One of the most common questions plumbing contractors and apartment owners ask is: What’s better for a renovation — press-fit, threaded, or Push-Fit? The answer depends on the type of project, the scope of the renovation, and access to the existing piping. SP Industries provides three complete systems for every scenario — from new construction to localized renovation. This guide will help you choose correctly and save money.

New construction: mandatory rules
In new construction, you have the greatest flexibility when choosing a system. The important rules:
1. Choose one system and stick to it:
Do not combine press-fit and threaded connections in a concealed installation within the same apartment.
2. Plan the diameter in advance:
According to Israeli Standard 1205.1 – 1 point = 16 mm, 2–3 = 20 mm, 4–9 = 25 mm, 10–16 = 32 mm.
3. Prepare the manifold cabinet in advance:
Prepare the space in the wall before the concrete is poured. The SP cabinet (770506) must be installed at least 30 cm above the concrete floor.
4. Pressure test before covering:
It is mandatory to perform a pressure test before any pour – 15 atm, one hour, drop to 0.5 atm.
Renovation: challenges and solutions
Renovation presents challenges that new construction does not:
Challenge 1: Existing piping of a different type
Old piping may be galvanized, copper, or old PVC. SP Industries allows connection to any type of existing piping using threaded connectors, bushings, and transition fittings.
Challenge 2: Minimal cutting
The SPEX solution enables pipe replacement without cutting into walls — you can pull out the old pipe and insert a new one through the existing conduit.
Challenge 3: Localized renovation
SP threaded connectors allow point-to-point connection to existing piping, including:
- Double nipple ½"-½" (part no. 770051) – ₪11.70
- Female/male bushing (part no. 770061) – ₪21.70
- ¾"-½" shower mixer T connection (part no. 770058) – ₪21.10
Professional tip: Push-Fit EF-SP for renovations
Push-Fit EF-SP is the ideal solution for targeted renovations:
- ✅ No press tool needed — immediate installation
- ✅ Disassemblable — quick repair
- ✅ Reusable — material savings
Perfect when you need to replace a single connector without buying an entire press tool.
Repairs after renovation – mandatory rules
With press-fit fittings:
- Leaking fitting → replace the fitting together with the pipe section — no re-pressing
- Damaged pipe → replacement from end fitting to end fitting
With threaded fittings:
- Leak at the connection → tighten loose connectors
- Leak between the sleeve and the pipe → replace the sleeve
- Damaged pipe → full replacement
Required after every repair: repeat pressure test.
Required before occupancy: full pipe flushing.

Frequently asked questions – renovation and construction with SP
Can SP piping be connected to old copper piping?
Yes. SP offers a range of transition fittings and union connectors that allow direct connection between SP and existing copper, galvanized, and plastic piping. For example, the SP-compatible union connector (part no. 780181) for 16 mm × ½" connection.
Can a water point be added during a renovation without opening the entire wall?
Yes, with SPEX — an existing pipe can be pulled out and a new pipe routed through the same conduit, with minimal cutting. For a completely new point, only minimal cutting is needed for the pipe route.
What is the difference between renovation with press-fit and threaded connections?
Press-fit — fast, reliable, excellent for full renovations, but requires a press tool. Threaded — suitable for localized and exposed connections, and can be connected to old piping without special tools. Push-Fit — ideal for repairs and localized renovation, with no tools required.
Is a pressure test mandatory in a renovation?
Yes. In every project — renovation or new construction — a pressure test must be performed before covering the piping, and again after every repair. Without a proper test, SP’s warranty does not apply.
