    Frequently asked questions

    • What exactly is this accessory/union fitting for? It allows the pump to be connected to pipework with the given thread, and makes it easy to remove the pump for servicing without draining the whole system (for unions with a built-in check valve/shut-off).
    • How do I check it fits my pump exactly? Compare the connection size (thread) given in the name and parameters of this product with the technical data of your specific pump.
    • Must installation be carried out by a professional? When replacing or fitting a union onto an existing system, we recommend calling in a plumber, especially if it requires draining and refilling the heating circuit.

    Chcem vymeniť staré šróbenie pri obehom čerpadle a zaujíma ma, či toto šróbenie 1"x6/4"FF s integrovaným guľovým uzáverom umožňuje demontáž čerpadla bez nutnosti vypúšťania celého systému, alebo musím systém aj tak odstaviť a vypustiť?
    A Avatar of author 25/07/2026 06:48
    Áno, práve integrovaný guľový uzáver je kľúčová výhoda tohto šróbenia – pred demontážou čerpadla jednoducho uzáver zatvoríte, čím odstavíte prietok na danom úseku bez potreby vypúšťania celého systému. Rozmer 1"x6/4" FF (female-female) znamená, že obe strany šróbenia majú vnútorný závit, pričom 1" strana sa pripája na čerpadlo a 6/4" strana na potrubie. Pri montáži odporúčame skontrolovať tesnosť spojov a použiť vhodné tesnivo zodpovedajúce teplotným podmienkam vášho systému. V prípade, že meníte šróbenie na oboch stranách čerpadla, nezabudnite, že pre správnu funkciu potrebujete vždy pár – jedno šróbenie na vstupe a jedno na výstupe.
