1. Introdução
This manual provides comprehensive instructions for the safe and effective installation, operation, and maintenance of your Fernco CV-150 Sump Pump PVC Check Valve. Please read this manual thoroughly before installation and retain it for future reference.
The Fernco CV-150 check valve is designed to prevent back-flow in sump pump discharge lines, ensuring efficient pump operation and extending its lifespan. It features flexible PVC couplings for connection to 1-1/4" or 1-1/2" piping and is constructed from durable thermoplastic with stainless steel fasteners.
2. Informações de segurança
Always observe basic safety precautions when working with plumbing systems and electrical equipment (sump pump). Failure to do so may result in personal injury or property damage.
- Desconecte a energia: Always disconnect power to the sump pump before performing any installation or maintenance.
- Use equipamento de proteção: Utilize equipamentos de proteção individual adequados, como luvas e proteção ocular.
- Ferramentas adequadas: Use the correct tools for installation to avoid damage to the valve or piping.
- Códigos locais: Ensure all installations comply with local plumbing and building codes.
3. Produto acabadoview
The Fernco CV-150 is a non-return valve designed for sump pump applications. It features a full-flow flapper mechanism that allows water to flow in one direction (away from the sump pump) and prevents it from flowing back, thus protecting the pump from unnecessary cycling and wear.
Figura 3.1: The Fernco CV-150 Sump Pump PVC Check Valve. This image shows the black thermoplastic body of the check valve with two flexible PVC couplings attached at each end, secured by stainless steel clamps. The valve is designed to connect to a sump pump's discharge line.
Principais características:
- Flexible PVC couplings for 1-1/4" or 1-1/2" piping.
- Full-flow flapper design for positive seal and back-flow elimination.
- Constructed of heavy-duty thermoplastic for durability.
- Quick and easy installation with stainless steel fasteners.
4. Configuração e instalação
Proper installation is critical for the optimal performance of the check valve. Follow these steps carefully.
4.1 Ferramentas Necessárias:
- Screwdriver (for hose clamps)
- Pipe cutter or saw (if modifying existing piping)
- Fita métrica
4.2 Etapas de instalação:
- Desconecte a energia: Ensure the sump pump is unplugged from its power source.
- Localize o ponto de instalação: The check valve should be installed vertically in the discharge pipe, above the sump pump and below the point where the discharge pipe exits the sump pit. Ensure the flow arrow on the valve body points upwards, away from the pump.
- Preparar a tubulação: If replacing an existing check valve or installing in a new system, cut the discharge pipe to the appropriate length to accommodate the Fernco CV-150. Ensure the pipe ends are clean and free of burrs. The valve is designed to fit either 1-1/4" or 1-1/2" PVC piping.
- Conecte a válvula: Slide the flexible PVC couplings of the check valve over the ends of the discharge pipe. Ensure the pipe is fully seated within the couplings.
- Cl seguroamps: Aperte o cl de aço inoxidávelamps on both ends of the couplings using a screwdriver. Tighten securely to prevent leaks, but do not overtighten.
- Verificar Orientação: Double-check that the flow arrow on the valve body is pointing in the correct direction (upwards, away from the pump).
- Sistema de teste: Once installed, reconnect power to the sump pump and test its operation. Observe the check valve for any leaks during pump operation and after the pump shuts off.

5. Princípios de operação
The Fernco CV-150 check valve operates passively. When the sump pump activates, water pressure from the pump pushes open the internal flapper, allowing water to flow out of the sump pit. When the pump deactivates, the water column above the check valve creates back pressure, which closes the flapper, preventing water from flowing back into the sump pit. This mechanism ensures that the pump does not have to re-pump water that has already been discharged, thereby conserving energy and reducing wear on the pump motor.
6. Manutenção
The Fernco CV-150 check valve is designed for minimal maintenance. However, periodic inspection is recommended to ensure optimal performance.
- Inspeção anual: At least once a year, or more frequently if the sump pump operates often, inspect the check valve for any signs of wear, cracks, or leaks.
- Verifique Clamps: Ensure all stainless steel clamps remain tight. Retighten if necessary.
- Internal Inspection (if accessible): If the system allows for easy disassembly, you may inspect the internal flapper for debris or obstruction. Ensure the flapper moves freely.
- Limpeza: If debris is found, carefully clean the valve components.
7. Solução De Problemas
Consulte a tabela abaixo para obter informações sobre problemas comuns e suas possíveis soluções.
| Problema | Possível causa | Solução |
|---|---|---|
| Water flowing back into sump pit | Check valve flapper not closing properly due to debris or wear. | Inspect valve for debris; clean or replace if necessary. Ensure valve is installed with flow arrow pointing upwards. |
| Vazamento nas conexões | Cl soltoamps or damaged PVC couplings. | Tighten stainless steel clamps. Inspect couplings for damage and replace if cracked or torn. |
| Sump pump running excessively | Check valve not holding back water (see first problem) or pump issue. | Verify check valve function. If valve is working, consult sump pump manual for troubleshooting. |
