PD800-TAM4 remineralized alkaline reverse osmosis system showing mineral balance and pH scale

Alkaline & Remineralized Water Balance

PD800-TAM4 Remineralized Alkaline RO Water Balance

PD800-TAM4 is an 800 GPD tankless reverse osmosis system with a remineralization post-filter. After RO filtration, the TAM4 stage helps restore selected minerals and adjust the water toward a weakly alkaline level for a smoother daily drinking taste.

This positioning makes PD800-TAM4 suitable for users who want the filtration benefits of under sink RO with improved taste after mineral restoration.

PD800-TAM4 smart faucet display showing TDS OUT value and filter status indicators

Real-Time TDS Smart Panel

Smart Faucet with OUT TDS and Color-Coded Status

The built-in smart faucet provides real-time system feedback through color-coded indicators and OUT TDS display.

Instead of guesswork, users can quickly understand system status through intuitive visual signals. A color-coded indicator system shows whether the water quality and filter condition are in normal range or if maintenance is needed.

This makes daily monitoring simple and helps users know exactly when filter replacement is required.

The display also shows OUT TDS readings and system mode indicators for CP and RO operation.

NSF/ANSI 42

Improve Taste, Odor, and Aesthetic Water Quality
NSF/ANSI 42 applies to drinking water treatment systems certified to reduce aesthetic, non-health-related impurities. These may include chlorine taste and odor, unpleasant smell, and other factors that affect how water tastes, smells, or looks.
A product certified to NSF/ANSI 42 is typically chosen to improve the everyday drinking experience. However, this standard is not intended to verify reduction of health-related contaminants such as lead, arsenic, or PFAS unless those claims are certified under another applicable standard.

FAQ

Why there are many white bubbles in the water?

Normally for the first time use of the RO system, the water seems to have white bubbles in it,which is normal and totally drinkable. It is because when the pump is pressurizing the water, it will pressurize the air at the same time. It will make the air molecules smaller, thus the solubility further increases. The air can’t be released at that time because of the pressure in the RO system.
However, when you turn on the tap to get a cup of water, the pressure of air is released. So you will see a huge number of bubbles in the water. It looks cloudy and white, but they are just bubbles. After you put the water still for a while, all bubbles will be gone, the water is totally good for drinking.

TDS tester pen shows higher result than the TDS number displayed on the PD800-TAM4?

It is because the TAM4 filter, the post filter, adds the minerals to the water. Normally the TAM4 will increase the TDS by 10-30 ppm.
If the system hasn’t been used for a while, the TAM4 will restore more minerals to the water, and at that time the water is very good, the PH level will be more than 9.

Why TDS is higher at the beginning, but back to normal range after about one minute?

Osmosis is a natural phenomenon that happens in all RO systems, no matter if you have a conventional RO system or tankless RO system.

When the RO system starts to work, pressure from the pump overcomes natural osmotic pressure, forcing feed water through the RO membrane that removes the impurities.

When the RO system stops working, the pump stops offering pressure as well. At that time, because of different concentrations, a small fraction of ions will enter into pure water and cause TDS to rise by a small amount.

However, even if the TDS reading is a little high at the beginning, the water quality is still unbeatable by any other filtration methods including carbon, KDF, ceramic, UF, UV, etc. The water is totally safe to drink, and you don’t have to wait for about 1 minute to get the water, since the whole system will not release any harmful substances to the water.

The TDS removing rate for PD800-TAM4 is about 94–95%. If your incoming TDS is high, the outlet TDS will be high too.

How does the TDS display on the machine work?

When the system is running, the TDS sensor in the PD800-TAM4 will keep testing the water quality every 1 minute. Therefore, the TDS result you see from the machine is from the last test memory.
If you want to have the real-time TDS result, please let the machine run for about 1 minute.

If I don’t want to use the TAM4, how should I disconnect it?

You don’t have to disconnect the tubing and the fittings on the TAM4. You only need to unscrew the TAM4 filter and the water still can go through.
