Increasing pressure of my shower upstairs

katy123

Our system is an open ended conventional boiler system with the hot water cylinder located upstairs in the airing cupboard. The cold water tank is in the attic. The water flow during showering is very weak. What is the most easier way to increase the water pressure for a better shower experience. THanks.

Pump it. Separate (from all other drawoffs) cold feed from CSWT in roof to pump. Separate hot feed from cylinder (via top or side mounted flange) to pump. Output from pump to shower. Pump can be in roof or adjacent to cylinder - just make sure its piped properly.

Oh and you won't increase the pressure what you will do is increase the flow rate which is actually what you want.

Still got that mouse in your boiler or has he left yet?

I'm not arguing, keystone, just interested, as a layman. If you pump more water through the same pipe, and it comes to the same restriction, ie the shower head, would that not increase the pressure at the head, and result in a brisker flow of water? I have a similar problem, and I thought about a pump, just didn't know what real difference it would make to the force of the shower.

Yes because its a flow rate issue. The pump just increases the volume of water through the pipe in a given timespan.

Keysonte, thanks for your prompt reply--always the first. We finally got the fan replaced today -£310 including service. THe aranged 2 apointments & the guy didn't take up so third time lucky today.

Your instructions sound quite complicated, need to look into it. We need to power flush our system £320 + mag filter £110 and got quoted £400 to install a pump. So the total bill if we proceed is £1,140. Kinda having second thoughts why we didn't just get a combi installed for £2,800 when we did our kitchen and we won't have these problems.

I need to google your abbreviations

(drawoffs)
CSWT
mounted flange)

Thanks once again:)

Well not realy I just happened to sign in with a cup of tea just after you posted.

Why do you need a powerflush and a mag filter? Does the £400 include supply of pump? What pump?

drawoffs - length of pipe terminating in a tap.
CSWT - cold water storage tank
mounted flange - flange mounted in the top or side of the cylinder.

Advised to get a power flush & install a mag filter because the bottom of a few radiators are cold and hot on top. This alone is £430 & £400 on top to install a shower pump.

I normally go to youtube for how to guides but none for installing a shower pump.:p

So "need" really means "might benefit from"? If its only a few there are other cheaper methods and perhaps, on a prioritisation andf budgeting basis, your CH doesn't need a powerflush right at the time of year that you are turning the heating off.

.............£400 on top to install a shower pump.

Does the £ 400 include the pump?

Go to the Techflow or Stuart Turner sites. There are a very good installation guides on both in pdf format. Both brands are very good pumps and IIRC, Stuart Turner now owns Techflow anyway.

£400 includes a £200 pump-he didn't specify a brand. I'm checking out the sites now and will get my dad to take a look to see if he can help. Many thanks for your advice....

Keystone, can you help with my other post?

thanks for all the replies...i've just bought a pump but struggling how to install it, i can do the electrics, just not sure where to source the hot feed from. There's mention of a surrey flange (but i don't think this is compulsory) the hot pipe comes out from the top of the cylinder and goes straight into the ground (so i don't see it split off to the different hot outlets) can i just cut the pipe (about 10 inches) to connect the pump at the section just before it goes into the floor thus pumping all hot water outlets? I''ve also read about that right angles causes bubbles in the pipe? what is this about?

If i do need to install a surrey flange, is this an easy undertaking? Many thanks.
