Grohe 43 544 000 Discharge Piston (06217800)

The local plumbers don't know Grohe and it was hard to find just this toilet piston valve on its own without paying a silly at a boutique (?!) plumbing store. I found the right part on Google (took forward) and searching again got me a link to Amazon. Works perfectly, still watertight, zero effort to install. I found myself using the expression "Amazon wins again."

Part worked great (stopped leak between the tank and bowl), saved the expense of doing what the toilet manufacturer had recommended which was buying an entirely new flush valve, which was almost 10 times the cost of this part.

30 year old Porcher toilet. Tank water leaked into the toilet and every few minutes the supply valve had to top off the tank level. This part contains two small diaphragms that need to be renewed. I could not find them separately except one site in the UK, notwithstanding this part and the diaphragms are Grohe parts originally.

Hard to find locally. Once installed it worked like a charm

This fits my badly leaking porcher toilet with the top push button perfectly, it is the complete flush unit and includes both the bigger bottom seal and the smaller top seal. The only down side is that it doesn't include detailed instructions other than some wordless drawings. Hopefully the seals on here would last longer than the seal on the original unit. Not too hopeful though, because they seem to be made from the same silicon gel like material.

Perfect replacement for the piston in my Porche toilet.

Good quality and product as described.

Works great

It works. My cistern is fully operational now.

Article conforme à la description.

Perfecto, sin problemas. Es curioso que Amazon tenga este producto técnico tan especial, orientado a usuarios también especiales. Amazon me ha ahorrado una tarde entera de peregrinación por la ciudad

Excellent works as intended.

Installato in una cassetta di 26 anni fa contrassegnata con codici diversi ma di fatto stesso modello. Sostituito vecchio pistone la perdita si è subito arrestata. Spedizione veloce. Problema risolto.
