The Doulton Under Sink Filter

Which Doulton filter is it? If it is this one (as in photo), it has a flow rate of 1/2 GPM per Doulton's specs, which equates to about 16 sec. for 16 ounces. So there is nothing wrong with the filter or installation. 1/2 gpm is kinda slow but not all that bad for drinking water only. The only way to get faster water would be to change to a large filter. Douton makes excellent filters but it's a good idea to check specs beforehand. The flow rate will also depend on the setting of your regulator. I have our Watts set at 65 psi.

I installed a Doulton ceramic filter in a 10" whole house housing. Have 3 10" whole house filters under our kitchen sink - 5 micron sediment, 1 micron Doulton and a 0.2 micron "ultrafiltration" UF filter. Flow after the Doulton filter is good. The UF filter supplies an RO type faucet for drinking water only and it is slow but better than 1/2 gpm.

On our first outing with the new sink, faucet and Doulton Under Sink Filtration System we found the water very tasty out of the Under Sink Filter. I have to say it comes at a pretty slow rate though. I would say 16 ounces takes a good 10 seconds. Which is really no big deal as we are on vacation anyway right? The upstream filter element I put in is a Scale remover and is pretty hefty. The downstream element is a ceramic/carbon for additional filtration and taste. This could be the reason it's kind of pokey. I ordered a 5 micron "gravel strainer" to replace the hefty scale filter upstream and see if that helps flow with out compromising the taste of the water. We are taking a little ride up the coast in a week and I will see what the new filter does to the flow.

Hmmmm "very tasty" to me means something is in the water that shouldn't be there.:S Purfied water should have "NO TASTE":h\

OK..........by tasty, I mean it's not foul tasting. Certainly nothing added.

Some consider no taste tasty. One mans treasure....... If they have tasty water, that's a really good thing no matter what you think.

I set up a similar dual filter system with a "roughing" & charcoal filter first then a final filter. after trying to use that, I switched to two good filters in parallel to get adequate flow.

I'm thinking all the filters are slowing it down.
I only run a carbon filter and it doesn't have any effect on flow. Thankfully that's all we need in this area.
