Bring the unit or let us source one — we install both ways.
Garbage disposal installs
Remove old unit, fit a new mounting flange with fresh putty or silicone, install the disposal with the correct trap arm pitch (1/4" per foot, never uphill), connect the dishwasher discharge to the proper port with the knockout removed, hardwire or cord-and-plug per your existing setup, and run-test under load. Hardwired installs get a dedicated 15A or 20A circuit if not already present.
Dishwasher installs done to code
A correctly installed dishwasher has either a high-loop (drain line looped up under the counter and strapped to the underside of the deck) or a true air-gap fitting at the sink — both prevent waste water from the sink siphoning into the dishwasher. We install whichever your local code requires, with new supply line, proper electrical, and leveling pads adjusted so the door closes flush.
Common problems we fix on existing installs
Disposal humming but not spinning (jammed impellers), dishwasher backing up into the sink (no high-loop or clogged air-gap), persistent leak at the disposal flange (failed putty), and dishwasher tripping the breaker (shared circuit with disposal or microwave). Most of these are 30-minute fixes.

Frequently asked questions
What horsepower disposal do I need?
For most households a 3/4 HP unit is the right balance of grinding power, noise, and longevity. 1 HP is worth it for high-use kitchens or homes with a septic system. 1/3 HP and 1/2 HP units burn out fast — we don't recommend installing them.
Why does my dishwasher have standing water at the end of the cycle?
Usually a missing or failed high-loop letting siphon back from the sink, or a clogged air-gap. Both are quick fixes, and we'll diagnose for free if we're already on-site.
Are you licensed, bonded and insured?
Yes. Nava's Elite Plumbing carries a current California master plumber registration, $1M general liability coverage, and workers' comp on every technician. A certificate of insurance naming you or your property manager is available on request before we start.
Do you give upfront pricing?
Every job is quoted in writing before any work begins. We price by scope, not by the hour, so the number you approve is the number you pay — barring scope changes you approve in writing.
Do you require money down?
No deposit on standard service calls. On larger projects (repipes, sewer replacements, gas line installs) we phase work into progress payments tied to city inspection milestones — you never pay ahead of completed work.
