Bathroom & Kitchen Fixtures Install, Repair and Replace
Drain Inspection and Hydro-Jetting Glendora

Drain Cleaning and Hydro-Jetting

Professional hydro-jetting technology makes use of water pressure to help clear drain blockages while, at the same time, cleaning the insides of the pipes themselves. Hydro-jetters work quickly and efficiently and can help leave your pipes in near-new condition.

Combining hydro-jetting and video inspection, you will be able to clearly see the insides of your pipes to verify if the blockages are cleared and identify any broken pipes or root intrusion that may need further repair.

Sewer & Drain Video Camera Inspection Specialists

The cause for slow drains and frequent back-ups often occurs deep within the pipe itself, and if not diagnosed and addressed immediately, these conditions can lead to significant problems in the future. Video inspection technology is one of the safest and most minimally invasive ways to determine the exact cause and location of your pipe problems.

At McLay, our sewer and drain video inspection professionals are highly trained and have years of experience. With their technologically advanced sewer and drain video inspection equipment, they can uncover underground root intrusion, large blockages (such as severe clogs caused by years of buildup from grease, flushable wipes, and feminine products), and eroded, crushed, collapsed, or cracked pipes. Call us today to schedule an inspection. We provide sewer and drain inspection services within a 20-mile radius of La Verne, California.

Tankless Water Heaters

McLay specializes in tankless water heater installation. We are a factory authorized installer for Navien and a licensed C-36 plumbing contractor with more than 44 years of experience.

These tankless water heaters require no pilot light to heat water, and all can function immediately, providing you with the exact level of comfort that you need. Additionally, these heaters last much longer than ones that utilize a tank, and you will be able to rely on their services for upwards of twenty years.

By using a tankless water heater, you’ll not only cut down on wasted energy, which will help to reduce your monthly energy costs, but you’ll also reduce your regular maintenance costs.

Great service. These guys came out and did a great job on a plugged shower, that another well known plumbing company could not seem to resolve. The service tech was really professional and courteous.

Thanks again
