Main Water Line Repair
Long private runs and staged replacement.
About this serviceGreater San Antonio
On a Pipe Creek property the water line is not a fitting, it is infrastructure. Several hundred feet of buried pipe crossing open ground to a house, a barn and a couple of hydrants, installed by somebody who is no longer here, unrecorded. Almost every problem on a system like this comes down to two things: pressure lost to distance, and nobody knowing where the pipe runs.

A line that would be perfectly adequate over fifty feet can be genuinely inadequate over five hundred, and the arithmetic is predictable.
Friction takes pressure along the whole run. Every foot of pipe costs a little pressure when water is moving, and that loss compounds. The water arrives at the house at noticeably less than it left the meter or the pump.
Diameter matters far more than people expect. Going up one pipe size reduces friction loss dramatically, which is why an undersized long line cannot be fixed by raising the pressure at the source. Increasing pressure to compensate just stresses the whole system.
Elevation adds to it. Every foot of rise costs about half a pound, so a house sitting well above the supply point starts with a deficit before friction is counted. On hill country acreage that can be substantial.
Static pressure and flow are different problems. A long line often tests fine with nothing running and collapses when a tap opens. That pattern is friction loss, not a pressure fault, and the fixes are different.
Fittings and old valves add loss too. Each elbow, tee and partly seized valve on a long run contributes, and a line that has been extended and rerouted several times accumulates them.
Work out what the line was originally sized for. A run laid to serve one house and a stock tank is frequently now feeding a second dwelling, a workshop and irrigation, and nothing about the pipe changed when the demand did. Counting what is actually on the line explains most complaints on older acreage systems.
On acreage, locating the line is frequently the largest part of the cost of fixing it.
Most of these lines are unrecorded. They were trenched by a previous owner or a neighbour with a machine, and the knowledge left with them. That is normal, and it is worth correcting the next time the ground is open.

Plastic pipe cannot be found without help. Metallic lines can be traced. Polyethylene cannot, unless a tracer wire was laid with it, so on a plastic run the wire is the difference between a located repair and an exploratory dig.
Mark and record what you do know. A sketch with measurements from fixed points, fence corners and building corners rather than from things that move, plus photographs, is worth an afternoon and pays for itself at the first repair.
Call before anyone digs, including you. Utility locating covers the public services and will not find your private line, which is exactly why your own record matters when a post hole or a new fence is planned.
Note the depth as well as the route. A shallow section under a drive or a crossing is the part most likely to be damaged and the part you most need to know about.
A leak on a long line can lose a great deal of water before anything shows on the surface.
Valve every branch. An isolation valve where each spur leaves the main run, in a marked box, means a failure at the barn does not take the house down and a repair does not shut off everything. It is the best value item on this whole page.
Use the valves to narrow the search. Closing branches one at a time while watching the meter or listening to the pump divides a long system into sections, and that converts a field search into a defined length of pipe.
Overnight consumption is the cleanest test. With the house asleep and nothing outdoors running, any flow at all is a loss. On a well, a pump cycling at night is the same signal.
Surface signs lie about location. Water travels along the trench and surfaces at a low point or a soft spot, sometimes a long way downhill from the actual failure. The wet patch is a clue, not an address.
Judge repair against replacement honestly. A third repair on the same ageing run is usually the point at which replacing a section, in the correct size and with a tracer wire, is the cheaper answer.
Pressure is worth checking after any of this. A new section, a new valve or a repair changes the system, and confirming static pressure and flow at the house afterwards is what tells you it actually worked.
Put the valves where you can find them in winter. A valve box level with the ground disappears under grass within a season, and the moment you need it is a freezing night. A marker post at each one, and a photograph from a fixed landmark, is what makes them useful rather than theoretical.
The phone is answered around the clock, holidays included. Tell us roughly how far the house is from the meter or the pump, whether pressure is weak all the time or only when something is running, and whether you know where the line runs. If there are isolation valves you can find, say so, because we can use them.
Pipe Creek and Bandera County are on our daily route, with overnight dispatch. We measure pressure and flow before quoting pipe, use your valves to narrow a leak rather than digging speculatively, and lay a tracer wire and record the route on anything we replace.
FAQ
Friction loss along the run, compounded by any rise in elevation. Every foot of pipe costs a little pressure when water is moving, and over several hundred feet that adds up to a noticeable difference at the house.
It is the wrong fix. Raising pressure to compensate for an undersized line stresses the whole system, and the loss returns as soon as water moves. Increasing the pipe diameter is what actually addresses it.
Friction loss rather than a pressure fault. A long line can test perfectly with nothing running and collapse under flow, and that distinction changes the repair completely.
Metallic pipe can be traced. Plastic cannot unless a tracer wire was laid with it, so on a polyethylene run the honest answer is a sketch from fixed points and photographs, taken the next time the ground is open.
No. Locating covers the public services up to the meter. Your own line across the property is yours to know about, which is exactly why a record matters before anyone digs a post hole.
Not necessarily. Water follows the trench and surfaces at a low or soft spot, sometimes well downhill from the failure. The wet ground is a clue rather than the location.
With the isolation valves. Closing branches one at a time while watching the meter or the pump divides the system into sections and turns a field search into a defined length of pipe.
Usually at the third repair on the same ageing run. At that point replacing the section in the correct size, with a tracer wire and a recorded route, costs less than continuing to find it.
