Cleaning and clearing, inspection, and repairs! Zoom Drain is a full service provider of residential & commercial drain cleaning and inspection. We’re best known for fast response times and our ability to provide focused solutions to drain & sewer problems. From sinks, toilets, and tubs to main drains, roof drains, storm drains, and anything else that carries water, we’ve got you covered. We also offer grease trap cleaning services and planned preventative maintenance.

"Extremely customer service experience. The representative I dealt with was not only unhelpful but also came across. As both judgmental and lacking professionalism when I asked clear questions about pricing I received vague misleading answers. They scheduled an appointment that I had agreed upon for one o'clock pm but no one show up or call. Instead I received a text for 1 o'clock pm.; When I called to let them know The situation and the pricing they have changed their answer from 1 -3pm and told me that there was a fee that would be applied. When I asked a follow up question the Rep. hung up on me. The overall behavior was unprofessional and extremely biased based on demographic that they choose not to served. I would expect more transparency, respect and communication."

Our Service Plumbing team is ready and willing to tackle your project - be the need immediate or not. Simply reach out and we will dispatch a technician immediately to provide a quote and solve your problem!

"Only rating 1 because it doesn't go lower. Had a new unit installed end of Sept 24. First time power goes out on 11/5, no electricity. When tri state sells you a product, they pitch their amazing customer service with all these guarnatees of knowing when your unit is out before you know and having someone there within 24 hours etc. Well, the first call we make we are told it will be the end of Nov to get someone out to look at it. 3 weeks. Nobody shows up. Then we get a call that says "your appointment on Dec 12 has been canceled and the earliest we can get to you is Jan 16th. This is 2.5 months wait to get service to fix a nearly $20k unit, that is upcharged because of the excellent service. You can't get anyone to answer your call. you wait on hold for 20 minutes, then have to leave a voicemail in which you will not get called back. Based on my experience, find someone else and pay less. Even if the service is bad, which it can't be worse than this, you save money! @kohler"

Boiler Repair questions, answered by experts

Yes, it is OK to turn off some radiators, and you’ll save money on heating costs if you make it a regular habit to turn your radiators off in unused rooms that don’t need heat. That said, turn them back on when you need to heat your whole home instead of cranking up the dial on the ones you haven’t closed to compensate. The latter will result in higher heating costs and more wear and tear on your system.

One of the most common signs you’re dealing with a bad thermocouple is the pilot light for the water heater will continuously go out. For example, you may light the pilot light and then have to re-light it a few days later. You can also look at the thermocouple for a visual inspection. If you notice discoloration, cracks, holes, or other damage, then you know it needs replacing.

You’ll want to bleed your radiators at least once per year, typically in the fall before you plan to turn on the heat. Bleeding a radiator is a regular part of your heating system maintenance, and you’ll need to do this regularly to keep these units running efficiently. You should also bleed radiators any time they start making noise, like gurgling, hissing, or banging.

Even if you do everything right, your boiler’s pilot light might not come on. This has a number of possible causes, but the most common is a blocked jet. These jets are small and clog up even with a small amount of debris. You can clean it yourself or hire a pro to replace the component. Other possible causes include a faulty fan and frozen pipes, among others.

Most propane boilers last 15 to 20 years with regular maintenance and proper care. The lifespan depends on the quality of the unit, proper installation, and the level of maintenance. Investing in annual service can maximize longevity and efficiency. Routine inspections and timely repairs prevent early breakdown, ensuring your boiler heats your home for years to come.
