tomgreen Posted December 1, 2019 Share Posted December 1, 2019 I live in a small village and our house stands alone at the end of a street , the house water supply is fed into the house from a government water meter out side the house gate . The pipe from the water meter into the house looks like ½ inch blue plastic type . The actual water supply comes from a communal water pumping station that supply's the whole village . As our house is situated at the far end of the street the piped water pressure is generally ok , but some times it increase in pressure and other times it slows right down. Our electrical shower unit has a sensor that detects the water pressure coming into the shower and if that water pressure should drop , then the internal shower heating element switches off and the water coming out of the shower head becomes cold, until the water pressure builds back up and the sensor then switches the heating element back on . During a shower this on / off hot / cold water scenario can happen several times while showering , which is driving me crazy.???? I was wondering if its possible to install a shower booster pump that would help in some way but as the water pressure to our house some times fluctuates I was wondering if installing a shower booster pump would be a good idea or just make things worse???? Any suggestions or advice welcome Link to comment Share on other sites More sharing options...
Popular Post Crossy Posted December 1, 2019 Popular Post Share Posted December 1, 2019 The proper solution would be a buffer tank that fills from the supply and pump that feeds the house from the tank. Something like this:- 10 2 Link to comment Share on other sites More sharing options...
Moonlover Posted December 1, 2019 Share Posted December 1, 2019 (edited) A booster pump would certainly solve your problem, but you would have to install a tank as well. It is illegal to connect a pump directly to the water supply. If you don't want to pressurize the whole house you can choose a small tank and a 'power shower' pump available from DIY stores. I saw some in Global House recently. Edited December 1, 2019 by Moonlover 1 Link to comment Share on other sites More sharing options...

Popular Post Crossy Posted December 1, 2019 Popular Post Share Posted December 1, 2019 If you are getting good pressure at taps on the same level as the shower it's worth checking the flexy pipes and gauze filters. If you can locate a shower with a boost pump it would likely help but I've not seen any available for sale here. 3 1 Link to comment Share on other sites More sharing options...

It’s just that I like very strong pressures to feel really clean after a shower. I have seen in HomePro where they sell electric shower units with supposedly a booster pump (or some other mechanism to boost the water pressure). 1 Link to comment Share on other sites More sharing options...
kokesaat Posted December 1, 2019 Share Posted December 1, 2019 I solved this problem. I learned to take showers with the faucet turned only half way. The water is hot and stays hot. It doesn't solve your "strong pressure to feel clean" problem, though. 1 1 Link to comment Share on other sites More sharing options...

Jan Dietz Posted December 1, 2019 Share Posted December 1, 2019 Definitely go for the tank / pump, it's not an expensive solution, 500L tank is sufficient for a normal day's use and also helps when the water is cut off for a couple of hours. Please install correctly with the valves and taps as described and you will never have an issue with the thing. It's a lot better than 'repeatedly being spat upon' by a normal Thai style shower. 1 1 Link to comment Share on other sites More sharing options...

tomgreen Posted December 1, 2019 Author Share Posted December 1, 2019 Thanks every one for your advice and suggestions. I’m not really interested in improving the water pressure to the whole house only my electric shower. ( But then again if the cost difference between the equipment / installation for improving the water pressure to the whole house Vs only my shower, is not that different , then may be the whole house idea may be better . ) so have I got this right ...

Your problem is (if the situation is not new) that your pump is too small. If it is a new problem then you need to clean out the filters on the upstairs showers 1 1 Link to comment Share on other sites More sharing options...

Crossy Posted December 1, 2019 Share Posted December 1, 2019 7 hours ago, tomgreen said: so have I got this right ... Pretty much. The non-return valve next to the pump (inside the dotted line) is usually part of the pump unit so you don't need another. Of course our Grundfos is the exception to the rule and came with a separate valve (easy to replace when it started leaking). I would be tempted to use a bigger pump if the shower is upstairs, talk to your local pump shop, they should be able to recommend a unit suitable for your home.

A couple houses I lived in had a tank and a hand "pump". Some days the water pressure was so low that I just left the faucet open for a few hours. Had to drain the tank every so often to keep mosquitoes from breeding. Warm water came from a bucket left in the sun all day covered by an old side window from a bus. I did have electricity and a light bulb in each room. 3 1 Link to comment Share on other sites More sharing options...

Thanks its appreciated In the past where I live I have had dealings with the two local Thai ‘’ plumbers ‘’ and the outcome was not a good one???? . So I’m fairly confident that I could install all the equipment my self . Ive decided the way to go would be a system for the whole house water supply . One area where I’m currently stuck is buying the right size or pump and water storage tank . We only have a small house ( bungalow style ) so no upper floors and .... one automatic washing machine one kitchen sink one toilet room with one toilet WC one hand basin and one electric shower two out side taps for a hose pipe to water the garden So overall not a big demand for water . So estimating the size of booster pump and outside water tank and plastic water pipe size is an area where I could do with some advice ????

Popular Post Crossy Posted December 2, 2019 Popular Post Share Posted December 2, 2019 A 500 or 1000 litre tank should do you, don't get one of the cheap blue ones (they can grow algae as they're not completely opaque), go for something of the sandstone or similar make. Your tank will need a nice solid base, ensure there are no stones underneath the tank to cause annoying leaks. Don't get the absolute smallest pump, I'd go for something 300 - 400W range. Your pump will probably have 1" connections, make as much of your pipework as possible that size (the tank fill size can be whatever the incoming supply already is, ours is 3/4"). Note that the cheap pumps can get noisy under load, so think about where you locate it. 3 Link to comment Share on other sites More sharing options...

Crossy Posted December 2, 2019 Share Posted December 2, 2019 The red pipe is a bypass so that you get at least some water pressure when the power is off or the pump is kaput. Some replace the NR valve with a regular stop valve which is normally kept closed, open to bypass. EDIT You may want to add a cheap polyester filter to the incoming supply pipe to keep the crunchy bits out of your tank. We have pretty clean water (we're only 500m from the treatment plant) but our incoming filter is the colour of stewed tea after a couple of months. 1 Link to comment Share on other sites More sharing options...

Thanks , the filter sounds a very good idea as I am constantly cleaning sand from the washing machine water hose filter . The pump noise I had not thought about . I am planning to install the pump and tank on a concrete base not far from our house back door where theres all ready a mains voltage power outlet. 1 Link to comment Share on other sites More sharing options...
