Monmouth Heights, off Route 79
Monmouth Heights is a housing development and unincorporated community inside Marlboro Township. It sits along Route 79, across the highway from Marlboro High School. It was built in the 1960s by Levitt and Sons.
Real estate sources also use the name, and township records list Monmouth Heights among the township's unincorporated localities. We could not find a published boundary map, so we describe it by Route 79 and the high school and nothing more precise.
What a 1960s date does and does not tell you
A development from the 1960s has had many decades of repairs, additions and remodels. Some homes have kept parts of their original plumbing and many have not. Nobody can say which without looking, and we do not assume problems on the basis of age.
What the date does suggest is that older fixtures, shutoff valves and water heaters are worth a look when you are already calling a plumber. A quick check of the valves under sinks and the age of the water heater costs little and can prevent a surprise.
- Check that shutoff valves under sinks and behind toilets turn and do not weep.
- Find the date on your water heater data plate.
- Note any rust colored water that comes back after running the tap.
- Look in the basement for stains on pipes or beams.
Inspect first, then decide
When an older house has a plumbing problem, the first goal is information. A camera can show the inside of a drain or sewer line. A meter test and a listening tool can show whether a leak is inside the house or outside. Only then does a repair or a replacement make sense.
Our sewer inspection and leak detection pages describe those visits. If an inspection does show widespread trouble, our repiping page explains how a replacement is planned.
Cost matters too. If an inspection shows only one failed section, a targeted repair is often all that is needed. We explain what the camera or meter test found and what each option would involve, so you can choose with the facts in front of you.
