Plumber in Dunham Pointe, Cypress TX for brand-new homes and the warranty clock

Dunham Pointe at a glance

Dunham Pointe was started by a development team led by Archie Dunham, the former chairman of Conoco, ConocoPhillips and Chesapeake Energy. It is the team’s second master-planned community after Stone Creek in Hockley, and its largest. Community Impact places it south of US-290 between Mason Road and Mueschke Road, and the main entrance is off US-290 near the Grand Parkway.

We did not include a flood zone summary because we could not verify one for the community as a whole. Check any specific address on the HCFCD map at hcfcd.org.

What is inside a Dunham Pointe home

These are big, new houses. Builder pages show many plans over 3,000 square feet with three- or four-car garages, and Toll Brothers’ 60 ft section runs from about 3,000 to more than 3,700 square feet with 3 to 5 bathrooms. More bathrooms and longer hallways mean more plumbing: more fixtures, longer pipe runs from the water heater to the far bathroom, and more fittings in the walls and attic.

Across Cypress, homes built since the 2010s mostly use PEX supply lines and PVC drains, and that is the standard for new construction in this area. In a house this size, the layout usually looks like one of these:

New-construction PEX problems we look for

• Under-compressed crimp or clamp rings that seep slowly and leave a white or green crust.
• Lines pinched or kinked where they pass through framing or around a tub.
• Fasteners through a line from trim, cabinet or drywall crews after the plumbing was tested.
• Unsecured lines that bang when a valve closes, which wears the fitting over time.
• Debris in aerators and valve cartridges left from construction, which shows up as low flow at one faucet.
• Drain lines with poor slope or loose connections at tubs and showers, which can leak only when the tub drains.

The effect of each of these is the same: a small leak in a new wall soaks insulation and drywall for weeks before anyone sees it. In a house that may still be under warranty, the fix is usually the builder’s job, which is why finding it early matters so much. Our leak detection service finds hidden leaks without guessing.

The builder warranty clock in Dunham Pointe

Texas builders write their own warranties, but many follow a “1-2-10” pattern. That shape comes from the minimums once set in the Texas Property Code (Chapter 430, 2009 version): one year for workmanship and materials, two years for plumbing, electrical, heating and air-conditioning delivery systems, and ten years for major structural components. Your actual coverage is whatever your builder’s documents and any third-party warranty say. Treat the dates below as a typical pattern, not a promise.

If you have a leak while still under warranty

Stop the water first. Then contact the builder, because unauthorized repairs can affect coverage. If the builder cannot respond in time and water is spreading, an emergency repair to stop the damage is reasonable. Keep photos, the plumber’s written invoice and notes on what failed. We document what we find so you can send it to the builder or your insurer. For after-hours help, see our 24/7 emergency plumber page.

The pre-expiration plumbing inspection

This is the most useful thing a Dunham Pointe owner can do in the first two years. A general home inspector looks at the whole house. A plumbing-only inspection goes deeper on the system most likely to cause water damage. Here is how we run one.

1. Meter and pressure test

   We check the water meter with everything off to catch hidden leaks, and we measure static water pressure. High pressure wears out fittings, valves and appliance hoses faster.

2. Water heater setup

   We look at the pan, the pan drain, the T&P discharge route, the expansion tank, the gas venting and the flex connectors. Under IRC P2801.5, an attic or finished-space pan must be at least 1.5 inches deep with a drain, and the T&P line must not empty into it.

3. Every fixture and valve

   We run each faucet, shower and tub, check every angle stop for drips, and look for low flow that points to construction debris.

4. Visible PEX in the attic and garage

   We check fittings, supports and any line near a vent or in sunlight, and we look for signs of past seepage.

5. Drains and the main cleanout

   We fill and drain tubs and check for leaks below, test slow drains, and on request run a camera through the main line to look for debris or a poor slope.

6. Gas and outdoor connections

   We check gas appliance connections, the softener loop, hose bibbs and the irrigation backflow assembly.

7. Written findings

   You get a written list with photos and locations, ready to send to your builder before the deadline.

Caring for your first water heater

A Dunham Pointe water heater is young, so the goal is to make it last. Tank heaters typically last about 8 to 12 years, and hard water shortens that. Sediment settles in the bottom of a tank, which insulates the water from the burner, which makes the heater run longer and stresses the tank. Draining a few gallons from the valve once a year helps. If your home has a tankless unit, scale builds up inside the heat exchanger, which leads to error codes and reduced flow, so periodic descaling through the service valves matters even more.

