Hot water dispensers: What is the difference between a close or open vented faucet models and which are better and why?
1818193
Open vent faucets allow the "instant hot" tank to run without a temperature and pressure relief valve as is found in your domestic hot water heater; the tank normally runs at atmospheric pressure (is vented through the faucet spout itself) and is only pressurized to the extent that when you open the hot water dispensing valve you are actually allowing cold water to enter the tank thus forcing hot water out through the spout, which is always open through to the tank. When you release (close) the hot water dispensing valve the cold water supply to the tank is once again shut off, ending the flow of hot water and leaving the tank vented through the faucet. This method of avoids/solves the problem of providing a safe method and place to vent a tank overpressurized as a result of a stuck thermostat.

There are two base models. One has a higher flow rate than the other. That means that more water can be moved faster that the other. But both flow sufficiently well for most enviorments. The other things that are added may be desired for some applications. You need to check with you local plumber to see what is required in your area.

The 00100 is insulated, the 00085 is not. The 00100 features a slightly fancier faucet as well; both unit's faucets are Tomlinson No-Drip. The best you can buy. (The insulated version has TWO basins that nest, providing insulation.)

I have the 8800 and love it. I think the only difference is that the 9000 takes up less space on the counter. It appears that you pour the water in the top with the 9000, but with the 8800 you just fill the left side container and it ends up in the dispenser container on the right. Thats about the only difference I can see. The 8800 shuts off automatically when done. I assume the 9000 also does. Hope this helps

The adjuster is designed to ensure that your vent closes completely when installed. You will need to run it down a bit initially and then adjust accordingly for your specific vent application once installed. The advice to refrigerate the closer is paramount, so that you can accurately adjust for the closed position.

Overall, I am very happy with the faucet and would buy it again. Though there is a difference in the cold v. hot water with hot being less powerful than the cold. I think this has more to do with the way it was installed. I had other problems with my contractor so I believe the difference is due to the way they installed it. Hope this helps.

It's more cosmetic than anything. You can't see the open portion of the shower tower unlessinstalled you hadthe a stepgood ladder. Water doesn't get into that part of the tower so quick drying isn't necessary. The one advantage to the open design is that it would allow you to replaces hoses much more easily since there isn't a back cover.

the 2570 has an extra pair of shutoff valves (one for cold and one for hot) where water can be shut off upstream from the main valve (what the handle controls). This is handy if you ever have to service or replace the mixing/main shutoff valve cartridge inside as they wear out, without having to shut off the water to the house. I just bought 7 of the 2510 valves because they were 10 bucks a valve cheaper and the parts in them are good for years between replacements. I can deal with turning off the water to the house every 5 years or so to replace the valve cartridge.

I think neither. We just pout hot water into ours. I believe the center diffuser is metal.

There is a comparison chart of several pourers online and I believe you will find it useful. Here is the link: www.pouro.netI found a great pourer there called Amazing Pourer that can be opened or closed with a simple twist. I tried it and they are the best for me.

I would suggest consulting a plumber. I have had two Titans in the past 14 year and both have worked well for the entire townhouse. Its only "shortfall" is the temperature drop-off if a second faucet is opened simultaneously. Here in South Florida the base water temperature is high enough that a "cold shower" is not cold by most standards.

The only difference I know is the cup/bowl included at a little higher price. The idea of the Hot Shot is a good one. This newer version often leaks. I find the ones I purchased all leak. It is hard to find the earlier version. To recognize it, it has operating levers at the front bottom of the reservoir. It is model 3211. I don't recommend this newer one. You'd be better off with an electric kettle.

Sorry can't help you as I put both faucets in a remodel house I do not have access to at this time I will say I put the both sets on a predrilled granite top and they extremely easy to install. There was not an excess of overlap on top - even pushing the valve to the side did not show any sign of the hole from beneath. Very happy with them. I have also installed several others from Pfister and have been happy with them

I have not noticed any difference, I don't know technically if it does. I have not found any where that has allowed air to pass being that it had pulled away . I was just running new water and sewage lines in the basement and was inspecting for air leaks of places that I missed on the original install. I found none. You might want to contact the manufacture for technical data. They were very helpful and addressed all questions. I used the closed cell exclusively . Full fill . I can tell I am BLOWN AWAY with the low cost of my heating this year so far. I have used only 1/4 tank of oil. I keep that house at 70 degrees. I live in western pa. Hope this helps

Untreated water means not directly from the faucet. I've used store bought distilled water and I've used boiled tap water. I prefer the boiled tap water - I do extra water - I let it cool before using in the pump and use the extra to flush out the system when done. It is a pain waiting for the water to boil and then cool, but it gives better control over the temperature of the water. I find the distilled water cold and have to warm it anyway.

The manual does not offer any plumbing recommendations. I plumbed my unit setting the 1/2" FIP hot and cold lines 22" above the floor and 3" apart. I am 6'3" tall and this height put the shower head 10" above my head. Watch door clearance if your shower door opens inward like mine (ie: higher is better). This feed line location will still offer you at least 6" variation on the actual unit height as the unit itself is connected using flex hoses. One other tip not mentioned in the manual, The temperature valve (bottom knob) has a safety feature that only lets the water get to warm. Just push the small tab on top and it then allows full hot operation (this is not documented either). The manual does not offer any plumbing recommendations.

I can't remember all the differences now. It can be confusing! I went to a plumbing store that had all the choices displayed so I could see exactly what I wanted and also got a brochure. Both things helped with the choice of finishes, which was my main concern. This is my second Grohe faucet and I am very happy with it. I like this pull-down because it fits my hand nicely and it looks great in my kitchen.
