Plumbing for the UNLV area in unincorporated Paradise, built around 1960s and 1970s apartments, fourplexes and student rentals, covering shared drain stacks, shared water heaters, aging supply pipe and pre-term turnover work.
The UNLV area is the University District around the campus at 4505 South Maryland Parkway, framed by Tropicana Avenue, Flamingo Road, Paradise Road, Harmon Avenue and Swenson Street. It lies in unincorporated Paradise, not the City of Las Vegas, so plumbing permits and inspections go through the Clark County Department of Building and Fire Prevention. Much of the housing is 1960s and 1970s apartment complexes, fourplexes, small multi-unit buildings and converted houses rented to students, with a smaller group of long-time owner-occupiers. Most calls here start with a tenant, but the landlord or property manager authorizes and pays, so we confirm who owns the building before the visit. Under Nevada Revised Statutes Chapter 118A, landlords must keep working plumbing and hot water in a rental.
Water heater services in the UNLV Area cover tank and tankless installation, descaling, and recirculation pump work in a corridor built almost entirely of 1960s and 1970s rental stock. What makes this work different here is the combination of multi-unit buildings where one heater may serve several households, very hard water at roughly 280 parts per million that accelerates scale buildup, and a landlord-tenant structure where the person reporting the fault and the person authorizing the repair are rarely the same. Permits and inspections run through Clark County, not the City of Las Vegas.
Tankless water heater descaling requires service valves on the inlet and outlet lines so a descaling solution can be circulated through the heat exchanger. In older UNLV-area apartment buildings, units were often installed without service valves, or the valves have seized from years of disuse. A technician must assess valve condition before quoting a routine descaling visit, because adding or freeing valves changes the scope and cost of the job.
Several apartment and fourplex buildings in this corridor run one tank water heater serving multiple units. When that heater fails or needs replacement, sizing the new unit requires accounting for the combined peak demand of all connected households, not a single-family load. An undersized replacement will run short under full occupancy, and the building owner, not the tenant, must authorize and fund the correct specification.
Installing or replacing a recirculation pump in an occupied rental unit requires advance notice to tenants and scheduling through the property manager. In this corridor, where buildings run at high occupancy through most of the academic year, early-morning appointments generally allow work to be completed before peak hot water demand. A crossover valve installation also requires access to the farthest fixture from the heater, which may be inside a tenant's unit.
Water heater repair in this rental-heavy corridor frequently stalls because the tenant who reports the fault cannot authorize or pay for the work. Establishing contact with the property owner or management company at the first call is essential. Under Nevada Revised Statutes Chapter 118A, maintaining hot water is the landlord's obligation, and framing the repair that way helps move authorization forward rather than leaving tenants without hot water while the chain of contact is sorted out.

Local Knowledge
Tankless water heater installation in this corridor should include a pre-filter where hard water calls for one, adding $150 to $300 to the job. Many older UNLV-area rental buildings have never had one fitted. Without it, scale reaches the heat exchanger faster, error codes appear sooner, and descaling intervals shorten. A property owner replacing an aging tank unit with a tankless model should confirm filter provision before the installation is quoted.
When a tank water heater is replaced in a building that has a pressure-reducing valve, the system is closed and a thermal expansion tank is required. Many older apartment buildings in this corridor were not originally plumbed with one. A replacement quoted without checking for this can result in a code-compliance issue at inspection, or repeated pressure stress on the new heater and its connections if the permit is not pulled.
A building near campus with a central water heater serving multiple units is a commercial installation for permitting purposes. Owners sometimes expect a residential-style swap, but the permit, plan check and inspection run through Clark County Department of Building and Fire Prevention, and the scope, including gas line capacity, venting and drain pan compliance, must meet commercial requirements. Underestimating this adds time and cost to a job that looked straightforward at first call.
Under the Southern Nevada Amendments, a water heater installed where a leak would cause damage, including floor-ceiling assemblies in multi-story buildings, requires a drain pan at least 1-1/2 inches deep with a drain of not less than 3/4 inch to a visible approved location. Many older UNLV-area apartment buildings lack compliant pans on upper-floor units. A replacement that does not address this will not pass inspection.
Converting from a tank to a tankless gas water heater in an older apartment building requires checking that the existing gas line and meter can supply the higher demand a tankless unit draws at full output. Buildings of this era were not sized for that load. If the line is undersized, the conversion requires a gas line upgrade, which adds cost and a separate coordination step with Southwest Gas before the installation can be completed.
What we offer in UNLV Area
When a tank water heater starts leaking from the body, delivers rusty water or simply cannot keep up, replacement is usually the sensible fix. Active Plumbing installs gas and electric tank water heaters sized to your household's busiest hour, with the venting, drain pan and expansion tank the job calls for. You get a written price before work starts, and the old unit leaves with us.
Learn more →A tankless water heater heats water as it flows through, so there is no stored tank to run out or leak. Getting one right in the Las Vegas Valley comes down to three things: sizing the unit to your fixtures, making sure the gas line and venting can support it, and planning for hard water scale. Active Plumbing checks all three before giving you a written price.
Learn more →When a water heater runs cold, leaks or flashes an error code, the cause is usually one part rather than the whole unit. Active Plumbing diagnoses gas and electric tanks and tankless units, explains what failed and whether repair makes sense, and gives you a written price before any work starts. Trucks carry common repair parts, so many repairs finish in one visit.
Learn more →A tankless water heater pushes water through a narrow heat exchanger, and valley water leaves scale behind every time it heats. Over time that scale restricts flow, triggers error codes and makes the unit work harder. Active Plumbing flushes the heat exchanger, cleans the inlet screen and checks the burner and venting so the unit keeps delivering steady hot water.
Learn more →In a long single-story house, the hot water sitting in the pipe cools between uses, so every shower at the far end starts with cold water going down the drain. A recirculation pump keeps warm water moving toward those fixtures so it arrives sooner. Active Plumbing installs return-loop and crossover valve systems and sets them up with a control that matches how you actually use hot water.
Learn more →Restaurants, salons, gyms, offices and apartment buildings each use hot water differently, so the right system starts with your actual demand. We size the equipment to your peak use, check gas supply, venting and electrical, and plan the changeover around your operating hours. You get a written price before work starts and we handle the permit.
Learn more →We check the existing tank, venting, gas or electrical supply, relief line and incoming water pressure.
We recommend a tank size and fuel type based on your peak demand, then give you a written price before work starts.
We remove the old tank, set the new one, and connect water, gas or power, venting, relief line, pan and expansion tank as required.
We leak test, fire the unit and confirm hot water, coordinate any inspection, and take the old heater with us.

