    From Gordon by email:
    I am trying to replace the piston assembly on a Porcher Veneto.

    I have the replacement piece but I cant figure out how to get the old
    piece out. If you look at the diagram at


    I have parts 4 & 5 removed, but I cant seem to get part "6" unscrewed
    from the tank housing. It's loose but will not come out? There is
    obviously a nut on the other side but I cant get it free. How do I
    unscrew this bugger? Is there a tool I am missing? Do I have to remove
    the whole tank to get this out? I have the replacement pieces and it
    looks like there is a nut (unnumbered but is on the diagram) and a
    gasket (#7)

    Yeesh, I am longing for the old flapper days. Did I get a lemon in this
    porcher it has only been in for less than a year....

    Obliged for your help!

    Did you ever get this fixed? I've got a Porcher Veneto that's about 2 years old and also needs the valve replaced. What's the deal with these puppies? If they were cars, I'd think they'd be recalled

    How does the upper valve housing come off the assembly? Is it the two tabs on either side. Also, did you ever get the lower valve housing off? Finally, where did you get the replacement parts. TIA.

    veneto- Getting rid of mine-

    I have 4 of these toilets, they are nothing but costly with continuous maintenence. the piston just pulls off once you ave removed the upper portion, I have to replace this once every 6 months at a cost of $30 each, after 3 years i now must replace all the valve membranes at a cost of $18 each. The problem is the silicone gaskets which fail to seal after a while. I am planning on replacing all of them. However thet no longer sell just the gaskets. I figure I have already bought a new toilet with all the replacement parts. Additionally the lost water from the run through when the gaskets fail drives me nuts.

    Porcher Veneto Parts That Wear Out

    I got the three Porcher Veneto toilets in my house because of the fine European look, not knowing that the 2 parts that normally wear out are not easily obtained in this country, yet widely available in Europe, made by GroheDal. The shut off membrane (GROHE 4375800M), also called "membrane assembly 83086.00.000" or "diaphragm gasket" normally lasts up to 5 years and can be easily replaced by unscrewing the large white knob of the supply tower; the discharge piston (GROHE 43544000), also called "piston assembly 83084.00.000" or "flush valve" lasts longer, but is a source of water leakage due to the deteriorated silicone seal. Both can be obtained at a fair price from Guillen Enterprises in Miami, FL, and the online service is very professional. Once you have a supply of these two parts in the house, your Veneto toilet will continue to function well while adding an elegant esthetic touch to your residence.

    Just an update for all who have leaking porcher veneto toilets.. I have a 11-year old porcher, so I called Porcher at 1-800-359-3261 in regards to my leaking veneto.. They transferred me to a technical support specialist who said I either needed a new flush piston, aptly referred to as a piston assembly 83084.00.000 by ha1976, or a new membrane. They sent me both..

    My leak was due to the piston assembly (flush piston). The piston sits inside the upper valve housing. The upper valve housing comes off by twisting the upper housing counter-clockwise. When you lift the valve housing out of the tank you will see the flush piston extruding from the bottom of the housing. The flush piston can be pulled out of the housing.. Yes, it just pulls out. And you just push the new piston in place.. Secure the valve assembly back into the tank by rotating the housing clock-wise.. By the way, my veneto has two clips on the housing which secure the housing in place.

    Hope this helps. And thanks to everyone on this site who gave me enough info to fix my leaking veneto.. Cheers to the tech specialist at Porcher who helped me too.

    Thanks to 'HA1976' for the excellent information!

    Our Porcher Venetto was installed about 10 years ago and has proved to be an exceptional fixture. The flush siphon/valve is very well designed & strong. However, we have hard water (high caco3) sod I replaced the parts as a precaution. No seeps and No leaks.

    I did find the parts easily available in France/Germany but did not know the Grohe order numbers for these inexpensive two replacement parts! American Std., the parent company, supplies parts, but they're pricey. THANKS for the Grohe order numbers !!

    porcher veneto

    I've got 2 porcher veneto II's, both about a year old.

    The flushing handle sticks down on both, when flushing, unless you flush it "quickly" (push it down fast and don't hold it down long). Is this an adjustment issue or a porcher veneto personality trait?

    Also, the slow close lid on one of these puppies is now a fast slam. Again, another adjustment item?

    porcher veneto 1 toilet parts

    It seems that the flush valve assembly on my porcher veneto 1 toilet isn't working. The tank drains constantly and sometime there's a vibrating sound coming from the piston. I called Porcher and they can only sell me the piston not the entire valve assembly. I'd like to buy the whole thing so that I know the problem gets fixed. Any suggestions on where I could find a replacement full valve assembly or advice on my problem? Thanks in advance for the help!

    porcher veneto parts

    I've had 3 Porcher Venetor toilets for 9 years. I LOVE them. They are great and have been maintenance free for 9 years. I now have one that requires the membrane to be replced cause I was cleaning out the inside and accidetally ripped the membrane. The parts are easy to take out, clean and replace. Much easier than the old fashioned toilets with the flapper and chain.

    Thanks to this site and the posts, I found where I can purchase them at a resonable price, 10 for $10.95 (membrane) The Porcher is now owned by AmericanStandard, and buying parts from them is ludicrous. They're expensive and take forever to ship.

    I am however looking for a parts conversion from Porcher to Grohe, since Grohe makes the Porcher parts. Does anyone know where this can be found? I'd like to have on hand a few spare parts like the gasket. Thanks

    We have an old Porcher Veneto which has served us well, but recently it started to vibrate and shake. If I wiggle the upper valve housing, I can stop it. I'm not sure if the gasket is the only thing I need to replace or if I need to replace the whole piston assembly. Any ideas? Also, does anyone know the Grohe part numbers for these?

    Thank you very much!

    Thanks for your help

    Thanks so much for this forum! I have been at a loss to figure out why my venetto leaks. It looks like the gasket on the piston assembly has a knob on it that allows water to leak through. I can't see how a new piston assembly will change that, but I'll give it a try. I have used Guillen out of Miami once before, with very good luck.

    the fill membrane is accessed by unscrewing the big white round nut that is attached to the fill arm.... the nut is about 1 1/4 inch.. you can see it in the diagram. it has no reference number and it just above and to the right of the "9" in the diagram.
