How To Fix Your Low Water Pressure Problem

Your mentioning of the important terms (flow rate and static pressure) as well as their description is VERY MUCH APPRECIATED. You are the first plumber who shows a sound understanding of his trade (profession really) I have ever come across.

Hi Roger Thanks for explaining how these boosters work and the pump. The way you explained in every detail in depth and not only that and you went further to explain how to install it. This is the best of the best videos I have seen then other people's videos.

High end new builds with multiple bath facilities will of course come with all this factored in and kitted out, but of course existing older housing stock can experience issues over time as they put in attic extensions, en suites, and additional wet rooms, so this information is great for people to know.

Brilliant! Thank you for sharing this video! Simple, Clear & Practical with a lot of well defined valuable experience! You sound like my late father who was a carpenter by trade with plumbing experience! I lost him a few years ago at the age of 94 years! Thank you again and greetings from Madang, Papua New Guinea!

Hi Roger, accumulators have been in use for many years in commercial buildings - hotels, pubs, schools and so on. They are very effective. Love all your videos, and opinions!

Really informative for me thanks! I moved into a house and have what I think is a similar unpumped device in my loft. It only supplies 2 showers and the hot water.

It’s usually good practice to take a flow rate from a non restricted tap such as an outside tap ….most kitchen taps / basin taps tend to have reduced flow rates these days! Good video roger

Great information - Thankyou! Also reminds me of my disappointment when replacing our bathroom. Knowing we had crap water pressure, I very carefully replaced the hot piping to the bath in 22mm all the way - even using formed bends to reduce resistance - then unpacked the new tap to find the risers had pathetic 8mm bores!!

Hi Roger love your plumbing videos I ran a heating contractors for 30 years in south London and always dealing with flow and pressure problems particularly in Balham and Brixton notorious for low pressures sometimes only 1 bar These accumulators solved many problems for me. One add on tip for you, where even one of these devices would improve but not completely, solve a problem, is to fit balancing valves on the supplies to the individual outlets (just a gate valve with the handle removed) Then similarly to balancing radiators, you can restrict restrict the greedy to favour the needy I used to find it was always the showers, usually at the higher parts of the house, that would suffer to some extent sometimes even after a booster. The combination of booster and balancing was needed on some of the toughest nuts I had to crack with very demanding clients in these expensive areas…..

Amazing, sounds like it would fix our flow issues. Wish I knew about these years ago.

That 450 litre tank will weigh nearly half a tonne when full so take care where it's sited - a wooden floor may not like the extra load !

Hi just a quick comment, being a building service engineer, I noticed you incoming mains at the start of the video,that your strainer should be positioned on the horizontal, with the filter facing downwards, or on the vertical with the flow going downwards, but never facing upwards as its installed - Im sure manufacturer installation guidance will verify this -see Hattersley valves as a guide. Apart from that, excellent videos and tips. You certainly have trade experience and it shows in your excellent videos and trademanship.

Great video, been considering an accumulator after changing pumps on a tank system (original pump 20 years ago is spec'd less than current pump and the new one can't keep up with 90% of the house now and water blaster sure when under pressure) Technology gets better but not always production.

No issues with water flow and static pressure here, static pressure is between 8,5 and 9,5 bar which is quite high. A pressure regulator is needed to bring it down to 4 bar in the house. For the garden I do have a 22mm pipe run of before the pressure regulator, the tap on that pipe fills a bucket in 10 seconds, so about 50l / min. But there is another advantage to the accumulator, that's if the water main supply fails. There is enough water in the accumulator to get taps and toilets going for quite a time.

Thank you for a grand explanation , just a mere sparks .

Thanks for the great info. I think I may have a solution to our problem with our water flow. Personally, I think these should be installed in all homes during the build process. Thanks, Guv'

Very informative. My old Central heating system needs a refresh and the flow is lowish. Great to know about these and I will get the flow and pressure tested to help decide on the best solution for this house. Remove the tanks and Combi seems like a good option now. Cheers Roger

Excellent video and explanation. I couldn't help notice that the kitchen faucet handle is dripping...

I had the same issue - a 15mm main but just over 3 bar pressure. Swapped the cold tank in the loft for 2 x 250L Stuart Turner horizontal vessels. It made a huge difference. Two points to note though: 1. you need to check the pressure at the tank and adjust the air pressure in the bladder accordingly (from memory i think it was about one bar lower than the water pressure. 2. The stored water warms up over time so drinking water isn't as cold. I would recommend fitting a supply to a tap with a non return valve before the accumulators if possible, assuming you've got the pressure and reasonable flow for it.

Top marks - brilliant explanation throughout
