Technical Help

If your irrigation line is leaking, pulling apart or not matching the job, start here for clear advice on the right fitting and the right jointing method. PVC Welders supports farmers, landscapers and contractors with practical guidance from Ladanna, Polokwane to help keep water moving where it should.

Start With The Pipe And Pressure Rating

The first step is to match the fitting to the pipe size, pressure class and the way the line will be used. A join on a garden line is not the same as a mainline feeding a block of sprinklers, and a pressure mistake can lead to split joints or repeated leaks. In hot inland conditions and on open farm runs, PVC also needs proper support and clean preparation before any solvent is applied.

If you are unsure, send the pipe size, the fitting type you need and the working pressure on your system. We can help you check whether the parts are suited to drip, sprinkler or transfer use, and whether you need a standard socket, reducer, elbow, tee or end cap.

  • Confirm pipe diameter in millimetres before ordering
  • Check the pressure class on the pipe and fittings
  • Tell us if the line is buried, exposed or on a pump system

How To Get A Clean Solvent-Weld Joint

A good joint starts with a clean cut and a dry fit. Trim the pipe square, remove burrs and wipe away dust, sand and moisture. On dusty sites around Polokwane, or where the pipe has been stored near the veld, a quick clean makes a big difference. Use the correct primer and solvent for the joint, then assemble without delay.

Push the pipe fully into the socket with a slight twist and hold it in place for a few seconds so it does not spring back. Wipe off excess solvent, but do not disturb the joint once it has been made. Let the joint cure before pressurising the line, especialy on larger diameters or in cooler weather.

  • Cut square, do not angle the pipe
  • Dry fit first to check alignment
  • Allow proper curing time before testing

Fitting Choice For Common Irrigation Problems

Different site problems call for different fittings, and choosing the wrong one can waste time on the farm or at a landscaping job. If a run changes direction, an elbow keeps the line neat. If you need to split flow, a tee is the usual choice. If one section must be isolated, use the right cap or valve connection. For repairs, couplings and repair sleeves are often the quickest fix.

For contractors working across Limpopo, stock planning matters as much as the fitting itself. It helps to keep a small reserve of the most used sizes on hand so you do not lose a day waiting for one part. We can also help with quantity checks for bigger orders, so the site does not stop halfway through the job.

  • Elbows for turns and tight corners
  • Tee fittings for branch lines
  • Reducers for changing pipe sizes
  • Couplings for straight repairs

Troubleshooting Leaks, Pull-Outs And Weak Flow

If a line leaks soon after installation, the cause is often poor cleaning, not enough curing time or a joint that was not fully seated. Pull-outs usually point to movement in the line, bad support or pressure that is too high for the parts used. Weak flow can come from a blockage, a wrong fitting size, or a line that has too many bends and restrictions.

Before replacing parts, isolate the affected section and inspect the pipe ends, sockets and seals. Check for cracks, oval cuts, glue contamination and any soil or grit inside the joint. If the problem keeps returning, we can help you work back through the line and narrow down where the fault starts.

  • Look for visible moisture around joints
  • Check for movement at support points
  • Inspect for hidden cracks after pressure testing

Advice For Farms, Estates And Contractors

Every site has its own pressure, distance and water quality issues. On farms, long runs and pump changes can affect joint stress. On landscaping jobs, the line may need to be neat and easier to service later. In coastal areas, humidity and salt air can make storage and handling more important, while inland sites may face heat and dust that affect fitting prep.

We support repeat orders, contractor accounts and farm order planning, so you can keep a regular stock of the parts you use most. If you are sending a team out to a remote area such as Lephalale, Thohoyandou or Hoedspruit, it helps to confirm the full list before dispatch so nobody arrives short on fittings.

  • List the job type and site location
  • Send pipe sizes and counts for each line
  • Ask for stock reserving before collection or courier dispatch

How To Ask For Help Through The Contact Form

The quickest way to get practical support is to use the enquiry form on our contact page and give us the details in one message. Include the pipe size, fitting type, problem area and whether you need delivery in Polokwane, Mokopane, Tzaneen, Hoedspruit, Lephalale, Thohoyandou or further afield. Clear information helps us answer faster and avoid guesswork.

If you are dealing with an urgent repair, say whether the line is already installed, whether water is off, and what parts you have on site. That makes it easier to guide you on the next step, whether it is a replacement fitting, a jointing check or a troubleshooting call-back. We keep the advice practical, so you can get on with the job without extra runs.

  • Use the contact form for all support requests
  • Include photos or a clear part list where possible
  • State if the order is for pickup, regional delivery or courier dispatch

Questions we get asked

What details should I send when asking for technical help?
