera inspection to look for cracks, separated joints, and collapsed sections that may be interfering with drainage.
Our sewer line repair services in Washington address those physical defects. If damage is limited to one area, replacing that section may be enough. If deterioration extends farther along the line, we explain why a larger replacement may be needed, how we would access the pipe, and what disruption to expect before work begins.
Water Heater Repair and Replacement
Losing hot water does not automatically mean you need a new water heater. A failed heating element, ignition problem, or faulty control may be repairable if the rest of the unit remains in sound condition.
Arnold & Sons provides water heater repair in Washington, IL, checking the source of the failure alongside the equipment’s age and repair history. If the tank itself leaks or deterioration makes another repair difficult to justify, we will explain the replacement options.
Choosing a new water heater involves more than matching the old tank’s size. Household demand, available space, fuel supply, and recovery rate all affect whether the replacement will keep up.
We also install tankless water heaters. These systems heat water as it passes through the unit, but must be sized for the fixtures you expect to use together and the temperature rise required.
Sump Pumps and Basement Water Protection
Our sump pump services include evaluating how the system collects and removes water, replacing failing equipment, and discussing backup protection. For a basement that depends on pumping during wet weather, checking operation before heavy rain is a practical precaution.
Water Treatment
Arnold & Sons provides the following water-treatment services to help match homeowners’ needs with the appropriate equipment.
Softening and Whole-Home Filtration
For Washington homeowners dealing with hard water, a water softener can make everyday cleaning easier. By reducing calcium and magnesium, it helps limit chalky deposits around faucets, mineral spotting on dishes, and soap scum in showers. Soap also lathers more readily, which can reduce the amount needed for washing.
Softening helps limit scale inside water heaters and other water-using appliances, too. Arnold & Sons sizes and adjusts the equipment according to measured hardness and household consumption so it can keep up with daily demand.
Whole-home filtration addresses different concerns by treating water before it reaches the home’s fixtures. A sediment filter can capture particles that otherwise collect in faucet screens, while suitable carbon filtration can reduce chlorine taste and odor, making tap water more pleasant for drinking and cooking.
A household experiencing both mineral buildup and unwanted tastes may benefit from combining softening with filtration. We help determine which concerns are present and select equipment to address them.
Drinking-Water Systems
A point-of-use system gives you filtered water where you fill glasses, prepare meals, and make coffee. Installed at the kitchen sink, it can be a practical choice for Washington homeowners who want better-tasting drinking water without treating every faucet in the house.
The specific point-of-use system we recommend will depend on your needs. A carbon filter can reduce chlorine taste and odor, while a reverse osmosis system uses a membrane to reduce dissolved salts and other substances that basic carbon filtration may leave behind.
