We\\\'ve recently had 2 pumps fitted in the loft to boost the showers in the main and en-suite bathrooms.
Showers are great if only cold water is used, but when temperature is increased to include hot water the pumps start making a rhythmic pulsating noise and the water pressure drops. The showers also intermittently \\\'spurt\\\' as if there\\\'s air in the pipes.
A plumber came and changed the pipe work into the hot water tank to a wider bore. No difference.
Another plumber said we might need a larger tank in the loft, and another said an Essex flange was needed.
We\\\'ve spent a fortune already and don\\\'t want to spend more on ifs and maybes. Are any of the suggestions given to us correct?
