    Hi

    My sons shower pressure in his new house is not the best and is looking how to make it better

    He has a Worcester combi boiler which is still in warranty and Been serviced which is in the kitchen
    The shower is a mira electric shower and the stream is not good at all

    Water board been out checked water pressure to property said is within their tolerance and they are 300 yards from a water Tower which apparently doesn't help

    Tried new head new flexi pipe they are in the new year/spring going to get the bathroom gutted and fitted

    They not sure what to do to improve it would it be better just direct off the combi boiler or a higher kW shower or power shower or something else work??

    Thoughts and help appreciated

    Run it off the boiler instead. I've never used an electric shower that's remotely comparable

    Why have an electric shower with a combiboiler? Isnt the whole idea of them near instant hot water on demand?

    Every electric shower I've had the misfortune of having is low pressure, assumed the shower intentionally lowers the stream to be able to heat the water

    IMO an electric shower is OK to use in combination with a combi boiler because you still have hot water and can keep clean should the boiler fail, which it does occasionally.

    Also, the shower doesn't go cold suddenly should someone else turn on a hot tap :)

    But with our last one, does go scorching hot if someone turns the cold tap on or flushes the toilet

    OK. However we don't have that problem as the cold feeding the electric shower is mains water pressure.

    Problem maybe all down to mains water pressure?

    Have you checked out the quality level of your Mira shower ie how much it cost? Mira make both cheap and expensive showers. The Mira sport is amazing, their cheap models I would never buy.

    Also I'm assuming that the water shoots out when the water is set at cold but dribbles when heated? In which case you might have a low kw shower (around 8kw) that needs changing to something like a 10.5kw one to get what you need.

    Ps mains pressure minimum is set pretty low as you have discovered. It's either 1 bar or max 1.5 bar if memory serves right

    They just need a thermostatic mixer shower. Run it off boiler than job done.

    That is the other option :rotfl:

    As per normal it's just a matter on what the cheapest/best option is

    I think any option is going to be around the £150-£200 mark because of installation costs and materials.

    Unless the stop cock needs turning up of which it'll be free :D

    Electric showers heat the water up a few degrees quickly, the fact is though as the ambient water temperature drops in winter it has to raise it more degrees to get to the same temperature. If the power rating isn't good enough then it drops the flow rate to try and compensate and you end up with next to no water coming out.

    Do you know the model and power rating the shower is. If it's a 9 or 10.5 kw then it's not a problem with the capability of the shower. If it's a 7kw job then it will be struggling with the recent drop in temperature.

    How new is this house? If it has a water tank in the loft space then a mixer shower in conjuction with a combi boiler makes for a fantastic shower.

    That's a pretty decent shower. If you turn it to cold can you measure the amount of litres that come out in 1 minute compared to the bath and basin in the same area?

    Not unusual if you have a combi boiler and shouldn't stop you fixing a thermostatic mixer shower.

    Not got a flow limiter in it somewhere? I had this issue appear suddenly a while back. Turns out someone had given it the misses to save water and she actually fitted it herself. Thing was awful

    Needs to be clarified if it's a pressure or flow issue as they are two different things.

    Lol I'll get him to test the water flow as suggested earlier for 1 minute and see the results

    Read some random review of shower heads in an on-line review a couple of months ago and the best, apparently was one made by Triton - it was also the cheapest iirc. It's this one -

    Triton.JPG

    It's very neatly styled and it does give a better shower than what we had before, so well worth the £11.99 I paid on Amazon Prime (this is beginning to sound like a bleedin' advert :laugh:).

    So, worth a try, I'd say. Update - looks like it's £13.99 now :(.

    Never posted a URL on here before, hope this works https://www.amazon.co.uk/Triton-Pos...510346709&sr=1-4&keywords=triton+shower+heads

    I did chuck out the restrictor that we got in a free pack from our water supplier a year or two ago, btw, it just slowed the flow down too much, and we're not on a meter anyway ;).

    My old Mira Electric can almost knock tiles off on minimum temp. But to use it to shower with at a nice temp? It's rubbish. Nothing wrong with it, you can get it really hot, if you only want a dribble.

    Those tiles look identical to the type I’ve been installing this week.

    Wickes Nickel Finsh Straight Service Valve 15mm | Wickes.co.uk

    This sort of cheap valve acts to restrict flow slightly when fully on, and to compound the problem they can get gunked up. I had a problem with water pressure in my bathroom upstairs (the shower became rubbish) because of this.

    A wise old plumber pointed this out to me and showed me what the problem was. The quick fix was to turn the taps on in the bathroom and he found the valve feeding the water upstairs. He rotated 360deg the on/off screwdriver thing on the valve several times. A not inconsiderable amount of gunk came out of the taps. The result, the flow to the bathroom increased considerably and the shower now works just fine.

    :)

    Those valves are fitted to all my cold and cold feeds to taps and also feeds to toilets.

    Very useful to control the flow and to turn off to change washers/maintenance/replacements. The previous owner had them fitted and I never realised how useful they are.

    True. The plumber I had in showed me the valves he fits. The valve body looks just a bit 'fat' compared to the copper pipes. he pointed out that when these are fully open they don't restrict flow at all whereas the cheap ones will slightly restrict flow when fully open.

    :)

    BTW. The plumber found the gunked up valve by turning the bathroom taps on full and then by going around my pipes listening to the flow using a large wooden handled screwdriver, wooden end to his ear metal end on the pipe - pretty cool!
