Frequently asked questions about the PVC rainwater systems category
What are PVC rainwater systems and what are they used for?
PVC rainwater systems — are assemblies of PVC gutters, downpipes, connectors and fittings designed to collect and divert roof rainwater. They protect walls and foundations from moisture, are lightweight, corrosion-resistant and generally easier to install than metal systems.
What are the standard diameters of pipes and gutters in the PVC rainwater systems category?
The range includes standard diameters: round pipes D63, D75, D90 and D125 mm, and matching gutters and connectors such as GAMRAT TORU ÜMAR D90 and GAMRAT RENN ÜMAR D125.
How to choose between D90 and D125 for your house?
Choose based on roof area and expected rainfall: D90 suits smaller roofs, while D125 is recommended for large roof surfaces or heavy rainfall. Check compatibility with GAMRAT gutters and fittings in the product list.
What colours and finishes are available for GAMRAT PVC rainwater systems?
The GAMRAT range includes colours like pruun (brown) and antratsiit (anthracite). Pipes, gutters and corner pieces are available in these finishes to match building facades.
What components are needed to install a PVC rainwater system?
You need gutters, downpipes, couplers/connectors, fascia brackets or rennikonks, corner pieces, outlet pieces and GAMRAT fixing rings. Quantities are calculated from roof perimeter and number of downpipes.
Are PVC rainwater systems suitable for wooden or brick facades?
GAMRAT PVC systems are suitable for wooden and brick facades when using appropriate fixings: metal and plastic brackets are available for different substrates. Choose the fixing type according to wall material.
What fixing spacing is recommended for GAMRAT pipes and gutters?
Recommended spacing varies: gutter brackets are typically spaced 0.5–1.0 m apart, while downpipe clamps are placed about 1–2 m apart. Check the specific GAMRAT product description for exact values.
Can you connect components of different diameters (e.g. D90 and D63)?
You cannot join different diameters directly; use transition couplers or special GAMRAT adapters (e.g. TORU MUHV D63/90). Select the correct adapter from the catalogue.
What corner and transition elements are available for PVC rainwater systems?
Available parts include internal and external corners (RENNIOTS VASAK/PAREM), Y and T-branch fittings, couplers and elbows to change direction or join multiple downpipes. The GAMRAT range supports complex configurations.
How to prepare a parts list and calculate components for installing a rainwater system?
Measure the roof perimeter and mark downpipe locations; divide required gutter and pipe lengths into standard lengths (2 m or 3 m GAMRAT items). Include corner pieces, outlets and add 5–10% waste allowance for cuts.
How do PVC systems differ from metal rainwater systems?
PVC is lighter, corrosion-resistant, requires no painting and is easier to install, while metal offers higher mechanical strength and impact resistance. GAMRAT PVC suits fast, cost-effective installations.
Which GAMRAT colours and models are popular for private houses?
For private houses, brown (pruun) and anthracite (antratsiit) finishes are popular; common choices are GAMRAT pipes D90/D125 and 2–3 m gutters, plus matching brackets and corner pieces for a neat finish.
