Question 1

How often should drain lines be professionally cleaned and maintained?

Accepted Answer

The right interval depends on your property type, pipe age, and usage. Residential properties with older laterals and tree exposure typically benefit from annual hydro-jetting and camera inspection. Commercial kitchens and restaurants with high grease output may need grease line cleaning every one to three months and interceptor service as frequently as every week or two. Multifamily building stacks are often serviced annually or semi-annually. Tandem Mechanical assesses your specific situation and recommends an interval based on actual property conditions rather than a generic schedule.

Question 2

What is hydro-jetting and why is it more effective than snaking for maintenance?

Accepted Answer

Hydro-jetting uses a high-pressure water stream — typically 1,500 to 4,000 PSI — delivered through a specialized nozzle inside the drain line to scour the pipe walls and flush debris through to the main. Unlike a cable snake, which punches a hole through a blockage but leaves the pipe walls coated, jetting removes grease, scale, and biofilm from the full interior pipe circumference. For maintenance purposes, regular jetting keeps pipe walls clean and prevents the gradual buildup that eventually causes full blockages. Snaking is still appropriate for certain line types and smaller branch drains where jetting pressure is not suitable.

Question 3

Do you provide documentation after each maintenance visit?

Accepted Answer

Yes. After every scheduled maintenance visit, Tandem Mechanical issues a service report documenting the work performed, the equipment serviced, any findings observed during cleaning or camera inspection, and recommendations for follow-up if needed. These records are valuable for commercial property managers tracking maintenance history, for health code compliance documentation in food service operations, and for residential property owners maintaining records for insurance or resale purposes.

Question 4

Can preventive maintenance help if I already have recurring backups?

Accepted Answer

Yes, and it is one of the most appropriate responses to a pattern of recurring blockages. If a property has experienced multiple drain service calls over the past few years, that pattern typically indicates an underlying condition — root intrusion, scale accumulation, grease buildup, or pipe deterioration — that reactive snaking alone is not resolving. A maintenance program that includes hydro-jetting and periodic camera inspection will address the buildup more completely and identify whether a structural pipe defect is contributing to the problem. We often transition properties from reactive service to a proactive maintenance program after identifying the root cause of a recurring issue.

Question 5

Is grease interceptor service included in commercial drain maintenance programs?

Accepted Answer

Grease interceptor and grease trap service can be incorporated into a commercial maintenance program depending on the property's needs. Interceptors must be pumped by a licensed waste hauler when they reach capacity, but the internal baffles, inlet and outlet components, and connecting grease lines are part of the drain system Tandem Mechanical services. We coordinate grease line jetting and interceptor inspection as part of scheduled visits and can advise on pumping frequency and compliance documentation requirements for your municipality.

Question 6

What pipe materials are you able to service?

Accepted Answer

Tandem Mechanical's maintenance programs cover all common residential and commercial drain pipe materials, including PVC, ABS, cast iron, clay tile, concrete, and Orangeburg. The cleaning method and equipment used — hydro-jetting nozzle type, jetting pressure, cable size — are selected based on the pipe material and condition identified during our initial assessment or from camera inspection footage. Fragile or heavily deteriorated pipe in advanced stages of failure requires careful handling and may be a candidate for replacement rather than aggressive cleaning.

Question 7

How does a maintenance program help with health code compliance for restaurants?

Accepted Answer

Local health departments in Massachusetts and Connecticut typically require that commercial kitchens maintain grease interceptors in proper working condition and that drain systems be kept free of conditions that could cause backup or contamination. Regular, documented drain maintenance — with service reports on file — demonstrates a proactive compliance posture and can help resolve or avoid citations related to drain conditions. Tandem Mechanical is familiar with the operational and documentation expectations common to food service properties in our service area and can help operators stay ahead of inspection requirements.

Question 8

What happens if a problem is found during a scheduled maintenance visit?

Accepted Answer

If our technicians identify a developing issue during a maintenance visit — such as significant root intrusion, a cracked or offset pipe section, or a failing trap component — we will document it in the service report and discuss the finding with you before leaving. Depending on the severity, we may recommend a follow-up camera inspection for a more detailed assessment, a targeted repair of the affected section, or in cases of advanced deterioration, a conversation about lateral replacement. We do not perform additional work without your authorization, and our goal is to give you accurate, actionable information so you can make an informed decision.