Local Tips
If you manage several buildings near campus, ask for a written assessment of each water heater's age and condition during a service visit. Replacing units on a planned schedule costs less than emergency replacements and avoids the tenant complaints that follow a multi-unit hot water outage.
Before booking a tankless descaling visit for a UNLV-area rental, confirm with the technician whether service valves are present and operational. Seized or missing valves must be addressed before the descaling solution can be circulated, and knowing this in advance avoids a wasted visit.
When replacing a water heater in a multi-story apartment building, confirm with the technician whether a compliant drain pan and drain line are in place. Clark County requires one where a leak would cause damage, and a replacement that skips this step will not pass inspection.
If a tenant reports no hot water and the building runs a shared heater, treat it as a building-level fault, not a unit-level one. Contact the property owner or manager directly at the first call, because authorization and payment must come from the owner, and delay leaves multiple households without hot water.

The 40-gallon tank started weeping at the anode port. Same-day swap, seismic straps, and the old unit hauled off the pad. That call was from Lake Las Vegas. Hot water was back before the kids got home from school.

The ice machine at a clinic break room was on a garden-hose tap. A dedicated filtered line with a shutoff and a drain to an indirect receptor. That call was from The Section 10. Facilities passed the next infection-control walk.

The washer box sat too high and the standpipe siphoned. They dropped the box, reset the trap, and vented the arm. That call was from Sovana. Suds stay in the machine.

The UNLV area is in unincorporated Paradise, part of Clark County, not the City of Las Vegas. Plumbing permits, plan check and inspections go through the Clark County Department of Building and Fire Prevention, and sewer in unincorporated areas falls under the Clark County Water Reclamation District.
Drain cleaning typically runs $150 to $350 across the Las Vegas Valley. That is a typical range, not a quote. A shared stack, a camera inspection or access through occupied units can change the scope, and Active Plumbing gives the owner or manager a written price before work starts.
Active Plumbing is open 24/7, and technicians arrive in 30 to 60 minutes anywhere in the valley, including ZIP codes 89119 and 89109. Campus traffic during term and assigned apartment parking can affect the visit, so let us know where to park and who can open the unit. Call (702) 438-3357.
Under Nevada Revised Statutes Chapter 118A, a landlord must keep a rental habitable, which includes working plumbing and hot water. Report the problem to your landlord or property manager in writing. If the owner asks us to do the repair, we confirm their authorization before starting.
Many buildings here share cast iron drain stacks that scale and crack with age. Cabling clears the blockage for a while, but a camera inspection shows whether the line itself is failing. Heavy student occupancy also adds wipes, grease and disposal misuse, so simple tenant guidance helps too.
Yes. Late summer brings the heaviest move-outs, and the same jobs repeat across units: blocked drains and disposals, running toilets, worn fill valves and angle stops, and dripping taps. Scheduling those as one planned visit with the manager is usually simpler than separate calls.
At roughly 280 parts per million, the valley's water deposits scale steadily in tankless heat exchangers. Annual descaling is a reasonable baseline for units in this corridor, particularly those serving multiple occupants. A unit that has never been serviced since installation will likely need more time to clear, and missing or seized service valves may add to the cost of the first visit.
It depends on whether the building has a dedicated return line. Most 1960s and 1970s construction in this corridor does not, so a crossover valve under the farthest fixture is the practical option. The pump and control are installed at the water heater, and the crossover valve goes in the cabinet under the sink farthest from it. An outlet near the heater is also needed for the pump.
Yes, and planned replacement is straightforwardly cheaper than emergency work. Tank water heater installation typically runs $800 to $1,500 in the Las Vegas Valley. For a building where one heater serves several units, an unplanned failure affects multiple households at once. Scheduling replacements based on heater age and condition, rather than waiting for failure, avoids after-hours emergency costs and tenant complaints.
