Services & Process

Frequently Asked Questions

What is a backflow preventer and why does it need to be tested?
A backflow preventer is a device that stops contaminated water from flowing backward into the clean water supply, which can happen when water pressure drops. Most municipalities require annual testing by a certified contractor to confirm the device is working correctly and to maintain compliance.
Can J Whalen and Son handle both my septic pumping and backflow testing in one visit?
When a contractor offers both services, scheduling them together is often possible and cuts down on the number of appointments you need to coordinate. Call ahead to confirm availability and give them a heads-up that you want both services handled on the same day.
How does excavation factor into a septic repair project?
Most septic repairs, especially anything involving the tank, distribution box, or drain field, require digging to access the components. Having an excavation contractor on the same team as the septic technician means the work gets done without delays waiting on a separate crew.
Is Pennington served by public sewer, or do most homes use septic systems?
Pennington Borough itself has public sewer in many areas, but surrounding Hopewell Township and rural sections of Mercer County have large numbers of homes on private septic systems. If you're not sure which system your property uses, your county health department records can confirm it.
How do I find out when my septic tank was last pumped?
If you have records from a previous service, those are your best reference. If not, the county health department may have records on file, or a technician can assess the tank's sludge level during a visit to estimate how long it's been since the last service.
What's the typical cost range for septic tank pumping in Mercer County?
Residential septic pumping in New Jersey generally runs between $300 and $600, depending on tank size, access difficulty, and the service provider. Getting a quote upfront before the job starts is always a smart move so there are no surprises on the bill.
