Slab Leak Detection and Repair in Tempe, AZ

Mostly SRP, with a larger share from wells

Tempe’s 2024 Consumer Confidence Report says SRP supplied about 71 percent of the water used in Tempe and Guadalupe, groundwater from eight wells about 23 percent, and CAP the remaining 6 percent. Surface water is treated at the Johnny G. Martinez and South Tempe plants. Hardness averaged 11.3 grains per gallon, but the reported range ran from 9.9 all the way to 33. The city notes that the Verde River carries more of the hardness minerals than the Salt, so the reading at your tap moves with the season and the blend. The top of that range shows how far a single source can sit from the average.

A city with no room to grow outward

Tempe covers about 40 square miles and is landlocked by its neighbours, so new subdivisions are rare and most homes have been lived in, and repaired, for decades. North of the US-60, around Maple-Ash and Mitchell Park near ASU, housing goes back well before the freeways. South of it, neighbourhoods such as The Lakes and the Kyrene corridor were built out in later decades on slab foundations. That mix means we meet original supply pipe, patched pipe and pipe replaced by a previous owner, often on the same street. Before recommending anything we look for past repair scars in the floor and check what is actually under the house.

Not every wet floor is a supply leak

In an older Tempe home, dampness at a slab edge can come from a cracked drain or sewer line under the floor rather than a pressurised water pipe. The two are tested differently: supply lines by pressure drop and sound, drain lines by camera inspection and a flow test. We work out which system is leaking first. A supply leak usually ends in a direct repair through the slab; a broken drain calls for under-slab drain repair. Either way it starts with finding the leak.

Tempe sits between Mesa, Chandler and Scottsdale, and the 101 and 202 put all three close by.
