Get those braided lines replaced, making sure that higher grade ones are used as cheap ones won't last. Replace the faucet/tap aerators as well. They can be had at Homepro these days.

 

Also, based on the OP saying he found crud in the tap aerator, if those are galvanized pipe nipples between the hidden pipework and the braided hoses, they may be really constricted with calcium build-up as well.

 

As mentioned earlier, placing a pump on a water mains inlet is illegal and you can't do it on MWA or PWA mains. Years ago on my first build in Thailand with chronically low water pressure, I placed my spare water pump on the inlet to fill my storage tank quicker. I had no problems with water pressure but my six neighbors along the cul-de-sac would only get a whistle of air from their taps when my pump was on! I then put a timer on it so that it only kicked on for a few hours overnight. After I was advised it was illegal, I doubled up on my water storage and removed the pump.

 

However, since condominium plumbing becomes the owners business once it is past the unit meter, maybe these booster pumps are permitted? AFAIK, pump-assisted commercial shower units and water heaters aren't available in Thailand. We had them in Myanmar, they were imported from Malaysia.

 

Price in Ringit?

 

Let me guess: You are connected through a VPN via Malaysia.

Perhaps the simplest and cheapest solution is to buy a shower head with very tiny holes. (Many are available on Lazada) Forcing water through a smaller hole will always increase the pressure. Think about what happens when you put your thumb over the end of a hose pipe. 

 

Forcing through a small whole will always increase pressure. Really?

In a 21 storey building the water pressure on the lower floors could be tremendous if they have water tanks on the roof  ????

It's like taking a shower with a Karcher.

Have not read all the comments but is there a filter on the inlet to the water heater that is clogged? Some have , some do not.

As mentioned by several, the first things you need to do are:

1. Turn off the main water supply in to the condo.

2. Remove the braided hoses, both hot and cold.

3. Check the fittings in the wall, these have a nasty habit of collecting dirt / rusting if not brass, a small screwdriver can be used to fish out the majority of the dirt, if you have somebody to help, then a quick on and off of the mains with flush the rest out.

4. Replace the braided hoses with good quality ones.

5. Back flush the water heater, these can get blocked with dirt, to do this, turn off the electrical power to the water heater (breaker), attach the cold water feed hose from the wall to the hot water output of the water heater, connect the remaining hose to the cold water input on the heater and put the free end in to a bucket or bowl, turn the main water supply on for a minute or so to flush the tubes out in the heater, once completed, reconnect the hoses to the correct sequence, i.e. cold water feed to the cold water input and hot water output to the hot water connection in the wall.

6. Replace the shower head and hose.

If none of this helps, then look at getting a powered shower.

Hey everyone, thanks for all the great input, especially @NanLaew   I did some research and found absolutely nothing like this available in Thailand but found high-quality units like this readily available at low prices from a Chinese manufacturer and they are willing to ship me a sample unit (based on me possibly placing a larger order) for only 2,000 THB!  Here's a YouTube video they posted:

 

 

 

It mounts in-shower, delivers a maximum temperature of 55 Celsius, and should boost pressure from what it is now, which is around 3 liters per minute to about 5 Liters.  I was hoping it would be more since the standard flow rate in hotels is usually around 7-8 Litres per minute, but maybe 5L should be OK (I'm hoping).  They say the operating water pressure for this model is 0-0.6Mpa.  I don't really understand what MPa is.  DO any of you guys have a clue if this should be sufficient?

 

Considering that I found absolutely no such products with an in-shower pressure boosting pump being sold in Thailand (i.e.: Lazada) or any of the home improvement chains, I'm wondering if maybe I should consider importing them and selling them myself on Lazada!  I think I could list them on Lazada with a selling price of around 3,500 THB. 

 

I mean there are a lot of hi-rise condominiums here where hi-floor dwellers probably have the same problem as I do.  What do you guys think...is there a market for an easy to install in-shower heater/pressure pump unit like this one?

0.6 Mpa is 6 bar.  Most home pumps provide about 2 bar give or take.

You have a work permit?
 

No? I didn’t think so.

Even if you do Thai resellers will be undercutting your price by 1,000 Baht almost instantly

With all due respect, you don't know what you are talking about with regard to needing a work permit to sell on Lazada, though I can appreciate your concerns.  I have been a selling products on Lazada for several years, and from a Thai legal perspective, no work permit is needed. 

 

Since my company is based outside of Thailand, and Lazada, a Singapore based company conducts business on my behalf with Thai consumers, I am technically and legally not conducting any business within the Kingdom of Thailand.

 

Thai consumers pay Lazada (not me), and then Lazada pays me .  Therefore I am doing business from a US based company and being paid by a Singapore based company. 

 

I consulted a Thai attorney before opening a Lazada account and what I say is perfectly correct and legal in all regards.

 

As for being undercut by Thai sellers, dealing with competition is the name of the game in successful online selling.  Currently there is no competition for this product in Thailand, but if other sellers follow me into the marketplace, I have just as much opportunity to maintain competitive advantage as they do.