• Write the installation date on the unit with a marker so you never have to guess its age.
• Check the pan under an attic heater twice a year and make sure the pan drain runs freely.
• Test the T&P valve per the manufacturer’s instructions; a valve that drips afterward needs replacing.
• On a tankless unit, follow the manual’s flushing schedule and keep the inlet screen clean.
• Keep receipts for any service, since some manufacturer warranties ask for proof of maintenance.

For repairs, see water heater repair. For tankless service and descaling, see our tankless water heater page.

Common plumbing calls in Dunham Pointe

In a neighborhood this new, most calls are about setup and add-ons rather than worn-out parts.

Softeners, outdoor kitchens and generators

Water softener loops

Many new Cypress homes come with a softener loop, usually in the garage near the water heater: capped supply lines where a softener can be added without opening walls. Owners in big houses like these often add one early, because mineral scale is what shortens the life of water heaters, tankless units, shower valves and fixtures. Check your water district’s annual water quality report and test at the tap before choosing a size. See water softener installation.

Gas for outdoor kitchens and fire features

Large lots and covered patios make outdoor kitchens a common add-on. Adding a grill, side burner or fire feature puts more demand on the gas system, so the line has to be sized for the total load, not just the new appliance. We size it, run it, pressure test it and pull the permit. See our gas line plumber page.

Standby generators

Hurricane Beryl in July 2024 left more than 2.2 million CenterPoint customers without power, and a May 2024 derecho knocked out power to more than 900,000. Many new-home owners added standby generators afterward. A generator is a large gas load, so it may need a bigger line from the meter and a meter review by CenterPoint. Ask your builder or HOA about placement rules before you buy one.

Irrigation and backflow in a new yard

New Dunham Pointe yards usually come with an in-ground sprinkler system tied to your drinking water through a backflow prevention assembly. That device keeps yard water from flowing back into the house supply. Texas rules call for residential irrigation backflow assemblies to be tested at installation, and retest rules depend on the water provider, so check with your district or HOA. New lawns often get watered heavily while the sod takes root, which makes it a good time to catch a broken head or a leaking valve box before it becomes a high bill.

In a freeze, Cypress MUDs tell residents to insulate pipes, shut off irrigation and know their main shutoff. In January 2026, nearby districts issued hard freeze warnings on January 21 and January 30. Wrap the backflow assembly and drain what you can. Our burst pipe repair page covers freeze prep in more detail.

Buying a Dunham Pointe resale

As the first sections age, resales are showing up next to new builds. A two- to four-year-old house can look perfect and still be past its plumbing window. Before you sign:

• Ask for the original closing date and copies of the builder warranty and any third-party structural plan, and ask whether they transfer.
• Ask for the list of warranty claims the seller filed and what the builder fixed.
• Check for ceiling stains, especially below the attic water heater and below upstairs bathrooms.
• Run the meter test with irrigation off.
• Confirm whether a softener is installed, owned or leased.
• Confirm any outdoor kitchen or generator gas line was permitted.

Sellers can help their sale by including the warranty paperwork and any plumbing inspection report. Landlords should label the main shutoff and give tenants a short note on the water heater location and the irrigation controller.

Roads and commute from Dunham Pointe

The community entrance is on US-290, with Mason Road on the east side and the Grand Parkway (SH 99) close by to the west. The Grand Parkway segment through Cypress opened in December 2013 and is a toll road. These approximate off-peak times are measured from US-290 and Barker Cypress, a short drive southeast of Dunham Pointe.

Life in Dunham Pointe

The amenity center broke ground in early 2022. Builder pages describe a family pool with cabanas, an adult lap pool, a splash pad, a fitness center and a playground, plus lakes, trails and parks. Toll Brothers mentions miles of trails around lakes, multiple pools and a clubhouse, and David Weekley’s Parkview Collection is described as the only gated section and has its own private park.

Trademark has also announced a larger mixed-use town center inside Dunham Pointe with about 225,000 square feet of retail and 500 apartments. For homeowners, that means a busier US-290 frontage over the next few years and a lot more within a short drive.

Taxes here include a district levy on top of county and school taxes. David Weekley’s Parkview page lists a 3.11815% total rate and $1,600 a year in HOA dues for that gated section. Confirm current figures with your title company.

Utilities in Dunham Pointe and who to call

Water and sewer here come from a special district, not a city. The district owns the meter and the lines on the street side. You own everything from the meter to the fixtures, including the yard line, the pipes in and under the slab, and the water heater.
